Chris Lattner c6c153be45 fix a SCCP miscompilation that could happen when a 
forced constant is changed to a constant, we would end
up adding the instruction to the wrong worklist, 
preventing it from being properly revisited.  This fixes
rdar://7832370

llvm-svn: 100837
 2010-04-09 01:14:31 +00:00
Sean Callanan 48b1804e79 Bugfixes for edis. Code to initialize instruction 
state was being executed too lazily, and the LLVM
assembly syntax for the disassembler was not being
written into the proper disassembler state variable.

llvm-svn: 100812
 2010-04-08 21:26:26 +00:00
Johnny Chen 75f82345c4 Now that Evan Cheng has fixed the coalescer bug (r100804), the workaround code 
to avoid memcpy() call is no longer necessary.

llvm-svn: 100811
 2010-04-08 21:23:54 +00:00
Chris Lattner 433d40695b remove the TargetLoweringObjectFileMachO::getMachoSection 
api and update clients to use MCContext instead.

llvm-svn: 100808
 2010-04-08 20:40:11 +00:00
Chris Lattner 2073112fc0 move macho section uniquing from MCParser and TLOF to MCContext where 
the compiler and asmparser now unique to the same sections.  This fixes
rdar://7835021.

Jeffrey Yasskin 96f8a4a82f Touch configure so it regenerates Disassemblers.def to include ARM so 
people stop seeing a broken build in EDDisassembler.cpp

llvm-svn: 100782
 2010-04-08 17:19:20 +00:00
Devang Patel 3ebd8931fb One instruction may start (or end) multiple lexical scopes. 
There is no need to remember labels identifying regions marked by such instructions in each scope.

llvm-svn: 100767
 2010-04-08 15:25:57 +00:00
Benjamin Kramer a1eafb9afd Provide operator delete for BumpPtrAllocator and RecyclingAllocator. They will

 2010-04-08 09:42:29 +00:00
Evan Cheng ebe47c872f Avoid using f64 to lower memcpy from constant string. It's cheaper to use i32 store of immediates. 
llvm-svn: 100751
 2010-04-08 07:37:57 +00:00
Dan Gohman 883105485b Revert this change from a while ago; ScalarEvolution shouldn't analyze 
undef as 0, since it can't force other analyses to intepret the undef
in the same way.
