on lldb's Driver::MainLoop function which is ~1190 lines of x86 assembly code.  This file is not
exercised during the normal test suite run, i.e., no +b option specified.  So it should be ok.

The following is the benchmark result on my MBP running OSX Lion:

llvm-svn: 137086

llvm-svn: 137085

llvm-svn: 137084

A public interface is no longer needed since RegisterCoalescer is not an
analysis any more.

Use the the path that generates a loop. This fixes
bogus error that clang puts out. // rdar://9894548

command that allows us to see all modules that exist and
their corresponding global shared pointer count. This will
help us track down memory issues when modules aren't being
removed and cleaned up from the module list.

Add EvaluateWithError static method.  Fix a bug in handling constant expressions - we weren't setting the result even though the expression evaluation succeeded...

Fix the instruction representation to correctly only allow post-indexed form.
Add tests.

They improve the verbose assembly.

Fix another -Wuninitialized assertion failure (this one involving bit casts) resulting from the recent -Wuninitialized changes.

Allow labels for load/store instructions when parsing. There's encoding
issues, still, so this doesn't work all the way through, yet.

llvm-svn: 137064

These the methods are target-independent since they simply scan the
memory operands.  They can live in TargetInstrInfoImpl.

llvm-svn: 137063

Fix encodings for Thumb ASR and LSR immediate operands.  They encode the range 1-32, with 32 encoded as 0.

llvm-svn: 137062

Fix up the patterns for SXTB, SXTH, UXTB, and UXTH so that they are correctly active without HasT2ExtractPack.  PR10611.

llvm-svn: 137060

Add MCInstrAnalysis class. This allows the targets to specify own versions of MCInstrDescs functions.

- Add overrides for ARM.
- Teach llvm-objdump to use this instead of plain MCInstrDesc.

llvm-svn: 137059

- Indent simple loops
- Print unreachable blocks as .byte directives

llvm-svn: 137058

This way we can avoid printing unreachable code (data).

This patch fixes the previous patch where warnings were coming out in
non-deterministic order.  This is 2nd part of // rdar://6191214.

implementations of +load do not replace the class definition in a meaningful
sense, they are run when the category loads, the +load method for class is run
when the class is loaded.

Thanks to David Blaikie for pointing this out.

X86FloatingPoint keeps track of pending ST registers for an upcoming
inline asm instruction with fixed stack register constraints.  It does
this by remembering which FP register holds the value that should appear
at a fixed stack position for the inline asm.

When that FP register is killed before the inline asm, make sure to
duplicate it to a scratch register, so the ST register still has a live
FP reference.

This could happen when the same FP register was copied to two ST
registers, or when a spill instruction is inserted between the ST copy
and the inline asm.

This fixes PR10602.
