Owen Anderson 235c276442 Attempt to get Thumb2 branch fixups working properly.

 2010-12-10 23:02:28 +00:00
Bob Wilson 0348af667a Fix clang crashes on Neon vld[234]_dup intrinsics with 64-bit element types. 
The 64-bit element vectors need to be handled as a special case.

Jakob Stoklund Olesen adecb5e82c Force the greedy register allocator to always use the inline spiller. 
Soon, RegAllocGreedy will start splitting live ranges, and then deferred
spilling won't work anyway.

Jakob Stoklund Olesen 276445f3b8 Rip out live range splitting support from the inline spiller. 
The spiller should only spill. The register allocator will drive live range
splitting, it has the needed information about register pressure and
interferences.

Bill Wendling 006ab13b59 The MCFixupKindInfo table needs to be in the order that the enums were 
declared. Add a note specifying this and spruce up the list a bit.

Jim Grosbach e991a6ee5a More trivial cleanup. No need to define the EncoderMethod property type. Can 
just assign to it.

Michael J. Spencer f5799be4a8 Add CMake build and fix major Linux blockers. 
llvm-svn: 121510
 2010-12-10 19:47:54 +00:00
Bob Wilson a880fa0b28 Do not assert on shifts of Neon polynomial types. 
Most Neon shift intrinsics do not have variants for polynomial types, but
vsri_n and vsli_n do support them, and we need to properly range-check the
shift immediates for them.

llvm-svn: 121509
 2010-12-10 19:45:06 +00:00
Dan Gohman fb0a3754f5 Update this code to handle PartialAlias as MayAlias. 
llvm-svn: 121508
 2010-12-10 19:40:47 +00:00
Dan Gohman 4bd64fa805 Introduce a new PartialAlias response for AliasAnalysis. For most 
AliasAnalysis consumers, PartialAlias will be treated as MayAlias.

For AliasAnalysis chaining, MayAlias says "procede to the next analysis".
PartialAlias will be used to indicate that the query should terminate,
even though it didn't reach MustAlias or NoAlias.

 2010-12-10 19:38:58 +00:00
Bob Wilson d29b38c893 Fix some invalid alignments for Neon vld-dup and vld/st-lane instructions. 
Alignments smaller than the total size of the memory being loaded or stored,
unless the alignment is 8 bytes, are not allowed.  Add tests for this, too.

 2010-12-10 19:02:23 +00:00
Johnny Chen f3e22ac3c7 Add a '+a' command line option to the test driver to run only the Python API tests. 
Add an attribute __python_api_test__ (set to True) to the @python_api_test decorated
test method to distinguish them from the lldb command line tests.

Jim Grosbach bdb7ed16c1 Teach isCSRestore() that ARM/Thumb2 functions will use post-modify LDR 
instructions to restore a single register rather than an LDM instruction.

llvm-svn: 121498
 2010-12-10 18:41:15 +00:00
Jakob Stoklund Olesen 0c67e01e5f Add an AllocationOrder class that can iterate over the allocatable physical 
registers for a given virtual register.

Reserved registers are filtered from the allocation order, and any valid hint is
returned as the first suggestion.

For target dependent hints, a number of arcane target hooks are invoked.

Jim Grosbach e119da1146 Thumb unconditional branch binary encoding. rdar://8754994

 2010-12-10 18:21:33 +00:00
Douglas Gregor 8d34e5eb49 Replace two QualType::getTypePtrOrNull() calls with 
QualType::getTypePtr(). It turns out that
cast_or_null/dyn_cast_or_null don't actually use simplify_type, so
they're guaranteed to operator on non-NULL QualType or CanQualType
objects.

Good for a 0.6% win on 403.gcc's combine.c with -emit-llvm.
