[gdb/contrib] Add words.sh script

Add a script that takes a list of files as arguments and output a list of
words from the C comments with their frequencies.

For:
...
$ ./gdb/contrib/words.sh $(find gdb -type f -name "*.c" -o -name "*.h")
...
it generates a list of ~15000 words prefixed with frequency.

This could be used to generate a dictionary that is kept as part of the
sources, against which new code can be checked, generating a warning or
error.  The hope is that misspellings would trigger this frequently, and rare
words rarely, otherwise the burden of updating the dictionary would be too
much.

And for:
...

2004, and only for ld.  gas and binutils support is lacking, and there
have been no commits to bfd/elf32-cr16c.c other than warning fixes or
global maintainers making changes to all targets.  I see no maintainer
listed for CR16C, and no commits from anyone at NSC supporting the
target.  Furthermore, at the time the CR16 support was added in 2007,
config.sub was changed upstream to no longer recognise cr16c as a
valid cpu.  That means the CR16C ld support is only available as a
secondary target by configuring with, for example,
--enable-targets=all or --enable-targets=cr16c-unknown-elf.  No
testing of the CR16C target is possible.

The target list was supposed to be more or less alphabetically sorted,

architecture variants together seems odd to me, and is no doubt the
reason why ix86 and x86_64 were grouped together, so I removed that
comment.  The patch doesn't change order of entries for a given cpu.

Alan Modra [Fri, 1 Nov 2019 03:15:25 +0000 (13:45 +1030)]
GENERATE_SHLIB_SCRIPT vs. EMBEDDED.

A target that sets EMBEDDED non-empty is one that doesn't want to put
the ELF file header or program header in a memory image.  Likely the
target isn't interested in supporting dynamically loaded executables,
shared libraries, or PIEs, because loaders for such binaries generally
require program headers to be present.  This isn't 100% true though.
The target might be one where the loader accesses the file system in
order to retrieve headers.

Also, note that not all "shared libraries" require gcc -shared or the
shared library support in the linker.  I believe one implementation of
shared libraries on uclinux is like this.

So, this patch removes GENERATE_SHLIB_SCRIPT and GENERATE_PIE_SCRIPT
in most emulparams files where EMBEDDED is set, restoring the shared
lib and pie support in emulparams files that unset EMBEDDED after
including a file where the support is removed.

Exceptions to the general rule that EMBEDDED disables shared libs are:
  arm*-*-symbianelf*, where the OS wants shared library support
  without ELF program headers in the image, and

  sh*-*-uclinux*, where I've left things as they were, ie. both

5 years ago[ARM, thumb] Fix disassembling bug after reloading a symbol file
Luis Machado [Fri, 1 Nov 2019 13:11:17 +0000 (10:11 -0300)]
[ARM, thumb] Fix disassembling bug after reloading a symbol file

The speed optimization from commit 5f6cac4085c95c5339b9549dc06d4f9184184fa6
made GDB skip reloading all symbols when the same symbol file is reloaded.

As a result, ARM targets only read the mapping symbols the first time we
load a symbol file. When reloaded, the speed optimization above will
cause an early return and gdbarch_record_special_symbol won't be called to
save mapping symbol data, which in turn affects disassembling of thumb
instructions.

First load and correct disassemble output:

Dump of assembler code for function main:
    0x0000821c <+0>:     bx      pc
    0x0000821e <+2>:     nop
    0x00008220 <+4>:     mov     r0, #0
    0x00008224 <+8>:     bx      lr

Second load and incorrect disassemble output:

Dump of assembler code for function main:
    0x0000821c <+0>:     bx      pc
    0x0000821e <+2>:     nop
    0x00008220 <+4>:     movs    r0, r0
    0x00008222 <+6>:     b.n     0x8966
    0x00008224 <+8>:     vrhadd.u16      d14, d14, d31

This happens because the mapping symbol data is stored in an objfile_key-based
container, and that data isn't preserved across the two symbol loading
operations.

The following patch fixes this by storing the mapping symbol data in a
bfd_key-based container, which doesn't change as long as the bfd is the same.

I've also added a new test to verify the correct disassemble output.

5 years agogdb: Add new commands to list module variables and functions
Andrew Burgess [Wed, 10 Jul 2019 14:54:03 +0000 (15:54 +0100)]
gdb: Add new commands to list module variables and functions

This patch adds two new commands "info module functions" and "info
module variables".  These commands list all of the functions and
variables grouped by module and then by file.

