Jim Grosbach 0c03a3a146 Revert r125595, which is an X86-only undocumented assembly syntax extension 
enabled for all targets. Non-X86 targets should not have this behavior
enabled by default.

Joerg, if you would like to resubmit with the behavior conditionalized to be
X86-ELF only, that's fine.

Argyrios Kyrtzidis f1b5d1f01b [analyzer] Refactor EndOfFunctionNodeBuilder. 
-Introduce EndOfFunctionNodeBuilder::withCheckerTag to allow it be "specialized" with a
 checker tag and not require the checkers to pass a tag.
-For EndOfFunctionNodeBuilder::generateNode, reverse the order of tag/P parameters since
 there are actual calls that assume the second parameter is ExplodedNode.

Chandler Carruth e71b378dc7 Fix the behavior of -Wignored-qualifiers on return type qualifiers in 
several ways. We now warn for more of the return types, and correctly
locate the ignored ones. Also adds fix-it hints to remove the ignored
qualifiers. Fixes much of PR9058, although not all of it.

Patch by Hans Wennborg, a couple of minor style tweaks from me.

Richard Osborne 4995b05f56 Add llvm.xcore.waitevent intrinsic. The effect of this intrinsic is to enable 
events on the thread and wait until a resource is ready to event. The vector
of the resource that is ready is returned.

Sean Callanan 34770edf43 Fixed a bug in the enhanced disassembler that caused

 2011-02-23 02:26:43 +00:00
Evan Cheng d6b641e5bc More fcopysign correctness and performance fix. 
The previous codegen for the slow path (when values are in VFP / NEON
registers) was incorrect if the source is NaN.

The new codegen uses NEON vbsl instruction to copy the sign bit. e.g.
        vmov.i32        d1, #0x80000000
        vbsl    d1, d2, d0
If NEON is not available, it uses integer instructions to copy the sign bit.

 2011-02-23 01:52:07 +00:00
Ted Kremenek 3427fac7c8 Enhance Sema::DiagRuntimeBehavior() to delay some diagnostics to see if the related code is reachable. This suppresses some 
diagnostics that occur in unreachable code (e.g., -Warray-bound).

We only pay the cost of doing the reachability analysis when we issue one of these diagnostics.

Ted Kremenek 55ae319a28 Update Sema::DiagRuntimeBehavior() to take an optional Stmt* to indicate the code the diagnostic is associated with. 
This Stmt* is unused, but we will use it shortly for pruning diagnostics associated
with unreachable code.
