Bruno Cardoso Lopes 6963062a99 Use fp unpack instructions to unpack int types. Until we have AVX2, this 
is the best we can do for these patterns. This fix PR10554.

Rafael Espindola 07f6091527 Add a C interface to PassManagerBuilder. It is missing the addExtension 
functionality since in the C api a pass is created and added to a pass
manager in a single call.

Jim Grosbach a317160348 Don't truncate MachO addresses. 
Assigned symbol addresses get truncated to 32-bits, even on 64-bit platforms.
That's obviously bogus.
For example,

 .globl _foo
 .equ _foo, 0x987654321ULL

Eli Friedman 84cd7927b9 First draft of the practical guide to atomics. 
This is mostly descriptive of the intended state once atomic load and store have landed.

Owen Anderson e0152a73c2 Replace the existing ARM disassembler with a new one based on the FixedLenDecoderEmitter. 
This new disassembler can correctly decode all the testcases that the old one did, though
some "expected failure" testcases are XFAIL'd for now because it is not (yet) as strict in
operand checking as the old one was.

Jim Ingham 04f5672c5b When unloading a library, pass the old complete version of the library to UnloadImageLoadAddress, since that 
one is completely filled in.  The one we make up from the event doesn't have section info since the
library has already been unloaded by the time we get to it.

Sean Callanan 85a96b12de Fixed the Objective-C "self" test case, which 
was behaving erratically because it didn't
have a return statement in -[A init].

Also made minor cosmetic changes to that test
case.

Johnny Chen 53e2edbc5c Simplify lang/objc/self/Makefile, plus it's wrong. :-) 
For Makefile.rules, the modification of CFLAGS (addition of -arch $(ARCH) for Darwin) needs to come before
the consuming of CFLAGS, not after.

Jakob Stoklund Olesen 53910d6aae Inflate register classes after coalescing. 
Coalescing can remove copy-like instructions with sub-register operands
that constrained the register class.  Examples are:

  x86: GR32_ABCD:sub_8bit_hi -> GR32
  arm: DPR_VFP2:ssub0 -> DPR

Recompute the register class of any virtual registers that are used by
less instructions after coalescing.

This affects code generation for the Cortex-A8 where we use NEON
instructions for f32 operations, c.f. fp_convert.ll:

  vadd.f32  d16, d1, d0
  vcvt.s32.f32  d0, d16

The register allocator is now free to use d16 for the temporary, and
that comes first in the allocation order because it doesn't interfere
with any s-registers.

Sean Callanan 677f2a263a Fixed a problem where the HasAVX() code in 
debugserver did not back up %ebx/%rbx, even
though it was being clobbered by the CPUID

Caitlin Sadowski 4b1e8399c2 Thread Safety: Added basic argument parsing for all new attributes. 
This patch special cases the parser for thread safety attributes so that all
attribute arguments are put in the argument list (instead of a special
parameter) since arguments may not otherwise resolve correctly without two-token
lookahead.

This patch also adds checks to make sure that attribute arguments are
lockable objects.

Bruno Cardoso Lopes bed48dc8ff Reapply a more appropriate solution than in r137114. AVX supports 
v4f64 = sitofp v4i32. This fix PR10559.

Douglas Gregor 636e200675 Move the creation of the record type for the state of Objective-C fast 
enumerations from the ASTContext into CodeGen, so that we don't need
to serialize it to AST files. This appears to be the last of the
low-hanging fruit for SpecialTypes.

Jakob Stoklund Olesen da96006975 Move CalculateRegClass to MRI::recomputeRegClass. 
This function doesn't have anything to do with spill weights, and MRI
already has functions for manipulating the register class of a virtual
register.

Douglas Gregor 7874310ba1 Don't serialize the block descriptor or block extended descriptor 
types to AST files; they're only used by debug info generation anyway,
and shouldn't ever exist in the AST anyway.

llvm-svn: 137122
 2011-08-09 16:24:26 +00:00
Douglas Gregor abf4e0dfcd Move the construction of the RecordDecl representing the runtime 
layout of a constant NSString from the ASTContext over to CodeGen,
since this is solely CodeGen's responsibility. Eliminates one of the
unnecessary "special" types that we serialize.

Douglas Gregor eda8e12e86 Migrate the serialization of ASTContext's AutoDeduceTy and 
AutoRRefDeductTy from the "special types" block to predefined
types. The latter behaves better when loading multiple AST files.
