2012-11-30Aggregate pass execution time report by pass ID instead of pass instance.Jakob Stoklund Olesen
This avoids unidentified duplicates in the pass execution time report when a pass runs more than once in the pass manager pipeline. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169039 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-30Codegen failure for vmull with small vectorsSebastian Pop
Codegen was failing with an assertion because of unexpected vector operands when legalizing the selection DAG for a MUL instruction. The asserting code was legalizing multiplies for vectors of size 128 bits. It uses a custom lowering to try and detect cases where it can use a VMULL instruction instead of a VMOVL + VMUL. The code was looking for input operands to the MUL that had been sign or zero extended. If it found the extended operands it would drop the sign/zero extension and use the original vector size as input to a VMULL instruction. The code assumed that the original input vector was 64 bits so that after dropping the extension it would fit directly into a D register and could be used as an operand of a VMULL instruction. The input code that trigger the failure used a vector of <4 x i8> that was sign extended to <4 x i32>. It was not safe to drop the sign extension in this case because the original vector is only 32 bits wide. The fix is to insert a sign extension for the vector to reach the required 64 bit size. In this particular example, the vector would need to be sign extented to a <4 x i16>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169024 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-30This patch fixes the Altivec addend construction for the fused multiply-addAdhemerval Zanella
instruction (vmaddfp) to conform with IEEE to ensure the sign of a zero result when resulting product is -0.0. The -0.0 vector addend to vmaddfp is generated by a creating a vector with full bits sets and then shifting each elements by 31-bits to the left, resulting in a vector of 0x80000000 (or -0.0 as float). The 'buildvec_canonicalize.ll' was adjusted to reflect this change and the 'vec_mul.ll' was complemented with the float vector multiplication test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168998 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-30Switch LLVM_USE_RVALUE_REFERENCES to LLVM_HAS_RVALUE_REFERENCES.Chandler Carruth
Rationale: 1) This was the name in the comment block. ;] 2) It matches Clang's __has_feature naming convention. 3) It matches other compiler-feature-test conventions. Sorry for the noise. =] I've also switch the comment block to use a \brief tag and not duplicate the name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168996 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-30Separate out the tests for whether the compiler suports R-valueChandler Carruth
references from whether it supports an R-value reference *this. No version of GCC today supports the latter, which breaks GCC C++11 compiles of LLVM and Clang now. Also add doxygen comments clarifying what's going on here, and update the usage in Optional. I'll update the usages in Clang next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168993 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-30More strict error checking in parseSpecifier + simplified code.Patrik Hagglund
For example, don't allow empty strings to be passed to getInt. Move asserts inside parseSpecifier. (One day we may want to pass parse error messages to the user - from LLParser - instead of using asserts, but keep the code simple until then. There have been an attempt to do this. See r142288, which got reverted, and r142605.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168991 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-30Fix non-determinism introduced in r168970 and pointed out by Duncan.Chandler Carruth
We're iterating over a non-deterministically ordered container looking for two saturating flags. To do this correctly, we have to saturate both, and only stop looping if both saturate to their final value. Otherwise, which flag we see first changes the result. This is also a micro-optimization of the previous version as now we don't go into the (possibly expensive) test logic once the first violation of either constraint is detected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168989 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-30Rearrange the comments, control flow, and variable names; noChandler Carruth
functionality changed. Evan's commit r168970 moved the code that the primary comment in this function referred to to the other end of the function without moving the comment, and there has been a steady creep of "boolean" logic in it that is simpler if handled via early exit. That way each special case can have its own comments. I've also made the variable name a bit more explanatory than "AllFit". This is in preparation to fix the non-deterministic output of this function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168988 91177308-0d34-0410-b5e6-96231b3b80d8
