+
+Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Add Andrew Beers' changes for Modula-2 support. His ChangeLog
+ entries are enclosed herein:
+
+Mon Jun 3 17:05:45 EDT 1991
+
+ m2-exp.y Created. Tested outside of GDB for a few days. Proper
+ operators were added, C specific operators and tokens
+ removed. yylex() revamped to some extent. Still things
+ missing from the grammar, such as sets.
+ Tested for two weeks in GDB v3.5.
+
+Tue Jun 11 17:23:48 EDT 1991
+
+ m2-exp.y Added boolean constants TRUE and FALSE to the grammar
+ so they are built-in. Sort of a hack.
+
+Fri Jun 14 12:53:51 EDT 1991
+
+ m2-exp.y Added range checking for numeric constants. Any numeric
+ constant is assumed to be of builtin type INTEGER unless:
+ (1) it is octal or hexadecimal, in which case it is a
+ CARDINAL; (2) it is too big to fit into an INTEGER, in
+ which case it is a CARDINAL.
+ eval.c Added simple range checking for +, -, and * on integers.
+ Doesn't work very well for *, since 6 * 1,000,000,000 =
+ 1,705,032,704, which fails the simple test of result >=
+ first_operand, no matter in what order the operands are.
+
+Tue Jun 18 14:11:30 EDT 1991
+
+ Broke the parser into parts, one containing the C grammar and the other
+ containing code to be shared by all of the grammars.
+
+ The following files no longer exist:
+
+ expread.y
+ expread.tab.c
+
+ The following files were added:
+
+ c-exp.y (The C grammar)
+ m2-exp.y (The Modula-2 grammar)
+ parser-code.c (Code that is shared by the above grammar)
+ parser-code.h
+ parser-defs.h
+
+ Makefile.dist Changed to reflect the above dependencies. NOTE: It is
+ now necessary to use the Bison compiler compiler, since it
+ will generate function/variable prefixes other than yy.
+
+Tue Jun 18 16:47:49 EDT 1991
+
+ symtab.[ch] Added the external variable working_lang, than holds the
+ value of the current working language.
+ Added the ennumerated type language_mode, with the values
+ language_auto and language_manual, the former meaning that
+ GDB sets working_lang as needed, and the latter meaning
+ that the value of working_lang is totally under user
+ control.
+ symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
+ REAL, BOOLEAN and CHAR. Also added the type codes
+ TYPE_CODE_BOOL and TYPE_CODE_CHAR.
+ utils.c Added set_language_command and show_language_command to
+ implement the GDB support commands "set language" and
+ "show language".
+ expression.h A number of identifiers were added to the type exp_opcode
+ to facilitate Modula-2 builtin functions, integer
+ division, and array indexing.
+
+Wed Jun 19 13:25:58 EDT 1991
+
+ language.h Added the macro STRICT_TYPE, which evaluates to non-zero
+ if the language specified by working_lang requires the use
+ of strict typing of expressions. Eventually, even this
+ will be able to be changed by the user.
+ Added the macro RANGE_CHECK, which evaluates to non-zero
+ if the language specified by working_lang requires the
+ checking of a value against the domain of its type.
+ Eventually, even this will be able to be changed by the
+ user.
+ language.[ch] Predicates involving types (simple_type, ordered_type,
+ same_type, integral_type, numeric_type, character_type,
+ boolean_type, float_type) are added. These predicates are
+ based on the current value of working_lang, and are handy
+ in type-checking.
+
+Wed Jun 19 15:39:34 EDT 1991
+
+ eval.c Added the function type_array_rank which computes the rank
+ of an array type.
+ valarith.c Added the funtion value_bool, which when given a integer
+ value.h value (ie. struct value *) as an argument, it returns a
+ boolean value (ie. struct value *) true if that integer
+ is non-zero, and a boolean value false otherwise.
+ valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
+ will print out properly.
+
+Wed Jun 19 16:36:34 EDT 1991
+
+ valops.c Added the function value_capitalize, which returns it
+ value.h argument capitalized if its argument is a lowercase
+ letter, or the argument unchanged if its argument is not a
+ letter.
+ valarith.c Added the function range_check_p, which returns non-zero
+ value.h if its value argument is between the integral bounds upper
+ and lower.
