7291272ab2 Add mayLoad attribute to AVX convert instructions, since non of them
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.

08ecb711ac Fix PR10884.
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.

ffee5728af Move the AC_PROG_CC checks earlier in the configure file. The lateness
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.

ebac0c1747 Spill mode: Hoist back-copies locally.
The leaveIntvAfter() function normally inserts a back-copy after the
requested instruction, making the back-copy kill the live range.

In spill mode, try to insert the back-copy before the last use instead.
That means the last use becomes the kill instead of the back-copy.  This
lowers the register pressure because the last use can now redefine the
same register it was reading.

This will also improve compile time: The back-copy isn't a kill, so
hoisting it in hoistCopiesForSize() won't force a recomputation of the
source live range.  Similarly, if the back-copy isn't hoisted by the
splitter, the spiller will not attempt hoisting it locally.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139883 91177308-0d34-0410-b5e6-96231b3b80d8

69cf1cac3f Disable local spill hoisting for non-killing copies.
If the source register is live after the copy being spilled, there is no
point to hoisting it.  Hoisting inside a basic block only serves to
resolve interferences by shortening the live range of the source.
