Chris Lattner 626aba43d0 eliminate dynamic_cast from the pass manager.

 2010-01-21 02:07:07 +00:00
Eric Christopher fa863258d0 Add strcpy_chk -> strcpy support for "don't know" object size 
answers.  This will update as object size checking gets better information.

Evan Cheng 5d30f7c91c Fix a minor issue in x86 load / store folding table. movups does an unaligned load so it doesn't require 16-byte alignment.

Jim Grosbach e029a6a5ed Make sure that landing pad entries in the EH call site table are in the proper 
order for SjLj style exception handling.

Sean Callanan 7a77eae2f3 Moved handling of inclusion from the AsmLexer to 
the AsmParser, breaking AsmLexer's dependence on
SourceMgr.

Chris Lattner 3c5bf71353 simplify this code. 
llvm-svn: 94048
 2010-01-20 23:30:28 +00:00
Sean Callanan 177934e021 Changed the AsmParser to handle error messages itself 
rather than passing them off to the AsmLexer to handle.
This means the AsmLexer no longer requires a SourceMgr
to do error handling.

llvm-svn: 94047
 2010-01-20 23:19:55 +00:00
Jim Grosbach d7cf27a1d1 SjLj EH introduces can introduce an additional edge to a landing pad and pad 
normalization needs to take this into account.

llvm-svn: 94046
 2010-01-20 23:03:55 +00:00
Sean Callanan 1a0eeb6e06 Promoted the reference to the SourceMgr from AsmLexer 
into AsmParser, in preparation for making AsmLexer
independent of the SourceMgr

llvm-svn: 94043
 2010-01-20 22:45:23 +00:00
Sean Callanan 70855e42e6 Modified MCAsmLexer to return error information upward 
rather than printing it locally, reducing its dependence
on SourceMgr.

Chris Lattner 32fb9564bc eliminate FnStubInfo, using MachineModuleInfoMachO instead. 
this makes function stub emission determinstic.

Dale Johannesen c5db599813 make findDebugLoc a class method 
llvm-svn: 94032
 2010-01-20 21:36:02 +00:00
Chris Lattner 2f7c279257 split function stub printing out to its own function, 
no functionality change.

llvm-svn: 94030
 2010-01-20 21:19:44 +00:00
Chris Lattner 1ff4794cbb eliminate the GVStubs and HiddenGVStubs maps, and use 
MachineModuleInfoMachO instead.  This eliminates two sources
of nondeterministic output in the ppc backend, but function
stubs are still bad.

Chris Lattner 1edfeb2c46 don't forget to initialize an instance variable!

David Greene 0985160c54 When XDEBUG is enabled, check for SelectionDAG cycles at some key 
points.  This will help us find future problems like the one
described in PR6019.

 2010-01-20 17:53:51 +00:00
Jakob Stoklund Olesen 8a19d3c96c Move per-function inline threshold calculation to a method. 
No functional change except the forgotten test for
InlineLimit.getNumOccurrences() == 0 in the CurrentThreshold2 calculation.

go completely away.

for tidiness.

 2010-01-20 07:19:19 +00:00
Chris Lattner 03cb2a3035 signficant cleanups to EmitGlobalConstant (including streamerization 
of int initializers), change some methods to be static functions,
use raw_ostream::write_hex instead of a smallstring dance with 
APValue::toStringUnsigned(S, 16).

Chris Lattner 45eeffcc2a make mcasmstreamer handle expanding 8 byte integer constants to 
4-byte constants if .quad isn't supported.  Switch a bunch of
methods used by the dwarf writer to use OutStreamer.EmitIntValue.

llvm-svn: 93987

Chris Lattner 38caaf14c1 give createAsmStreamer an 'isLittleEndian' argument. 
llvm-svn: 93986
 2010-01-20 06:39:07 +00:00
Chris Lattner 2b4364fe03 revert 93934, removing the MCAsmInfo endianness bit. I can't 
stomache MCAsmInfo having this, and I found a better solution to
this layering issue.

 2010-01-20 06:22:33 +00:00
Chandler Carruth d6514b1e13 Fix the conditions to unambiguously show the logic they represent. This is the 
logic enforced in the test case as well, so hopefully it is correct. Please
review Victor.

Devang Patel 7771b7c621 If a instruction belongs to another function (and not current function) as per debug info attached with the instruction then ignore the dangling lexical scope of this instruction. Such scopes are unreachable.

Dan Gohman 954f49014d Fold (add x, shl(0 - y, n)) -> sub(x, shl(y, n)), to simplify some code
