Andrew Burgess 62bdf2d66e ld/testing: Fix error and warning checks in run_dump_test
The options warning_output and error_output to the run_dump_test
function were incorrectly checking the return value from the regexp_diff
function, and so, as a result failing tests were showing as a pass.
Fixed in this commit.

	* testsuite/lib/ld-lib.exp (run_dump_test): Fix check of return
	value from regexp_diff.

Yao Qi fb3f3d25c3 Check func against 0 rather than NULL
Variable 'func''s type is CORE_ADDR, so it should be compared with 0
rather than NULL.  This causes a build error.

This patch fixes this.

Yao Qi 779aa56f2c Add arm epilogue unwinder
Nowadays, GDB can't unwind successfully from epilogue on arm,

 (gdb) bt
 #0  0x76ff65a2 in shr1 () from /home/yao/Source/gnu/build/gdb/testsuite/gdb.reverse/shr1.sl
 #1  0x0000869e in main () at /home/yao/Source/gnu/build/gdb/testsuite/../../../binutils-gdb/gdb/testsuite/gdb.reverse/solib-reverse.c:34
 Backtrace stopped: previous frame inner to this frame (corrupt stack?)

(gdb) disassemble shr1
Dump of assembler code for function shr1:
   ....
   0x76ff659a <+10>:	adds	r7, #12
   0x76ff659c <+12>:	mov	sp, r7
   0x76ff659e <+14>:	ldr.w	r7, [sp], #4
   0x76ff65a2 <+18>:	bx	lr
End of assembler dump.

in this case, prologue unwinder is used.  It analyzes the prologue and
get the offsets of saved registers to SP.  However, in epilogue, the
SP has been restored, prologue unwinder gets the registers from the
wrong address, and even the frame id is wrong.

In reverse debugging, this case (program stops at the last instruction
of function) happens quite frequently due to the reverse execution.
There are many test fails due to missing epilogue unwinder.

This adds epilogue unwinder, but the frame cache is still get by
prologue unwinder except that SP is fixed up separately, because SP
is restored in epilogue.

This patch fixes many fails in solib-precsave.exp, and solib-reverse.exp.

Yao Qi c58b006a7e Refactor arm_stack_frame_destroyed_p
This patch is to refactor arm_stack_frame_destroyed_p, so that the code
can be used in both arm_stack_frame_destroyed_p and arm epilogue
unwinder I am going to add in the next patch.  In fact, the code
is the same in two places, but checking whether it is thumb mode
is slightly different.  arm_stack_frame_destroyed_p uses
arm_pc_is_thumb, and epilogue unwinder should use arm_frame_is_thumb.

Yao Qi e6359af3fd Simplify gdb.reverse/until-reverse.c
Nowadays, functions fprintf, printf and malloc are executed in
gdb.reverse/until-reverse.c, so that it takes much time to record
instructions inside them.  This may cause timeout, and we had several

however, I can't figure out how these functions (fprintf, printf and
malloc) are related to the test itself.  marker1 is a function from
shared library too so we don't need these complicated libc functions
at all.  IMO, recording the instructions in these libc functions has
nothing to do with the test itself except slow down the test.  This
patch is to remove the usage of fprintf and printf, and also move
malloc to a dead code path.

Marcin Kościelnicki 28170b88cc gdbserver: Handle 'v' packet while processing qSymbol.
On powerpc64, qSymbol query may require gdb to read a function
descriptor, sending a vFile packet to gdbserver.  Thus, we need
to handle 'v' packet in look_up_one_symbol.

vFile replies may be quite long, and require reallocating own_buf.
Since handle_v_requests assumes the buffer is the static global own_buf
from server.c and reallocates it, we need to make own_buf global and
use it from look_up_one_symbol instead of using our own auto variable.
I've also done the same change in relocate_instruction, just in case.

On gdb side, in remote_check_symbols, rs->buf may be clobbered by vFile
handling, yet we need its contents for the reply (the symbol name is
stored there).  Allocate a new buffer instead.

This broke fast tracepoints on powerpc64, due to errors in reading IPA
symbols.

	* remote.c (remote_check_symbols): Allocate own buffer for reply.

gdbserver/ChangeLog:

	* remote-utils.c (look_up_one_symbol): Remove own_buf, handle 'v'

	(handle_v_requests): Make global.

Marcin Kościelnicki abd9baf9c6 gdbserver/s390: Add fast tracepoint support.
Fast tracepoints will only work on 6-byte intructions, and assume at least
a z900 CPU.  s390 also has 4-byte jump instructions, which also work on
pre-z900, but their range is limitted to +-64kiB, which is not very useful
(and wouldn't work at all with current jump pad allocation).

There's a little problem with s390_relocate_instruction function: it
converts BRAS/BRASL instructions to LARL of the return address + JG
to the target address.  On 31-bit, this sets the high bit of the target
register to 0, while BRAS/BRASL would set it to 1.  While this is not
a problem when the result is only used to address memory, it could
possibly break something that expects to compare such addresses for
equality without first masking the bit off.  In particular, I'm not sure
whether leaving the return address high bit unset is ABI-compliant
(could confuse some unwinder?).  If that's a problem, it could be fixed
by handling it in the jump pad (since at that point we can just modify
the GPRs in the save area without having to worry about preserving
CCs and only having that one GPR to work with - I'm not sure if it's
even possible to set the high bit with such constraints).

Trevor Saunders 17b9d67d4e make md_parse_option () take a const char *
This is mostly just adding const in many places, however there are a couple
interesting things.  We need to add casts in tc-s390.c and tc-cris.c because
they have functions that assign to input_line_pointer an argument that
sometimes comes from md_parse_option.  Presumably this is safe because those
targets never pass literals to md_parse_option (), but this code should
probably be improved in the future.  Also xtensa passes the argument to strtoll
which is a rather odd function, it takes a const char * as argument and returns
a pointer into that string as a char * through an out argument, but we can work
around that by adding more variables.

Jose E. Marchesi f65c3d1b26 gas: sparc: allow ASR registers in the 0..31 range in V9 and later
In the SPARC V9 (and later) versions of the SPARC specification, the
section C.1.1 "Register Names" specifies that:

"asr_reg.  An asr_reg is an Ancillary State Register name.  It may have
 one of the following values:

  %asr16-%asr31"

The rationale of having this restriction was that the registers from 16
to 31 are reserved to implementations, and are therefore "non-V9".  It
also assumes that the existing ASR registers in the range 0..31 will
have their own names such as %y, that can be used to access such
registers.

However, this is problematic.  When a new ASR register is introduced,
such as %mcdper a.k.a. %asr14, it is useful to be able to use %asr14 in
order to not depend on the latest version of the assembler.

The Solaris assembler is lax and allows to assembly instructions
referring to %asr0 to %asr31.  This patch makes the GNU assembler to
mimic that behavior.

  2016-03-24  Jose E. Marchesi  <jose.marchesi@oracle.com>

right diagnostics when an invalid %asrN register is used in an

Trevor Saunders e742e119e1 make microblaze build with -Wwrite-strings
frag_var () assigns its last argument to frag::fr_opcode, and it turns out
some targets modify the string that points to.  However it appears niether the
generic code or the microblaze code modifies what fr_opcode points to, so this
code should be safe.  So we unfortunately need to cast to char * when passing
an argument to frag_var () but otherwise microblaze can itself point to these
strings with const char *.
