Matt Arsenault e81944fd5e SeparateConstOffsetFromGEP: Pass address space to isLegalAddressingMode 
llvm-svn: 239262
 2015-06-07 20:17:44 +00:00
Matt Arsenault fb88aca348 Make NaryReassociate pass the address space to isLegalAddressingMode 
No test since the kinds of transforms this prevents seem to not really
be relevant for SI's different addressing modes.

Matt Arsenault e83379e8e4 Add isLegalAddressingMode address space argument to TTI 
Update to match the TLI version, and remove the TLI version's
default argument.

Peter Zotov 3c40cbb812 [cmake] [OCaml] Make ocamldoc targets depend on output files 
OCaml doc builds fail without .cmi files, and .cmi files are collected
in ocaml_outputs. Therefore, make doc targets depend on ocaml_outputs as
well.

Rui Ueyama cc608e4f35 COFF: Rename writeHeader -> writeHeaderTo. 
Chunk has writeTo function which takes uint8_t *Buf.
writeHeaderTo feels more consistent with that because this member

Rui Ueyama c6ea057d7f COFF: Move .idata constructor from Writer to Chunk. 
Previously, half of the constructor for .idata contents was in Chunks.cpp

Now IdataContents class manages everything for .idata section.

Sanjoy Das ad714b1af3 [LoopUnroll] Fix truncation bug in canUnrollCompletely. 
Summary:
canUnrollCompletely takes `unsigned` values for `UnrolledCost` and
`RolledDynamicCost` but is passed in `uint64_t`s that are silently
truncated.  Because of this, when `UnrolledSize` is a large integer
that has a small remainder with UINT32_MAX, LLVM tries to completely
unroll loops with high trip counts.

David Majnemer 1c297e66fb [CVP] Don't assume Constants of type i1 can be known to be true or false 
CVP wants to analyze the condition operand of a select along an edge.
It succeeds in getting back a Constant but not a ConstantInt.  Instead,
it gets a ConstantExpr.  It then assumes that the Constant must be equal
to false because it isn't equal to true.

Instead, perform an additional comparison.

This fixes PR23752.

Rui Ueyama 743afa0736 COFF: Merge Chunk::applyRelocations with Chunk::writeTo. 
In this design, Chunk is the only thing that knows how to write
its contents to output file as well as how to apply relocations
there. The writer shouldn't know about the details.

David Majnemer 468f670021 [InstCombine] Don't miscompile select to poison 
If we have (select a, b, c), it is sometimes valid to simplify this to a
single select operand.  However, doing so is only valid if the
computation doesn't inject poison into the computation.

It might be helpful to consider the following example:
  (select (icmp ne %i, INT_MAX), (add nsw %i, 1), INT_MIN)

The select is equivalent to (add %i, 1) but not (add nsw %i, 1).

Self hosting on x86_64 revealed that this occurs very, very rarely so
bailing out is hopefully pretty reasonable.
