Owen Anderson f02d98d7c0 Add support for parsing #-0 on non-memory-operand immediate values, and add a testcase that necessitates it.

Duncan Sands 4d63542b82 Fix PR5329: pay attention to constructor/destructor priority 
when outputting them.  With this, the entire LLVM testsuite
passes when built with dragonegg.

 2011-08-26 21:11:23 +00:00
Owen Anderson 16d33f36d5 invalid-LDR_PRE-arm.txt was already passing, but for the wrong reasons. We were failing to specify enough fixed bits of LDR_PRE/LDRB_PRE, resulting in decoding conflicts. Separate them into immediate vs. register versions, allowing us to specify the necessary fixed bits. This in turn results in the test being decoded properly, and being rejected as UNPREDICTABLE rather than a hard failure.

Eli Friedman 452aae6202 Atomic load/store on ARM/Thumb. 
I don't really like the patterns, but I'm having trouble coming up with a
better way to handle them.

I plan on making other targets use the same legalization
ARM-without-memory-barriers is using... it's not especially efficient, but
if anyone cares, it's not that hard to fix for a given target if there's
some better lowering.

Benjamin Kramer fb212a6309 SimplifyCFG: If we have a PHI node that can evaluate to NULL and do a load or store to the address returned by the PHI node then we can consider this incoming value as dead and remove the edge pointing there, unless there are instructions that can affect control flow executed in between. 
In theory this could be extended to other instructions, eg. division by zero, but it's likely that it will "miscompile" some code because people depend on div by zero not trapping. NULL pointer dereference usually leads to a crash so we should be on the safe side.

This shrinks the size of a Release clang by 16k on x86_64.

Evan Cheng eee864520c Some autoconf tests use module level inline asm to test compiler's handling of 
.cfi_startproc. e.g. libffi:

 $ cat confopt.c 
asm (".cfi_startproc\n\t.cfi_endproc");

int main () { return 0; }

Teach MC / dwarf emission to handle these cfi directives which essentially
create an empty frame.

Bruno Cardoso Lopes 2a3ffb5d97 Introduce a pass to insert vzeroupper instructions to avoid AVX to 
SSE transition penalty. The pass is enabled through the "x86-use-vzeroupper"
llc command line option. This is only the first step (very naive and
conservative one) to sketch out the idea, but proper DFA is coming next
to allow smarter decisions. Comments and ideas now and in further commits
will be very appreciated.

Bruno Cardoso Lopes be5e987379 Introduce matching patterns for vbroadcast AVX instruction. The idea is to 
match splats in the form (splat (scalar_to_vector (load ...))) whenever
the load can be folded. All the logic and instruction emission is
working but because of PR8156, there are no ways to match loads, cause
they can never be folded for splats. Thus, the tests are XFAILed, but
I've tested and exercised all the logic using a relaxed version for
checking the foldable loads, as if the bug was already fixed. This
should work out of the box once PR8156 gets fixed since MayFoldLoad will
work as expected.

vinsertf128 $1 + vpermilps $0, remove the old code that used to first

This is better because the handling code gets simpler and also makes a
better room for the upcoming vbroadcast!

Thumb one requires that many arithmetic instruction forms have an 'S'

on whether the instruction is in an IT block. Use target parser predicates
to check for these sorts of context-sensitive constraints.

Bruno Cardoso Lopes 2e99f1b3aa Instead of always leaving the work to the generic legalizer when 
there is no support for native 256-bit shuffles, be more smart in some
cases, for example, when you can extract specific 128-bit parts and use
regular 128-bit shuffles for them. Example:

For this shuffle:
  shufflevector <4 x i64> %a, <4 x i64> %b, <4 x i32>
                <i32 1, i32 0, i32 7, i32 6>

This was expanded to:
  vextractf128  $1, %ymm1, %xmm2
  vpextrq $0, %xmm2, %rax
  vmovd %rax, %xmm1
  vpextrq $1, %xmm2, %rax
  vmovd %rax, %xmm2
  vpunpcklqdq %xmm1, %xmm2, %xmm1
  vpextrq $0, %xmm0, %rax
  vmovd %rax, %xmm2
  vpextrq $1, %xmm0, %rax
  vmovd %rax, %xmm0
  vpunpcklqdq %xmm2, %xmm0, %xmm0
  vinsertf128 $1, %xmm1, %ymm0, %ymm0
  ret

Now we get:
  vshufpd $1, %xmm0, %xmm0, %xmm0
  vextractf128  $1, %ymm1, %xmm1
  vshufpd $1, %xmm1, %xmm1, %xmm1

Akira Hatanaka 2263c10946 Fix handling of double precision loads and stores when Mips1 is targeted. 
Mips1 does not support double precision loads or stores, therefore two single
precision loads or stores must be used in place of these instructions. This 
patch treats double precision loads and stores as if they are legal
instructions until MCInstLowering, instead of generating the single precision
instructions during instruction selection or Prolog/Epilog code insertion.

Without the changes made in this patch, llc produces code that has the same 
problem described in r137484 or bails out when
MipsInstrInfo::storeRegToStackSlot or loadRegFromStackSlot is called before
register allocation.
