2012-08-23Simplify the computeOperandLatency API.Andrew Trick
The logic for recomputing latency based on a ScheduleDAG edge was shady. This bypasses the problem by requiring the client to provide operand indices. This ensures consistent use of the machine model's API. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162420 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-23Make function loadImmediate a member of MipsSEInstrInfo and change it to returnAkira Hatanaka
the temporary register that was used to load the immediate. Currently, it always returns register $at, but this will change if, in the future, we decide to use another register. No changes in functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162417 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-22Print out the location of expanded multiclass defs in TableGen errors.Jakob Stoklund Olesen
When reporting an error for a defm, we would previously only report the location of the outer defm, which is not always where the error is. Now we also print the location of the expanded multiclass defs: lib/Target/X86/X86InstrSSE.td:2902:12: error: foo defm ADD : basic_sse12_fp_binop_s<0x58, "add", fadd, SSE_ALU_ITINS_S>, ^ lib/Target/X86/X86InstrSSE.td:2801:11: note: instantiated from multiclass defm PD : sse12_fp_packed<opc, !strconcat(OpcodeStr, "pd"), OpNode, VR128, ^ lib/Target/X86/X86InstrSSE.td:194:5: note: instantiated from multiclass def rm : PI<opc, MRMSrcMem, (outs RC:$dst), (ins RC:$src1, x86memop:$src2), ^ git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162409 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-22SimplifyLibCalls: Give all safely-shrinkable libcalls the same treatment.Benjamin Kramer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162383 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-22[ms-inline asm] Avoid a false positive assertionChad Rosier
Assertion failed: (Start.isValid() == End.isValid() && "Start and end should either both be valid or both be invalid!") when parsing inline asm. SMLoc assumes that the first char * in the source is invalid. However, when parsing an inline asm the mnemonic is at this location. I don't want to change SMLoc, so use a trivial workaround. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162381 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-22Add a few float shrinking optimizations to SimplifyLibCalls. UnsafeChad Rosier
optimizations are guarded by the -enable-double-float-shrink LLVM option. Last bit of PR13574. Patch by Weiming Zhao <weimingz@codeaurora.org>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162368 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-22Tidy up a few more uses of MF.getFunction()->getName().David Blaikie
Based on CR feedback from r162301 and Craig Topper's refactoring in r162347 here are a few other places that could use the same API (& in one instance drop a Function.h dependency). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162367 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-22Add a getName function to MachineFunction. Use it in places that previously ↵Craig Topper
did getFunction()->getName(). Remove includes of Function.h that are no longer needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162347 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-22Add register Mips::GP to the list of reserved registers if target is bare-metalAkira Hatanaka
to prevent it from being clobbered. mips uses $gp to access small data section. This bug was originally reported by Carl Norum. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162340 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-22Add option disable-mips-delay-filler. Turn on mips' delay slot filler byAkira Hatanaka
default. Patch by Carl Norum. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162339 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-22For mips64 switch statements in subroutines could generate Jack Carter
within the codegen EK_GPRel64BlockAddress. This was not supported for direct object output and resulted in an assertion. This change adds support for EK_GPRel64BlockAddress for direct object. One fallout from this is to turn on rela relocations for mips64 to match gas. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162334 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-22Initialize SelectionDAGBuilder's Context in 'init', not in its constructor. TheRichard Smith
SelectionDAG's 'init' has not been called when the SelectionDAGBuilder is constructed (in SelectionDAGISel's constructor), so this was previously always initialized with 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162333 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-22Reduce alignment of SmallVector<T> to the required amount, rather than ↵Richard Smith
forcing 16-byte alignment. This fixes misaligned SmallVector accesses via ExtractValueInst's SmallVector data member. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162331 91177308-0d34-0410-b5e6-96231b3b80d8

no cost to using memcpy here: the fixed code is optimized by LLVM to perfect machine code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162311 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-21[ms-inline asm] Do not report a Parser error when matching inline assembly.Chad Rosier
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162306 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-21Remove unnecessary cast that was also unnecessarily casting away constness.David Blaikie
Even looking at the revision history I couldn't quite piece together why this cast was ever written in the first place, but I assume it was because of some change in the inheritance, perhaps this function was reimplemented in a derived type & this caller was meant to get the base version (& it wasn't virtual)? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162301 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-21Fix macros arguments with an underscore, dot or dollar in them. This is basedRafael Espindola
on a patch by Andy/PaX. I added the support for dot and dollar. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162298 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-21[ms-inline asm] Expose the ErrorInfo from the MatchInstructionImpl. In general,Chad Rosier
this is the index of the operand that failed to match. Note: This may cause a buildbot failure due to an API mismatch in clang. Should recover with my next commit to clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162295 91177308-0d34-0410-b5e6-96231b3b80d8

consistent with the other "expected identifier" errors. Extracted from the Andy/PaX patch. I added the test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162291 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-21MCJIT: Tidy up the constructor.Jim Grosbach
The MCJIT doesn't need or want a TargetJITInfo. That's vestigal from the old JIT, so just remove it. rdar://12119347 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162280 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-21Port the global copy optimization from the SROA pass to InstCombine.Chandler Carruth
This optimization is really just replacing allocas wholesale with globals, there is no scalarization. The underlying motivation for this patch is to simplify the SROA pass and focus it on splitting and promoting allocas. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162271 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-20Fix a quadratic algorithm in MachineBranchProbabilityInfo.Jakob Stoklund Olesen
The getSumForBlock function was quadratic in the number of successors because getSuccWeight would perform a linear search for an already known iterator. This patch was originally committed as r161460, but reverted again because of assertion failures. Now that duplicate Machine CFG edges have been eliminated, this works properly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162233 91177308-0d34-0410-b5e6-96231b3b80d8
