MIPS: Fix XPA base and Virtualization ASE instruction handling

Correct a commit 7d64c587c15f ("Add support for the MIPS eXtended
Physical Address (XPA) ASE.") bug, causing XPA base and Virtualization
ASE instructions to be wrongly always enabled with the selection of the
MIPS32r2 or higher ISA.

For example this source assembles successfully as shown below:

$ cat xpa.s
mfhc0 $2, $1
$ as -32 -mips32 -o xpa.o xpa.s
xpa.s: Assembler messages:
xpa.s:1: Error: opcode not supported on this processor: mips32 (mips32) `mfhc0 $2,$1'
$ as -32 -mips32r2 -o xpa.o xpa.s
$ objdump -d xpa.o

xpa.o:     file format elf32-tradbigmips

Disassembly of section .text:

00000000 <.text>:
   0: 40420800  mfhc0 v0,c0_random
...
$

To address this issue remove the I33 (INSN_ISA32R2) marking from all XPA
instructions in the opcode table.  Additionally, for XPA Virtualization
ASE instructions implement an XPAVZ (ASE_XPA_VIRT) combination ASE flag
and use it in place of IVIRT|XPA (ASE_VIRT|ASE_XPA).

Now the same source is correctly rejected unless the `-mxpa' option is
also used:

$ as -32 -mips32r2 -o xpa.o xpa.s
xpa.s: Assembler messages:
xpa.s:1: Error: opcode not supported on this processor: mips32r2 (mips32r2) `mfhc0 $2,$1'
$ as -32 -mips32r2 -mxpa -o xpa.o xpa.s

7 years agoExpression completer should not match explicit location options
Pedro Alves [Thu, 29 Jun 2017 14:52:38 +0000 (15:52 +0100)]
Expression completer should not match explicit location options

This commit fixes a mismatch between what "print" command completer
thinks the command understands, and what the command actually
understands.

The explicit location options are understood by commands that take
(linespecs and) explicit locations as argument.  I.e, breakpoint
commands, and "list".  For example:

 (gdb) b -source file.c -function my_func

So for those commands, it makes sense that the completer
completes:

 "b -sour[TAB]" -> "b -source "
 "b -functi[TAB]" -> "b -function "

etc.

However, completion for commands that take expressions (not
linespecs/locations) as arguments, such as the "print" command, also
completes the explicit location options, even though those switches
aren't really understood by these commands.  Instead, "-foo" is
understood as an expression applying unary minus on a symbol named
"foo" (think "print -1"):

 (gdb) p -func[TAB]
 (gdb) p -function [RET]
 No symbol "function" in current context.

The patch fixes this by having the expression_completer function
bypass the function that completes explicit locations.

New regression tests included.

[ARC] Fix handling of cpu=... disassembler option value

There is a bug in handling of cpu=... disassembler option in case there are
other options after it, for example, `cpu=EM,dsp'.  In this case `EM,dsp' is
treated as an option value, and strcasecmp reports is as non-equal to "EM".
This is fixed by using disassembler_options_cmp function, which compares string
treating `,' the same way as `\0'.

This function also solves a problem with option order in parse_option.
Previously, if several option had same prefix (e.g. fpud, fpuda), then the
longer one should have been compared first, otherwise when longer option is
passed it would be treated as a short one, because

  CONST_STRNEQ ("fpud", "fpuda")

would be true.  The order of options was correct for ARC, so there were no
bugs per se, but with disassembler_option_cmp there is no risk of such a bug
being introduced in the future.

Doug Gilmore [Wed, 28 Jun 2017 01:54:22 +0000 (02:54 +0100)]
Fix PR 21337: segfault when re-reading symbols.

Fix issue exposed by commit 3e29f34.

