Ted Kremenek da4abf11bf Allocate 'ObjCMethodList' objects (owned by Sema) using Sema's BumpPtrAllocator. Previously they were not getting freed. Fixes <rdar://problem/7635663>.

Jakob Stoklund Olesen 75521cab3e Reuse operand location when updating PHI instructions. 
Calling RemoveOperand is very expensive on huge PHI instructions. This makes
early tail duplication run twice as fast on the Firefox JavaScript
interpreter.

Jakob Stoklund Olesen 896428d630 Remove duplicate successors from indirectbr instructions before building the machine CFG. 
This makes early tail duplication run 60 times faster when compiling the Firefox
JavaScript interpreter, see PR6186.

Kevin Enderby cfd0e5a15e Update the X86 assembler matcher test case now that a few more things match 
with some of the recent changes that have gone into llvm-mc.

multiple global variables at a time.

Mon P Wang 5b77f0dac1 The previous fix of widening divides that trap was too fragile as it depends on custom 
lowering and requires that certain types exist in ValueTypes.h.  Modified widening to
check if an op can trap and if so, the widening algorithm will apply only the op on
the defined elements.  It is safer to do this in widening because the optimizer can't
guarantee removing unused ops in some cases.

Charles Davis 42b3842429 Fix a potential null-pointer use, and fix the style of my new function. 
Thanks, Anton!

Charles Davis bbc0aa5166 Add support for the force_align_arg_pointer attribute. This is an x86-specific 
attribute, so it uses Anton's new target-specific attribute support. It's
supposed to ensure that the stack is 16-byte aligned, but since necessary
support is lacking from LLVM, this is a no-op for now.

Bob Wilson 0f52d0c074 Delete dead PHI machine instructions. These can be created due to type 
legalization even when the IR-level optimizer has removed dead phis, such
as when the high half of an i64 value is unused on a 32-bit target.
I had to adjust a few test cases that had dead phis.
This is a partial fix for Radar 7627077.

Bill Wendling 7742b6406b Use an index instead of pointers into the vector. If the vector resizes, then 
the pointer values could be invalid.

Dan Gohman c42c5243a1 Use an AssemblyAnnotatorWriter to clean up IVUsers' debug output. 
The "uses=" comments are just clutter in this context.

llvm-svn: 95799
 2010-02-10 20:42:37 +00:00
Dan Gohman e34890f921 Add a hook to AssemblyAnnotationWriter to allow custom info comments

Kevin Enderby cc152d6159 Replace this file containing 4 tests of x86 32-bit encodings with a file 
containing the subset of the full auto generated test case that currently
encodes correctly.  Again it is useful as we bring up the the new encoder
to make sure currently working stuff stays working.

Daniel Dunbar 3241d400c8 Switch to using -fsjlj-exceptions instead of hard-coding it. Notably, this fixes 
calls to the UnwindResumeOrRethrow function for C++/Obj-C exception handling,
for Darwin ARM.

llvm-svn: 95783
 2010-02-10 17:47:19 +00:00
Douglas Gregor 2fbe558cfe Teach AST merging that variables with incomplete array types can be 
merged with variables of constant array types. Also, make sure that we
call DiagnosticClient's BeginSourceFile/EndSourceFile, so that it has
a LangOptions to work with.

Daniel Dunbar f22553a1c7 MC/AsmMatcher: Add support for creating tied operands when constructing MCInsts. 
- Pretty messy, but we need to rework how we handle tied operands in MCInst
   anyway.
