At least on x86_64 with testsuite in -m32 (expecting native i386 would be the
same).

Pedro Alves:

The difference is that with newer GCC there's an extra instruction
after the call which is still assigned to line 583:

I don't know why -m32 changed to push/add instead of mov while 64-bit hasn't.

This is most likely needed on non-x86 ports as well.

So I have reverted it and just simplified the comment.

The third case is not necessary during testing but I have changed back all the
3 cases.

Mike Frysinger ce39bd3890 sim: move many common settings from CPPFLAGS to config.h
Rather than stuffing the command line with a bunch of -D flags, start
moving things to config.h which is managed by autoheader.  This makes
the makefile a bit simpler and the build output tighter, and it makes
the migration to automake easier as there are fewer vars to juggle.

We'll want to move the other options out too, but it'll take more work.

Mike Frysinger e19418e02e sim: drop unused SIM_AC_OPTION_PACKAGES
This was imported from the ppc sim, but that was only used to control
a single file, and that is already governed by the hw models.  There's
no need to have a sep configure option here, especially since none of
the other sims are using it.  Even when the code is enabled, there's
no runtime overhead.

Mike Frysinger 16f7876d71 sim: allow the environment configure option everywhere
Currently ports have to call SIM_AC_OPTION_ENVIRONMENT explicitly in
order to make the configure flag available.  There's no real reason
to not allow this flag for all ports, so move it to the common sim
macro.  This way we get standard behavior across all ports too.
2016-01-10 17:03:36 -05:00
Mike Frysinger 35656e9521 sim: allow the assert configure option everywhere
Currently ports have to call SIM_AC_OPTION_ASSERT explicitly in order
to make the configure flag available, which none of them do.  There's
no real reason to not allow this flag for all ports, so move it to the
common sim macro.  This way we get standard behavior across all ports.
2016-01-10 16:13:13 -05:00
Mike Frysinger 99d8e87993 sim: drop targ-vals.def->nltvals.def indirection
We don't have alternative nltvals.def files, so always symlinking
the targ-vals.def file to it doesn't gain us anything.  It does
make the build more complicated though and a pain to convert to
something newer (like automake).  Drop the symlinking entirely.

In the future, we'll want to explode this file anyways into the
respective arch dirs so things can be selected dynamically at
runtime, so it's not like we'll be bringing this back.

Mike Frysinger 6d90347b5d sim: mips: drop SIM_AC_OPTION_SMP call
No other port calls this macro directly, and mips has it hardcoded
to the default -- disabling smp.  In the future we'll enable this
for all targets in common code, so tidy up the mips code now.
2016-01-10 03:42:06 -05:00
Mike Frysinger 347fe5bb86 sim: allow the inline configure option everywhere
Currently ports have to call SIM_AC_OPTION_INLINE explicitly in order

allow this flag for all ports, so move it to the common sim macro.
This way we get standard behavior across all ports too.
2016-01-10 03:36:32 -05:00
Mike Frysinger 0dc73ef7c3 sim: drop --enable-sim-{regparm,stdcall} options
These options were never exposed for most sims (just the ppc one),
and they are really only useful on 32-bit x86 systems.  Considering
modern systems tend to be 64-bit x86_64 and how well modern compilers
are at optimizing code, these have outlived their usefulness.
2016-01-10 03:15:01 -05:00
Mike Frysinger 22be3fbeac sim: drop --enable-sim-cflags option
No other sub directory provides such a configuration option, so
drop it from the sim dir as well.  This cleans up a good bit of
code in the process.

If people want to use custom flags for just the sim, they can
still run configure+make by hand in the sim subdir and use the
normal CFLAGS settings.

Mike Frysinger 5295724cdc sim: stop configuring common subdir
Now that cconfig.h doesn't exist, there's no need to build in the common
subdir anymore.  We leave the configure/Makefile files in there as there
is a helper for developers to generate the nltvals.def file.  Once that
gets cleaned up in the future though, we can drop the build logic too.
2016-01-09 03:52:30 -05:00
Mike Frysinger 936df7568a sim: drop common/cconfig.h in favor of a single config.h
The common subdir sets up a cconfig.h file to hold checks for the common
code.  In practice, most files still end up using config.h instead which
just leads to confusion.

Merge all the configure checks that went into cconfig.h into SIM_AC_COMMON
so we can drop the cconfig.h file altogether.  Now there is only a single
config.h file like normal.

Simon Marchi 582a1b0064 perf testsuite: python 3 fixes
There are a few errors when trying to run the performance testsuite with
Python 3.  This commit fixes them.