The basic issue is that section data referenced through an objfile
pointer can also be referenced via the program-space data pointer,
although via a separate mapping mechanism, which is set up by
update_section_map.  Thus once section data attached to an objfile
pointer is released, the section map associated with the program-space
data pointer must be marked dirty to ensure that update_section_map is
called to prevent stale data being referenced.  For the matter at hand
this marking is being done via a call to objfiles_changed.

Before commit 3e29f34 objfiles_changed could be called after all of
the objfile pointers were processed in reread_symbols since section
data references via the program-space data pointer would not occur in
the calls of read_symbols performed by reread_symbols.

With commit 3e29f34 MIPS target specific calls to find_pc_section were
added to the code for DWARF information processing, which is called
via read_symbols.  Thus in reread_symbols the call to objfiles_changed
needs to be called before calling read_symbols, otherwise stale
section data can be referenced.

Thanks to Luis Machado for providing text for the main comment
associated with the change.

Eliminate make_cleanup_obstack_free, introduce auto_obstack

This commit eliminates make_cleanup_obstack_free, replacing it with a
new auto_obstack type that inherits obstack to add cdtors.

These changes in the parsers may not be obvious:

 -  obstack_init (&name_obstack);
 -  make_cleanup_obstack_free (&name_obstack);
 +  name_obstack.clear ();

Here, the 'name_obstack' variable is a global.  The change means that
the obstack's contents from a previous parse will stay around until
the next parsing starts.  I.e., memory won't be reclaimed until then.
I don't think that's a problem, these objects don't really grow much
at all.

The other option I tried was to add a separate type that is like
auto_obstack but manages an external obstack, just for those cases.  I
like the current approach better as that other approach adds more
boilerplate and yet another type to learn.

Fix PR 13402

Fix incorrect adjustment of diff relocs when relaxing, and thus the
resulting source line to address mismatch.

Fix two issues when adjusting diff relocs to account for
deleted bytes.

1. Don't adjust the difference if the end address is the shrinked
insn's address i.e. use < instead of <=. The relaxation code deletes
count bytes from or after shrinked_insn_address, so the difference
between start_address and end_address should remain unchanged in this
case.

2. Adjust the reloc addend if the difference is to be adjusted and
symval + reloc addend is past the shrinked insn address. This is
because for a typical sym1 - sym2 diff reloc, sym1 is .text +
irel->r_addend, and the addend should be reduced to account for the
shrinked insn.

For example, assume the reloc value is .text + 0x8 with .text = 0, the
diff value in the object file = 0x4, and shrinked_insn_address = 0x4
with count = 0x2. Then the existing code writes 0x2 into the object
file to account for the deleted bytes, as shrinked_insn_address lies
between 0x8 and 0x8 - 0x4 = 0x4, but leaves the addend as is. The next
time the reloc is looked at, the code sees if a shrinked_insn_address
lies between 0x8 and 0x8 - 0x2 = 0x6, instead of 0x6 and 0x4. If there
happens to be one, then the diff value in the object file ends up
getting reduced again.

darwin: Do not add a dummy thread

Starting a process on macOS/Darwin currently leads to this error:

/Users/simark/src/binutils-gdb/gdb/darwin-nat.c:383: internal-error: void darwin_check_new_threads(struct inferior *): Assertion `tp' failed.

with the corresponding partial backtrace (sorry, taken with lldb,
because well, gdb is broken :)):

The issue was introduced by commit

  "Share fork_inferior et al with gdbserver"

because it changed the place where the dummy thread (pid, 0, 0) is added,
relative to the call to the init_trace_fun callback.  In this callback, darwin
checks for new threads in the program (there should be exactly one) in order to
update this dummy thread with the right tid.  Previously, things happened in
this order:

 - fork_inferior calls fork()
 - fork_inferior adds dummy thread
 - fork_inferior calls init_trace_fun callback, which updates the dummy
   thread info

Following the commit mentioned above, the new thread is added in the
darwin-nat code, after having called fork_inferior (in
darwin_create_inferior).  So gdb tries to do things in this order:

 - fork_inferior calls fork()
 - fork_inferior calls init_trace_fun callback, which tries to update
   the dummy thread info
 - darwin_create_inferior adds the dummy thread

The error happens while trying to update the dummy thread that has not
been added yet.