+ Added the function range_check_enum_p, which makes sure
+ that its value argument is a valid member of the domain of
+ its type argument.
+ Added the function range_check_range_p, which makes sure
+ its value argument lies between the upper and lower bounds
+ of its type argument, which must be a ranged type.
+ Added the function check_array_index, which range and type
+ checks an index of an array.
+ Added the function value_multi_subscript, which computes
+ array[idx1,idx2...idxN], given a value array and an array
+ of values representing indicies.
+ values.c Changed value_from_long to work with TYPE_CODE_CHAR and
+ unpack_long to work with TYPE_CODE_BOOL and
+ TYPE_CODE_CHAR.
+
+Wed Jun 19 18:04:08 EDT 1991
+
+ symtab.c Stored pervasive types in a structure and make
+ lookup_pervasive_type() a lookup function that was based
+ on working_lang. If lookup_pervasive_type() returned
+ non-zero, then that value was returned (a fix, since
+ before it simply wouldn't return the pervasive type.)
+ language.h Added the macro CAST_IS_CONVERSION, which evaluates to
+ non-zero if the language specified by working_lang means
+ "conversion" when it says "cast".
+ valops.c Added the function value_real_cast(), which performs a
+ value.h *cast*, not a *conversion*, which is what value_cast()
+ does when it can. In particular,
+ value_cast(<float_type>,4) = 4.0, while
+ value_real_cast(<float_type>,4) = some mess.
+ eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
+ parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
+ expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
+ and MIN on integral types. *NOTE*: These are currently
+ hardcoded to work only if there are 8 bits per storage
+ unit. FIXME.
+ eval.c Made logical functions call value_bool to return a
+ properly typed boolean value, based on working_lang.
+
+Thu Jun 20 11:55:27 EDT 1991
+
+ valprint.c Types now print out in a Modula-2 fashion. This works for
+ the cases when the type is printed out step-by-step, that
+ is, it doesn't work when the name of a structured type
+ (which includes the keyword "struct", etc.) is simply
+ displayed.
+ FIXME: Perhaps this is bad. Parts of it seem to kludgey,
+ since type specifications in C and Modula-2 are very
+ different. The C printing of a type is very recursive,
+ whereas in Modula-2 it is generally very simple. C has
+ type prefixes and suffixes, which have no real analogue in
+ Modula-2. Maybe type_print() should call a language
+ specific type printer. This is also advantageous if we
+ compile GDB to exclude some of the languages. We'll just
+ leave those functions out.
+
+Thu Jun 20 16:57:10 EDT 1991
+
+ dbxread.c When reading the complete symbol table in (via
+ psymtab_to_symtab()), the number and types of function
+ arguments are added to a function type. define_symbol()
+ calls add_param_to_type() to accomplish this.
+ Assumption: when we come across a function definition
+ (N_FUN symbol with an 'f' or 'F' in the name), its
+ arguments will appear before another function definition.
+ When a function is found, a pointer to its type is placed
+ in the global in_function_type. Changes that
+ add_param_to_type() makes are to this global.
+ valprint.c The type of a function now includes (for Modula-2) the
+ types of its parameters.
+ eval.c Type checking and a check for the proper number of
+ arguments is now done for function calls. Not sure of the
+ impact this has on C++ member function yet.
+
+Thu Jun 20 19:58:48 EDT 1991
+
+ valprint.c Rewrote the type printer. Broke it into two language
+ specific parts, adding the functions type_print_m2() and
+ type_print_m2_1().
+ An unfortunate consequence is this: if you debugging a C
+ program in Modula-2 mode (why?), info types does not work
+ well with regular expressions, since the types are printed
+ out in Modula-2 terminology, but stored in C terminology.
+ language.[ch] Added the functions new_type_last(), type_keyword(), and
+ type_sep() to aid in the printing of typedefs.
+ symtab.c Made the printing of typedefs as language independent as
+ possible through calls to new_type_last(), type_keyword(),
+ and type_sep().
+
+Fri Jun 21 11:50:26 EDT 1991
+
+ dbxread.c Check all incoming ennumerated types. If it looks like
+ Modula-2's BOOLEAN type, then change the type_code of the
+ type to TYPE_CODE_BOOL so we can process it as a boolean
+ variable.
