Fix typo in PerformAddCombine that caused any vector type to be checked for horizontal add/sub if AVX2 is enabled. This caused an assert to fail for non 128/256-bit vectors when done before type legalizing. Fixes PR11749.

The code type was always identical to a string anyway. Now it is simply
a synonym. The code literal syntax [{...}] is still valid.

This avoids a gazillion StringMap and dynamic_cast calls, making
TableGen run 3x faster.

overly conservative. It was concerned about cases where it would prohibit
folding simple [r, c] addressing modes. e.g.
  ldr r0, [r2]
  ldr r1, [r2, #4]
=>
  ldr r0, [r2], #4
  ldr r1, [r2]
Change the logic to look for such cases which allows it to form indexed memory
ops more aggressively.

the optimizer doesn't eliminate objc_retainBlock calls which are needed
for their side effect of copying blocks onto the heap.

The registers are placed into the saved registers list in the reverse order,
which is why the original loop was written to loop backwards.

llvm-svn: 148064

Added FPOW, FEXP, FLOG to PromoteNode so that custom actions can be set to Promote for those operations.

Sorry, no test case yet

Added a test.

killed registers are needed below the insertion point, then unset the kill
marker.

Sorry I'm not able to find a reduced test case.

This patch uses tcb_spare field in the tcb structure to store info.

Uses the pvArbitrary slot of the TIB, which is reserved for applications. We
only support frames with a static size.

Restore the (obviously wrong) behavior from before r147938 without relying on
undefined behavior. Add a fat FIXME note.

This should fix nightly tester failures.

Fix a bug in the AVX 256-bit shuffle code in cases where the splat element is on the boundary of two 128-bit vectors.
The attached testcase was stuck in an endless loop.

X86: Generalize the x << (y & const) optimization to also catch masks with more set bits set than 31 or 63.

In att style asm syntax memory operand size is derived from suffix attached with mnemonic.  In intel style asm syntax it is part of memory operand hence predicate method check is required to select appropriate instruction.

need to make a deep copy of each of the std::maps. Use a std::map of the
std::map instead. This improves the compile time of sqlite3 by ~2%.

This is a work in progress.

same pattern. We already had this pattern is a few places, but others
tried to make a rough approximation of an actual DAG structure. As not
everywhere went to this trouble, nothing could rely on this being done.
In fact, I've checked all references to these node Ids, and the ones
that are using the topo-sort properties are actually satisfied with
a strict-weak-ordering. The requirement appears to be that Use >= Def.

I've added a big blurb of comments to this bit of the transform to
clarify why the order is so important for the next reader of the code.

I'm starting with this change as it is very small, and trivially
reverted if something breaks or the >= above really does need to be >.
If that proves the case, we can hide the problem by reverting this
patch, but the problem exists elsewhere as well, and so a more
comprehensive solution will be needed.

Re-fix the issue Bill fixed in r147899 in a slightly different way, which doesn't abuse the semantics of linker_private.  We don't really want to merge any string constant with a weak_odr global.