I don't think this dummy thread is necessary for darwin.  Previously, it
was fork_inferior that was adding this thread, for all targets, so
darwin had to deal with it.  Now that it's done by targets themselves,
we can just skip that on darwin.  darwin_check_new_threads called
indirectly by init_trace_fun/darwin_ptrace_him will simply notice the
new thread and add it with the right information.

My level of testing was: try to start a process and try to attach to a
process, and it seems to work somewhat like it did before.  I tried to
run the testsuite, but it leaves a huge amount of zombie processes that
launchd doesn't seem to reap, leading to exhaustion of system resources
(number of processes).

* darwin-nat.c (darwin_check_new_threads): Don't handle dummy
thread.

Available documentation[1][2] clearly indicates the LSI CW4010 processor
is only backwards compatible with the MIPS R4000 processor as far as the
latter's 32-bit instructions are concerned and consequently can only be
considered a MIPS II ISA implementation (with vendor extensions).

This fixes an LD testsuite failure:

FAIL: MIPS incompatible objects:  "-march=r4010 -32"      "-march=r4650 -32"

triggered for the `mips-sgi-irix5' and `mips-sgi-irix6' targets.

Remove this function, which, AFAIK, has never been used.  Note that GCC

    Warn whenever a static function is declared but not defined or a non-inline static function is unused.  This warning is enabled by -Wall.

vec: Silence -Wunused-function warnings on clang

clang has a too aggressive (or broken, depends on how you want to see
it) -Wunused-function warning, which is triggered by the functions
defined by DEF_VEC_* but not used in the current source file.  Normally,
it won't warn about unused static inline functions defined in header
files, because it's expected that a source file won't use all functions
defined in a header file it includes.  However, if the DEF_VEC_* macro
is used in a source file, it considers those functions as defined in the
source file, which leads it to think that we should remove those
functions.  It is therefore missing a check to see whether those
functions are resulting from macro expansion.  A bug already exists for
that:

  https://bugs.llvm.org//show_bug.cgi?id=22712

It's quite easy to silence this warning in a localized way, that is in
the DEF_VEC_* macros.

1) The main change is the addition of the logic for merging a file whose
Tag_CPU_arch build attribute is 15 (ARMv8-R). Namely, all pre-ARMv8 are
merged into ARMv8-R as well as ARMv8-R itself. ARMv8-A (14) merges into
ARMv8-A. ARMv8-M Baseline (16) and Mainline (17) are not allowed to
merge merge with ARMv8-R. Note that merging only occurs if the two
profiles are identical or one is S (Application or Realtime) and the
other is R.

2) using_thumb_only, using_thumb2_bl, using_thumb2 and arch_has_arm_nop
are updated according to capabilities of ARMv8-R and their BFD_ASSERT
updated to reflect that the logic is valid for ARMv8-R.

3) 2 build attribute merging tests are added to test the first change.

=== Context ===

This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to add support for ARMv8-R in GAS:
instructions, build attributes and readelf.

=== Patch description ===

Although some differences exist for system registers, from GAS point of
view ARMv8-R supports the same instructions as ARMv8-A Aarch32 state
and a subset of its extensions. This patch therefore introduce a new
feature bit to distinguish the availability of the pan, ras and rdma
extensions between ARMv8-A and ARMv8-R and allow crypto, fp and simd
extensions to be used by ARMv8-R.

Most of the changes are then in the testsuite to (i) rename source files
and error output to be shared between ARMv8-A and ARMv8-R, (ii) rename
files with expected output for ARMv8-A build attributes and (iii) add
new files with expected output for ARMv8-R build attributes.