+ valprint.c Replaced some of the 0x%x with calls to sprintf and
+ hexformat() in val_print().
+ language.[ch] Added the function hex_to_string(), which converts its
+ integral argument to a hexadecimal number (format is
+ language based) and returns the result as a string.
+
+Mon Jun 24 12:25:07 EDT 1991
+
+ valprint.c Some functions call type_print_1() directly, instead of
+ value.h using type_print(), so they can specify where (column) to
+ print things. Since type_print() takes care of language
+ dependence, that needs to be called first. Added a
+ parameter depth to type_print() (so it is now like
+ type_print_1). Changed type_print to type_print_at, and
+ made type_print a macro that passes a depth argument of
+ zero.
+ symmisc.c Changed all calls to type_print_1 to calls to
+ type_print_at.
+ Makefile.dist Made it possible to build GDB for a specific set of
+ depend languages. Do this by passing a definition for the macro
+ LANGS to make. LANGS should be a string containing a
+ space-separated list of language names (ie. LANGS="c m2").
+ The default is to build all languages. Note that grammar
+ files must follow the naming convention of <lang>-exp.y.
+ gdb.lang This holds the current value of the LANGS macro. It is
+ examined every time make is called, and is updated if
+ necessary.
+ eval.c Added #ifdef _LANG_<lang> to these files.
+ expread.c Still need to add them to dbxread.c and coffread.c.
+ main.c
+ source.c
+ symtab.c
+ utils.c
+ valarith.c
+ valprint.c
+
+Mon Jun 24 16:33:11 EDT 1991
+
+ language.[ch] Added the functions hexformat_pre() and
+ hex_to_string_pre(), which take a prefix argument to
+ include in the format string. Thus, hexformat_pre("08") will
+ return "0x08x" (if the working language is language_c).
+ Made hexformat() and hex_to_string() calls to the above
+ with "" as the prefix argument.
+
+ am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
+ dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
+ infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
+ mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
+ pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
+ stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
+ valprint.c, vax-pinsn.c
+
+ Changed all occurences of 0x%[0-9]*l*x in printf format strings to
+ calls to hexformat() and hex_to_string(). Format strings without
+ the leading "0x" were ignored.
+
+ depend Updated to take the above into account.
+
+
+Tue Jun 25 15:27:18 EDT 1991
+
+ symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
+ and type_check_t to keep track of the current state of
+ range and type checking.
+ main.c Added the variables range_mode, range_check, type_mode,
+ and type_check to record the current state of range and
+ type checking. Added initialization code to main().
+ language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
+ the above variables.
+
+
+Tue Jun 25 17:57:08 EDT 1991
+
+ dbxread.c process_one_symbol() updates the variable (enum language)
+ source_lang based on the extension of the filename
+ contained in the N_SO sybmol that started this symtab.
+ When end_symtab() is called, the value of source_lang is
+ put into the language field.
+ stack.c select_frame() sets working_lang (and possibly type_check
+ and range_check) to the language field of the symtab
+ associated with the frame that is selected if working_mode
+ is language_auto. If working_mode is language_manual, a
+ warning is printed and working_lang is not set.
+ language.c Added the function set_type_range(), which sets the value of
+ type_check and range_check (if their modes call for
+ automatic setting) based on the current value of
+ working_lang. A non-zero argument will cause the current
+ settings to be output.
+
+
+Wed Jun 26 14:51:40 EDT 1991
+
+ eval.c Added range checks on assignment.
+ m2-exp.y Added the grammar for sets to the language. Currently,
+ these do not do anything except print an error message.
+
+Wed Jun 26 17:01:04 EDT 1991
+
+ m2-exp.y Added the ability for parse_number() to parse negative
+ numbers. A global flag is set upon encountering a unary
+ minus. This was done to make, for example, 1 parse as a
+ CARDINAL, and not as an integer, per Wirth's examples in
+ Programming in Modula-2 ed.4.
+ valprint.c Added support for "set radix 2" by then setting
+ output_format to 't'.
