Johnny Chen 25df2a75bd Better error-handling for DisassembleThumb2DPSoReg() where the 3-reg operand 
instructions should have Rd (Inst{11-8}) != 0b1111.

Johnny Chen cbe3e1a3df ARM disassembler did not react to recent changes to the NEON instruction table. 
VLD1q*_UPD and VST1q*_UPD have the ${dst:dregpair} operand now.

FU per CPU arch to 32 per intinerary allowing precise modelling of quite
complex pipelines in the future.

Nick Lewycky 554a39889b This is horrible. Split the difference, and declare 'environ' on all non-Darwin 
platforms to unbreak the darwin and linux builds. The BSD folks should feel
free to change the #if, if this breaks them.

Chris Lattner a50738abba make Program::Execute use posix_spawn on systems that support it, 
as it is more efficient than fork/exec.

Thanks to Eric for adding the autoconf check.  It would be nice if
a cmake guru could add a cmake check for posix_spawn as well.

Bill Wendling 268195e1d4 Don't rely upon the MCSymbol "isDefined" method to indicate if a label has been 
emitted or not. The JIT doesn't set that. Look it up in the label location table
instead.

Chris Lattner 67e70971cc fix PR6858: a dangling pointer use bug which was caused 
by switching CachedFunctionInfo from a std::map to a 
ValueMap (which is implemented in terms of a DenseMap).

DenseMap has different iterator invalidation semantics
than std::map.

This should hopefully fix the dragonegg builder.

llvm-svn: 101636
 2010-04-17 15:31:16 +00:00
Dan Gohman 21cea8ac2e Use const qualifiers with TargetLowering. This eliminates several 
const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static member function, because
PIC16 uses it in an unconventional way. There is more room for API
cleanup here.

And PIC16's AsmPrinter no longer uses TargetLowering.

Chandler Carruth ca0a53ac52 Name these stub files consistently with the SPU and PPC targets' conventions. 
Also rename the classes appropriately. The CMake build already used these
names.

Chris Lattner 7f5088e6de a bunch of ssse3 instructions are misencoded to think they have an 
i8 field when they really do not.  This fixes rdar://7840289

 2010-04-17 07:38:24 +00:00
Chris Lattner 7c4f14bf90 reenable r101565, removing a problematic assertion. 
CGSCC can delete nodes in regions of the callgraph that
have already been visited.  If new CG nodes are allocated
to the same pointer, we shouldn't abort, just handle it
correctly by assigning a new number.  This should restore
stability by removing invalidated pointers that *will* be
reused from the densemap in the iterator.

Bob Wilson 59b70eacad Revise my previous change to ExpandBIT_CONVERT. I hadn't realized that this 
may be called when either the source or destination type is i64, and my
change also hadn't fixed the most obvious problem -- assuming that i64 will
only be bitconverted to f64, ignoring the various vector types.

 2010-04-17 05:30:19 +00:00
Bob Wilson ca51425d94 Re-commit my previous SSAUpdater changes. The previous version naively tried 
to determine where to place PHIs by iteratively comparing reaching definitions
at each block.  That was just plain wrong.  This version now computes the
dominator tree within the subset of the CFG where PHIs may need to be placed,
and then places the PHIs in the iterated dominance frontier of each definition.
The rest of the patch is mostly the same, with a few more performance
improvements added in.
