Assigned symbol addresses get truncated to 32-bits, even on 64-bit platforms.
That's obviously bogus.
For example,

 .globl _foo
 .equ _foo, 0x987654321ULL

Not sure about BLXi, but this is what the old disassembler did.

The new ARM disassembler disassembles "bx lr" as a special BX_ret instruction so target specific analysis isn't needed anymore.

This is mostly descriptive of the intended state once atomic load and store have landed.  

llvm-svn: 137145

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.

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.

have a return statement in -[A init].

Also made minor cosmetic changes to that test
case.

For Makefile.rules, the modification of CFLAGS (addition of -arch $(ARCH) for Darwin) needs to come before
the consuming of CFLAGS, not after.

Fix a crash while running the test suite.  Need to check the (LogSP)log shared pointer before using it.

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.

debugserver did not back up %ebx/%rbx, even
though it was being clobbered by the CPUID
instruction.

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.

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.

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.

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

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.

AutoRRefDeductTy from the "special types" block to predefined
types. The latter behaves better when loading multiple AST files.

cpu registers it uses and it crashes the release version of 
debugserver. We just get lucky in Debug builds. Until this 
is fixed I am disabling AVX detection to avoid the crashes.