+ eval.c Implemented range checking on subrange types. Added calls
+ to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
+ Implemented MIN and MAX for ennumerated types. The
+ minimum value of an ennumerated type is defined by Wirth
+ as the first identifier, and the maximum as the last.
+ m2-exp.y Made octal numbers ending with "B" be characters and those
+ ending with "C" be numbers, per Wirth's book. (p. 34)
+
+Thu Jun 27 14:11:52 EDT 1991
+
+ stack.c select_frame() now only sets working_lang, it does not
+ notify the user. If working_mode is language_manual, then
+ a warning is issued once.
+ main.c At the end of each call to execute_command(), working_lang
+ is checked against the local static (enum language)
+ current. If they differ and working_mode is
+ language_auto, the new settings of language, type and
+ range checking are printed out.
+ stack.c Modified frame_info() to include the language of the
+ current frame in the output of "info frame".
+ language.[ch] Added the function language_str() which returns the name
+ of the current language.
+
+Fri Jun 28 15:33:14 EDT 1991
+
+ m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
+ the language. INCL and DECL currently cause an error,
+ since sets are not implemented yet. INC and DEC are
+ implemented as PREINCREMENT/PREDECREMENT with one
+ argument, and as ASSIGN_MODIFY with two arguments.
+ eval.c Added type checking to the above cases.
+ value.h Added not_lval_constant to the lval_type ennumerated type.
+ not_lval_constant means that the value is a constant
+ value; that is 3 or 'a' or TRUE, not as in a constant
+ identifier. This is used to help coerce numbers such as 3
+ to either signed or unsigned numbers.
+ valops.c Added the function value_coerce_constants() which coerces
+ constant integers as following: if one is a constant and
+ the other is not, the constant's type is set to the type
+ of the other argument. If both are constants and one is
+ signed, the other is converted to a signed constant.
+
+Sat Jun 29 17:26:29 EDT 1991
+
+ valarith.c Added a better range checker. It now checks range
+ (successfully) on integral operations [+-] (signed and
+ unsigned) for any C sized type. Still does not work well
+ for multiplication.)
+ int_in_size() returns an integer that is coerced to fit into
+ specified number of bytes.
+
+Mon Jul 1 13:04:14 EDT 1991
+
+ language.[ch] Added the function binop_result_type(), which returns the
+ builtin (struct type *) type that would be the result of a
+ binop on the two values V1 and V2.
+
+Wed Jul 3 19:22:53 EDT 1991
+
+ source.c Extended source_info() to include the source language in
+ the output from "info source".
+
+Fri Jul 5 13:48:52 EDT 1991
+
+ utils.c Moved the support functions for the GDB set/show commands
+ dealing with language into language.c.
+ language.c Added the function language_info(), which displays info
+ about the current working language, type and range check
+ settings. Called via the GDB command "info language".
+ Added an initialization routine _initialize_language(),
+ that sets defaults for the language, type and range
+ variables and sets up the new GDB commands.
+ main.c Language setup moved to language.c.
+ depend Rebuilt.
+
+Mon Jul 8 10:10:22 EDT 1991
+
+ valarith.c Debugged the range checker for arithmetic. Still does not
+ work for multiplication very well.
+
+Mon Jul 8 12:40:37 EDT 1991
+
+ language.[ch] Added the function value_true() which returns non-zero if
+ its argument represents a boolean true value.
+ breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
+ check the truth of an expression.
+
+Thu Jul 11 12:51:34 EDT 1991
+
+ language.[ch] Added the predicate structured_type(), which returns
+ non-zero if the argument is a structured type.
+ Added the predicate pointer_type(), which returns non-zero
+ if the argument is a pointer type.
+ eval.c Added the ability to do addition and substraction on
+ pointers and integers. This case simply bypasses the
+ type checker.
+
+Thu Jul 11 14:41:42 EDT 1991
+
+ include/stab.def
+ Added the symbol N_DEFD (0x4a) which is a definition
+ module dependency that is used by the GNU Modula-2
+ compiler and the linker. It is not important to GDB,
+ except that [dbx|coff|mips]read.c should ignore these
+ symbols.
+
+Fri Jul 12 16:07:00 EDT 1991
+
+ valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
+ 0 in val_print(). Also added statements to the else part
+ to coerce type (argument to val_print) to a pointer type
+ if it is an "array of unspecified length".