For example:

  (gdb) info module functions
  All functions in all modules:

  Module "mod1":

  File /some/path/gdb/testsuite/gdb.fortran/info-types.f90:
  35: void mod1::__copy_mod1_M1t1(Type m1t1, Type m1t1);
  25: void mod1::sub_m1_a(integer(kind=4));
  31: integer(kind=4) mod1::sub_m1_b(void);

  Module "mod2":

  File /some/path/gdb/testsuite/gdb.fortran/info-types.f90:
  41: void mod2::sub_m2_a(integer(kind=4), logical(kind=4));
  49: logical(kind=4) mod2::sub_m2_b(real(kind=4));

The new commands take set of flags that allow the output to be
filtered, the user can filter by variable/function name, type, or
containing module.

As GDB doesn't currently track the relationship between a module and
the variables or functions within it in the symbol table, so I filter
based on the module prefix in order to find the functions or variables
in each module.  What this makes clear is that a user could get this
same information using "info variables" and simply provide the prefix
themselves, for example:

  (gdb) info module functions -m mod1 _a
  All functions matching regular expression "_a",
   in all modules matching regular expression "mod1":

  Module "mod1":

  File /some/path/gdb/testsuite/gdb.fortran/info-types.f90:
  25: void mod1::sub_m1_a(integer(kind=4));

Is similar to:

  (gdb) info functions mod1::.*_a.*
  All functions matching regular expression "mod1::.*_a":

  File /some/path/gdb/testsuite/gdb.fortran/info-types.f90:
  25: void mod1::sub_m1_a(integer(kind=4));

The benefits I see for a separate command are that the user doesn't
have to think (or know) about the module prefix format, nor worry
about building a proper regexp.  The user can also easily scan across
modules without having to build complex regexps.

The new function search_module_symbols is extern in this patch despite
only being used within symtab.c, this is because a later patch in this
series will also be using this function from outside symtab.c.

This patch is a new implementation of an idea originally worked on by
Mark O'Connor, Chris January, David Lecomber, and Xavier Oro from ARM.

Implement convenience functions to examine GDB settings.

The new convenience functions $_gdb_setting and $_gdb_setting_str
provide access to the GDB settings in user-defined commands.
Similarly, $_gdb_maint_setting and $_gdb_maint_setting_str
provide access to the GDB maintenance settings.

The patch was developed following a comment of Eli about the
'set may-call-functions'.  Eli said that user-defined functions
should have a way to change their behavior according to this setting.
Rather than have a specialized $_may_call_functions, this patch
implements a general way to access any GDB setting.

Compared to doing such access via Python 'gdb.parameter' and/or
'gdb.execute("set somesetting tosomevalue"):
* The 'with' command is much better than the above python usage:
  if the user types C-c or an error happens between the set pagination off
  and the python "set pagination on", the above python
  does not restore the original setting.

* Effectively, with the "gdb.parameter" python one liner, it is possible to do
  simple 'if' conditions, such as set and restore pagination.
  But mixing the "python if" within canned
  sequence of commands is cumbersome for non trivial combinations.
  E.g. if several commands have to be done for a certain condition
  accessed from python, I guess something like will be needed:
     python if __some_setting: gdb.execute("some command")
     python if __some_setting: gdb.execute("some other command")
     python if __some_setting: gdb.execute("some different command")
  (without speaking about nested "if-s").

  With the convenience function:
     if $_gdb_setting("some_setting")
        some command
        some other command
        some different command
     end
  Integer settings (for example print elements) will also be more difficult
  to use.
  For example, a user defined function that scans and prints a linked list
  might want to use the value of "set print elements" to stop printing
  the linked list.
  Doing that by mixing python expression/if is likely doable, but seems
  not easy with the above one liners.

So, in summary, the $_gdb_setting and $_gdb_setting_str avoids to have the
heterogeneous mix of python and GDB commands in one single script
(and of course, it works even if python is not configured, but that
must be an unusual setup I guess).

the present defaulting of operand sizes won't get broken. There are a
few anomalies pointed out by this:
- arithmetic insns (add, sub, etc) allow defaulting when their immediate
  fits in (signed) 8 bits, but they fail to assemble with larger values,
- mov, other than arithmetic insns, doesn't allow any defaulting,
- movsx/movzx default to byte sources (in AT&T mode), and their special
  casing needs to be adjusted first
- bt and friends allow defaulting, while shl and friends don't,
- ambiguous AVX and AVX512 insns don't allow defaulting.
This should ultimately all become consistent (perhaps with the exception
some of the SIMD insns); respective tests will be added to the test
cases here as the issues get addressed.

Only make a nullterminated string if we need to

As of 7bb43059820c5febb4509b15202a93efde442bc6, we no longer need
a nullterminated linkage_name to look up the entry in the hash table.

So this patch makes it so we only make the copy if the entry was
not found.

By auditing all callers of symbol_set_names, I found out that all cases
where the string may not be nullterminated already pass true for COPY_NAME.
So here, I am documenting that as a requirement and am removing the code
that relies on undefined behavior in symbol_set_names (it accessed the string
past the provided length to check for nulltermination). Note that the Ada
case at the beginning of symbol_set_names was already relying on this.
