Dylan Noblesmith f490726633 CppBackend: fixup for api change 
This broke after r133364.

llvm-svn: 133709
 2011-06-23 12:11:37 +00:00
Jay Foad 61ea0e4692 Reinstate r133513 (reverted in r133700) with an additional fix for a 
-Wshorten-64-to-32 warning in Instructions.h.

Eric Christopher 96513120b7 Revert r133513: 
"Reinstate r133435 and r133449 (reverted in r133499) now that the clang
self-hosted build failure has been fixed (r133512)."

Due to some additional warnings.

Bill Wendling 9af2fa9d1b Use the presence of the __compact_unwind section to indicate that a target 
supports compact unwind info instead of having a separate flag indicating this.

llvm-svn: 133685
 2011-06-23 05:13:28 +00:00
Rafael Espindola e25a8710e5 Move more logic to shouldTailDuplicate and only duplicate regular bb before 
register allocation if it has a indirectbr or if we can duplicate it to
every predecessor.

This fixes the SingleSource/Benchmarks/Shootout-C++/matrix.cpp regression but
keeps the previous improvements to sunspider.

Evan Cheng ee9b90a727 Get rid of one getStackAlignment(). RegisterInfo shouldn't need to know about stack alignment. 
llvm-svn: 133679
 2011-06-23 01:53:43 +00:00
Bill Wendling e8fc92ad46 Some skeleton code to emit the compact unwind. If the information is unable to 
be emitted in a compact way, we then default to emitting a CIE and FDE.

Bill Wendling f942585dae Add a flag that indicates whether a target supports compact unwind info or not. 
llvm-svn: 133662
 2011-06-22 23:16:51 +00:00
Rafael Espindola 2496c1f1f8 Reenable tail duplication of bb with just an unconditional jump, but 
don't remove blocks that have their address taken.

llvm-svn: 133659
 2011-06-22 22:31:57 +00:00
Bill Wendling d346304373 Add a __LD,__compact_unwind section. 
If the linker supports it, this will hold the CIE and FDE information in a
compact format. The implementation of the compact unwinding emission is coming
soon.

Chad Rosier cb7cfa4954 Revert r133607. This is causing failures in the Clang gccTestSuite. 
Specifically, gcc.c-torture/compile/pr21356.c.

 2011-06-22 21:13:23 +00:00
Bill Wendling eb872e0471 Move class methods out-of-line. This reduces the indentation, and is more in 
line with LLVM's general coding style.
No functionality change.

is larger than the sum of the elements (including per-element padding).

llvm-svn: 133612
 2011-06-22 08:55:11 +00:00
Jay Foad c365eeaea6 Extend ConstantUniqueMap with a new template parameter ValRefType, 
representing a constant reference to ValType. Normally this is just
"const ValType &", but when ValType is a std::vector we want to use
ArrayRef as the reference type.

Rafael Espindola 0850f709de Reenable the optimization added in 133415, but change the definition of a "simple" bb to 
be one with only one unconditional branch and no phis. Duplicating the phis in this case
is possible, but requeres liveness analysis or breaking edges.

Nick Lewycky ef9c497e4c Add support for assembling "movq" when it's correct to do so, while continuing 
to emit "movd" across the board to continue supporting a Darwin assembler bug.
This is the reincarnation of r133452.

Bob Wilson 646dd0f4d1 Revert r133452: "Emit movq for 64-bit register to XMM register moves..." 
This is breaking compiler-rt and llvm-gcc builds on MacOSX when not using
the integrated assembler.

Jay Foad a97a2c998e Reinstate r133435 and r133449 (reverted in r133499) now that the clang 
self-hosted build failure has been fixed (r133512).

Jay Foad 25127ab1e4 Don't use PN->replaceUsesOfWith() to change a PHINode's incoming blocks, 
because it won't work after my phi operand changes, because the incoming
blocks will no longer be Uses.

Evan Cheng 4c0bd9629d Teach dag combine to match halfword byteswap patterns. 
1. (((x) & 0xFF00) >> 8) | (((x) & 0x00FF) << 8)
   => (bswap x) >> 16
2. ((x&0xff)<<8)|((x&0xff00)>>8)|((x&0xff000000)>>8)|((x&0x00ff0000)<<8))
   => (rotl (bswap x) 16)

This allows us to eliminate most of the def : Pat patterns for ARM rev16
revsh instructions. It catches many more cases for ARM and x86.

Andrew Trick 69d4452f2e indvars -disable-iv-rewrite: Adds support for eliminating identity 
ops.

This is a rewrite of the IV simplification algorithm used by
-disable-iv-rewrite. To avoid perturbing the default mode, I
temporarily split the driver and created SimplifyIVUsersNoRewrite. The
idea is to avoid doing opcode/pattern matching inside
IndVarSimplify. SCEV already does it. We want to optimize with the
full generality of SCEV, but optimize def-use chains top down on-demand rather
than rewriting the entire expression bottom-up. This was easy to do
for operations that SCEV can prove are identity function. So we're now
eliminating bitmasks and zero extends this way.

A result of this rewrite is that indvars -disable-iv-rewrite no longer
requires IVUsers.