+ valops.c Added the function value_m2_string(), which returns a
+ (value) value which is a constant string, whose type is
+ (ARRAY [0..n] OF CHAR). The length field of the type
+ structure is set to zero, so it will be interpreted as an
+ "array of unspecified length".
+ stack.c Moved the language/frame mismatch check to
+ main.c:execute_command().
+ main.c The working language is recorded each time
+ execute_command() is executed. If working lang has
+ changed during its execution, then the new
+ language/type/range info is printed out for the user. If
+ the working language does not match the language of the
+ frame, a warning is issued.
+
+Sat Jul 13 16:16:39 EDT 1991
+
+ eval.c Moved all the type-checking stuff for operators to
+ language.[ch] language.c. This is so we can keep language-specific
+ stuff (like for what type operators are defined) in
+ language.c.
+ language.[ch] Added the function binop_type_check(), which checks to see
+ if its two (value) arguments are type-compatible with its
+ opcode argument. The opcode should represent an operation
+ involving an operator. Also added the macro function
+ unop_type_check, which calls binop_type_check with a
+ NULL second argument.
+ expprint.c Added Modula-2 operators to the op_print_tab, so info
+ expression.h break works correctly. Also added "op_string", which
+ returns the string corresponding to the (enum exp_opcode)
+ opcode that is its argument.
+
+
+Sat Jul 13 18:26:18 EDT 1991
+
+ coffread.c Added code to record the type of function arguments with
+ each paricular function. Code is very similar to that
+ added to dbxread.c.
+ dbxread.c Moved add_param_to_type() to symtab.c
+ symtab.[ch] Added function add_param_to_type() from dbxread.c
+
+ *** NOTE: The above additions have not been tested.
+
+Mon Jul 15 12:50:47 EDT 1991
+
+ langauge.[ch] Added the functions type_error and range_error, which work
+ like error() except if the type/range mode is set to
+ *_mode_warn, then they do not do a return_to_top_level(),
+ but merely print a warning.
+ Also changed [set|show]_[type|range]_command() to support
+ the new "warn" feature.
+
+Thu Jul 18 17:50:54 EDT 1991
+
+ mipsread.c Added code to record the type of function arguments with
+ each particular function. Code is very similar to that
+ added to dbxread.c.
+
+ *** NOTE: The above additions have not been tested.
+
+Fri Jul 19 11:19:10 EDT 1991
+
+ defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
+ UMIN_OF_SIZE, which when given a size of a numeric type,
+ return the maximum and minimum value it can hold. UMAX...
+ and UMIN... return the result for unsigned types.
+ symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
+ struct types. They call above macros.
+ dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
+ avoid a name conlict with the above.
+ c-exp.y Added range checking on numeric constants in
+ parse_number() for completeness.
+ valarith.c Made binop_user_defined_p() and unop_user_defined_p()
+ return 0 if working_lang is not language_c.

+
+ main.c
+ printcmd.c
+ breakpoint.c Documentation strings of some commands changed to
+ eliminate the references to the C language where
+ appropriate.
+
+Tue Aug 13 15:48:03 EDT 1991
+
+ m2-exp.y Added qualified identifiers to the grammar. The semantics
+ are slightly different from those of the GDB operator ::
+ c-exp.y
+ m2-exp.y Added a rule to each grammar of the form: start ::= exp |
+ type_exp, where type_exp is any valid type expression.
+ expression.h
+ eval.c Added the opcode OP_TYPE, and an error case in eval.c.
+ printcmd.c Modified ptype_command() so it actually parses the input
+ (necessary for type expressions with scope qualifiers).
+ Added the function ptype_eval() which expects an
+ expression composed of one OP_TYPE element.
+ *.[ch] Replaced all occurences of parse_c_expression with
+ parse_expression
+ *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1

+ John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
+
+ * utils.c (wrap_here): Avoid wrap action of fputs_filtered if

+ * coredep.c: include ptrace.h where necessary.
+ * mipsread.c(parse_lines): fix unsigned char problem that was
+ messing up line numbers on SGI's and possibly other MIPS based
+ platforms.
+ * infrun.c (child_create_inferior): use better test to check
