2008-06-25Remember which MachineOperand we were processing, so we don't have to scan ↵Owen Anderson
the list to find it again later. This speeds up live intervals from 0.37s to 0.30s on instcombine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52745 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-25- Fix a x86 vector isel bug: illegal transformation of a vector_shuffle into aEvan Cheng
shift. - Add a readme entry for a missing vector_shuffle optimization that results in awful codegen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52740 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-25Add support for expanding PPC 128 bit floats.Duncan Sands
For this it is convenient to permit floats to be used with EXTRACT_ELEMENT, so I tweaked things to allow that. I also added libcalls for ppcf128 to i32 forms of FP_TO_XINT, since they exist in libgcc and this case can certainly occur (and does occur in the testsuite) - before the i64 libcall was being used. Also, the XINT_TO_FP result seemed to be wrong when the argument is an i128: the wrong fudge factor was added (the i32 and i64 cases were handled directly, but the i128 code fell through to some generic softening code which seemed to think it was i64 to f32!). So I fixed it by adding a fudge factor that I found in my breakfast cereal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52739 91177308-0d34-0410-b5e6-96231b3b80d8

Unfortunately, this slow the testcase down a little bit, but only marginally. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52700 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-24Append to the ActiveTimers std::vector before looking at the timer insteadDan Gohman
of after, so that any reallocation it does doesn't get counted for the pass being timed. This probably doesn't account for a timing discrepancy I was looking into, but I'm fixing it anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52693 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-24v2f32 is now a valid (MMX) type which breaks thisDale Johannesen
test (doesn't work for any MMX vector types, it's not me). Rewritten to use v2i16 which is generic and going to stay that way; I think that preserves the point of the test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52692 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-24Add v2f32 (MMX) type to X86. Support is primitive:Dale Johannesen
load,store,call,return,bitcast. This is enough to make call and return work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52691 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-24In ConstantArray::getAsString(), we know the size of the resultant string in ↵Owen Anderson
advance so we can pre-allocate it and just fill in the entries. This improves the time for the AsmPrinter on InstructionCombining.cpp from 0.4248s to 0.3370s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52690 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-24Allow the test suite to be checked out into projects/test-suite.Matthijs Kooijman
We will keep the old projects/llvm-test working for existing installs. The changes to configure are made manually, since I lack autoconf-2.6.
