have a fixme about it.

generates the dwarf Compile Unit DIE and a dwarf subprogram DIE for each
non-temporary label.

The next part will be to get the clang driver to enable this when assembling
a .s file.  rdar://9275556

Move isUnpredicatedTerminator() default implementation to TargetInstrInfoImpl to break Target's dependency on CodeGen.

Patch by Brendon Cahoon!

This extends the existing LoopUnroll and LoopUnrollPass. Brendon
measured no regressions in the llvm test suite with -unroll-runtime
enabled. This implementation works by using the existing loop
unrolling code to unroll the loop by a power-of-two (default 8). It
generates an if-then-else sequence of code prior to the loop to
execute the extra iterations before entering the unrolled loop.

symbol difference. This matches gas behavior and fixes PR11513.

We still don't handle _GLOBAL_OFFSET_TABLE_ in data sections.

Enhance both TargetLibraryInfo and SelectionDAGBuilder so that the latter can use the former to prevent the formation of libm SDNode's when  -fno-builtin is passed.

Filter "sink to" candidate blocks sooner. This avoids unnecessary computation to determine whether the block dominates all uses or not.

MipsTargetLowering::LowerGlobalTLSAddress. This is necessary to have
call16(__tls_get_addr) emitted instead of got_disp(__tls_get_addr) when the
target is Mips64.

Don't explicitly marked libm rounding ops as legal on SSE4.1/AVX.  There don't seem to be patterns for these, so I don't know why they were marked legal in the first place.
Fixes failures caused by r146171.

- Modify lowering of global TLS address nodes.
- Modify isel of ThreadPointer.
- Wrap target global TLS address nodes that are operands of loads with WrapperPIC. 
- Remove Mips-specific DAG nodes TlsGd, TprelHi and TprelLo, which can be
  substituted with other existing nodes.

llvm-svn: 146175

Teach SelectionDAG to match more calls to libm functions onto existing SDNodes.  Mark these nodes as illegal by default, unless the target declares otherwise.
