2011-09-18When promoting integer vectors we often create ext-loads. This patch adds aNadav Rotem
dag-combine optimization to implement the ext-load efficiently (using shuffles). For example the type <4 x i8> is stored in memory as i32, but it needs to find its way into a <4 x i32> register. Previously we scalarized the memory access, now we use shuffles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139995 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-17Synthesize x86 max/min instructions also for vectors (i.e. produceDuncan Sands
maxps and maxpd). This broke the sse41-blend.ll testcase by causing maxpd to be produced rather than a cmp+blend pair, which is the reason I tweaked it. Gives a small speedup on doduc with dragonegg when the GCC vectorizer is used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139986 91177308-0d34-0410-b5e6-96231b3b80d8

are declared with load patterns. This fix the crash in PR10941. No testcases, since a fold is triggered and then converted back to the register form afterwards. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139953 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-16Fix PR10884.Bruno Cardoso Lopes
This PR basically reports a problem where a crash in generated code happened due to %rbp being clobbered: pushq %rbp movq %rsp, %rbp .... vmovmskps %ymm12, %ebp .... movq %rbp, %rsp popq %rbp ret Since Eric's r123367 commit, the default stack alignment for x86 32-bit has changed to be 16-bytes. Since then, the MaxStackAlignmentHeuristicPass hasn't been really used, but with AVX it becomes useful again, since per ABI compliance we don't always align the stack to 256-bit, but only when there are 256-bit incoming arguments. ReserveFP was only used by this pass, but there's no RA target hook that uses getReserveFP() to check for the presence of FP (since nothing was triggering the pass to run, the uses of getReserveFP() were removed through time without being noticed). Change this pass to use setForceFramePointer, which is properly called by MachineFunction hasFP method. The testcase is very big and dependent on RA, not sure if it's worth adding to test/CodeGen/X86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139939 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-16Move the AC_PROG_CC checks earlier in the configure file. The latenessEric Christopher
of the original check meant that configure was caching the default CC check and using that instead of the result of AC_PROG_CC in both configure checks and during compilation. This wasn't affecting C++ so it was hard to notice. Regenerate configure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139937 91177308-0d34-0410-b5e6-96231b3b80d8