In Python 2, it was possible to use relative imports (importing a module
relative to the current one).  In Python 3 it isn't.  So I use
absolute_import from the __future__ module, which allows Python 2 to
behave like Python 3, and use the Python 3 syntax.

In Python 3, dict.iterkeys doesn't exist anymore.  Using dict.keys is a
good compromise in this case.

gdb/testsuite/ChangeLog:

	* gdb.perf/lib/perftest/perftest.py: Change relative imports to
	absolute.
	(SingleStatisticTestResult.report): Use dict.keys instead of
	dict.iterkeys.

In the test, the program is being single-stepped for software watchpoint,
and in each internal stop, python unwinder sniffer is used,

when GDB goes to python extension, or other language extension, the
SIGINT handler is changed, and is restored when GDB leaves extension
language.  GDB only stays in extension language for a very short period
in this case, but if ctrl-c is pressed at that moment, python extension
will handle the SIGINT, and exceptions.KeyboardInterrupt is shown.

Language extension is used in GDB side rather than inferior side,
so GDB should only change SIGINT handler for extension language when
the terminal is ours (not inferior's).  This is what this patch does.
With this patch applied, I run random-signal.exp in a loop for 18
hours, and no fail is shown.

Yao Qi 5a0dd67a45 Check input interrupt first when reading packet
Hi,
I see timeout in one of several runs of random-signal.exp like this,

 $ (set -e; while true; do make check RUNTESTFLAGS="--target_board=native-gdbserver random-signal.exp"; done)

In about every five runs, we can see a fail,

^CFAIL: gdb.base/random-signal.exp: stop with control-c (timeout)

after some investigation, I find '\003' may be discarded by GDBserver when
it is expecting '$'.  In GDB side, both normal packets and '\003' are sent
via function send, but GDBserver may receive them at any time, that is to
say, in the receive buffer in GDBserver, '\003' may appear before or after
normal packet.  However, current GDBserver doesn't handle this case.

With this patch applied, I don't see this fail in multiple runs.
Although there is still timeout fail, that is a different problem, the
next patch will fix it.

by simply moving these macros and variables to

Andrew Burgess b05a65d0ad bfd/arc: Add R_ prefix to all relocation names
The convention within for relocation names is that they start with the
string "R_", however, this is not so for ARC for the display names of
relocations, however, internally, the names for the relocations types do
have the 'R_' prefix.  I suspect that the missing 'R_' on the output
strings was an oversight, as I can't see any comment to the contrary.

To bring ARC into line with other targets, this commit adds the 'R_'
prefix to the output strings used for relocation names, and updates all
of the assembler tests where this was exposed.

bfd/ChangeLog:

	* elf32-arc.c (reloc_type_to_name): Change ARC_RELOC_HOWTO to
	place 'R_' before the reloc name returned.
	(elf_arc_howto_table): Change ARC_RELOC_HOWTO to place 'R_' before
	the relocation string.

Mike Frysinger b36c1ccb1f libiberty: {count,dup,write}argv: constify argv input slightly
Would be more useful if we could use "const char * const *", but there's
a long standing bug where gcc warns about incompatible pointers when you
try to pass in "char **".  We can at least constify the array itself as
gcc will not warn in that case.

Patrick Palka 4bec0ef03e libiberty: Tweak the documentation of libiberty's xcrc32 function
In some places the xcrc32 documentation refers to GDB's own crc32
implementation, but GDB no longer has its own crc32 implementation.
It now uses libiberty's xcrc32 throughout.  So this patch removes
these references to GDB's now-nonexistent crc32 implementation.

Also, there appears to be a bug in the table-generation program embedded
within the documentation.  When the variable "int i" is >= 128, the
computation "i << 24" shifts a one bit into the sign bit (assuming a
32-bit int), which is UB.  To avoid this UB, I think it is sufficient to
make the induction variables i and j have type unsigned int.  This bug
seems latent, however.  I ran the program before and after this change
and the table output is the same.

Nick Clifton 13b356b2b5 libiberty: fix warnings about left shifting a negative value.
GCC PR 66827 reports some problems with left shifting a negative
  value:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66827

  Of the problems reported only two remain - in libiberty/regex.c:

libiberty/regex.c:6970:11: runtime error: left shift of negative value -1
libiberty/regex.c:7165:4: runtime error: left shift of negative value -1

  The patch below fixes these errors by casting the value to be shifted
  to unsigned before the shift occurs.

  No regressions were found in the libiberty testsuite or bootstrapping
  gcc (on an x86_64 target).

There has never been a GNU/sim port for the S+Core architecture.
It was added to support private code that has (and most likely
never will) see the light of day [1].  Punt this as we don't do
this for other people.  If you want to maintain a proprietary
internal build, then that's not really our problem.