7 years ago[ARM] Remove ARMv6S-M special casing
Thomas Preud'homme [Sat, 24 Jun 2017 09:26:41 +0000 (10:26 +0100)]
[ARM] Remove ARMv6S-M special casing

=== Context ===

This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to remove special casing for ARMv6S-M
autodetection.

=== Motivation ===

Currently, SWI and SVC mnemonics are enabled for ARMv4T and successor
architectures with extra checks in the handler function (do_t_swi) to
give an error message when ARMv6-M is targeted and some more special
casing in aeabi_set_public_attributes. This was made to exclude these
mnemonics for ARMv6-M unless the OS extension is in use.

However this logic is superfluous: there is already code to check
whether an instruction is available based on the feature bit it is part
of and whether the targeted architecture has that feature bit. This
patch aims at removing that unneeded complexity.

=== Patch description ===

The OS extension is already limited to the ARMv6-M architecture so all
this patch does is redefined availability of the ARM_EXT_OS feature bit
to not be present for ARM_ARCH_V6M. ARM_ARCH_V6SM does not need any
change either because it already includes ARM_EXT_OS.

The patch also make sure that the error message that was given by
do_t_swi when SWI/SVC is unavailable is still the same by detecting the
situation in md_assemble.

To support IBT in Intel Control-flow Enforcement Technology (CET)
instructions:

https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf

 #define GNU_PROPERTY_X86_FEATURE_1_AND 0xc0000002

 #define GNU_PROPERTY_X86_FEATURE_1_IBT (1U << 0)

are added to GNU program properties to indicate that all executable
sections are compatible with IBT when ENDBR instruction starts each
valid target where an indirect branch instruction can land.

GNU_PROPERTY_X86_FEATURE_1_IBT is set on output only if it is set on
all relocatable inputs.

The followings changes are made to the Procedure Linkage Table (PLT):

1. For 64-bit x86-64,  PLT is changed to

PLT0:  push       GOT[1]
       bnd jmp    *GOT[2]
       nop
...
PLTn:  endbr64
       push       namen_reloc_index
       bnd jmp    PLT0

together with the second PLT section:

PLTn:  endbr64
       bnd jmp   *GOT[namen_index]
       nop

BND prefix is also added so that IBT-enabled PLT is compatible with MPX.

2. For 32-bit x86-64 (x32) and i386,  PLT is changed to

PLT0:  push       GOT[1]
       jmp        *GOT[2]
       nop
...
PLTn:  endbr64                                 # endbr32 for i386.
       push       namen_reloc_index
       jmp        PLT0

together with the second PLT section:

PLTn:  endbr64                                 # endbr32 for i386.
       jmp       *GOT[namen_index]
       nop

BND prefix isn't used since MPX isn't supported on x32 and BND registers
aren't used in parameter passing on i386.

GOT is an array of addresses.  Initially, GOT[namen_index] is filled
with the address of the ENDBR instruction of the corresponding entry
in the first PLT section.  The function, namen, is called via the
ENDBR instruction in the second PLT entry.  GOT[namen_index] is updated
to the actual address of the function, namen, at run-time.

2 linker command line options are added:

1. -z ibtplt: Generate IBT-enabled PLT.
2. -z ibt: Generate GNU_PROPERTY_X86_FEATURE_1_IBT in GNU program
properties as well as IBT-enabled PLT.

environ-selftests: Ignore -Wself-move warning

clang gives this warning:

 ..../gdb/unittests/environ-selftests.c:139:7: error: explicitly moving variable of type 'gdb_environ' to itself [-Werror,-Wself-move]
   env = std::move (env);
   ~~~ ^            ~~~

Ignoring the warning locally is the right thing to do, since it warns
about behavior we want to unit test, while an explicit self-move in
real code would likely be a mistake that we'd want to catch.

To avoid cluttering the code with preprocessor conditionals, this
commit adds the file common/diagnostics.h, in which we can put macros
used to control compiler diagnostics.
