has broken a build.

llvm-svn: 118475

 2010-11-09 02:11:43 +00:00
Ted Kremenek 16e6026f01 Fix InitListExpr::getSourceRange() to work in the case of no locations for '(' and ')'. This can happen 
in the case of transparent unions.

Dan Gohman 5db8921422 Fix DAGCombiner to avoid folding a sext-in-reg or similar through a shl 
in order to fold it into a load.

llvm-svn: 118471

Dan Gohman 4677bafd85 Delete an extraneous svn:executable property.

 2010-11-09 01:51:06 +00:00
Jim Grosbach 9098714f8b Add support for a few simple fixups to the ARM Darwin asm backend. This allows 
constant pool references and global variable refernces to resolve properly
for object file generation. For example,

int x;
void foo(unsigned a, unsigned *p) {
  p[a] = x;
}

can now be successfully compiled directly to an (ARM mode) object file.

Argyrios Kyrtzidis 8909686b22 Fix miscompilation regarding VLAs; subscription of VLA pointers was incorrect. 
Fixes rdar://8644873 & http://llvm.org/PR8567.

llvm-svn: 118468
 2010-11-09 01:30:48 +00:00
Jason Molenda 45b4924550 Fix thinko in UnwindTable.cpp where it wouldn't provde a 
FuncUnwinders object if the eh_frame section was missing
from an objfile.  Worked fine on x86_64 but on i386 where
eh_frame is unusual, that resulted in the arch default 
UnwindPlan being used all the time instead of picking up
an assembly profile based unwindplan.

John McCall 478382521e When re-using a vtable slot for the nearest overridden method, just because 
there's no return adjustment from the overridden to the overrider doesn't
mean there isn't a return adjustment from the overrider to the final
overrider.  This matters if we're emitting a virtual this-adjustment thunk
because the overrider virtually inherits from the class providing the
nearest overridden method.  Do the appropriate return adjustment in this case.

Fixes PR7611.

Owen Anderson 9b14a25126 Fix PR8441, a race condition in the static attributes list. While the reference counting was itself threadsafe, 
the implicit removal of each object from the global list was not.  Make this operation atomic.

Johnny Chen 31f29e98bf Add keyboard shortcuts: 
'run'          => Control-C r (gud-run)            "Run the program."
'process kill' => Control-C s (gud-stop-subjoball) "Stop the program."

Nick Lewycky 14d88eb41f Fix warning about unused variable 'Fn' in no-asserts builds. Also reflow this 
block so that it looks more like the rest of the file. No functional change.

Craig Silverstein 174241e9a0 1) Fix a typo in PPCallbacks: It's elif, not elfif. :-) This is 
contentful, since the typo was in the method-name...

2) Clarify some comments in RecursiveASTVisitor.

Ted Kremenek 15c1e368bb Add CursorVisitor::VisitBinaryOperator() to explicitly handle the case where we can blow out the stack due 
to deeply nested BinaryOperators.  This is done by turning the explicit recursion into being data recursive.

Douglas Gregor dc520b0f08 If an instance method messages is sending to an expression of type Class, 
and we statically can compute a bound on the actual type (e.g.,
because it's a send to the the magic "class" instance method), code
complete as if we were performing a class message send to that class.

Johnny Chen c06f422d73 Let's also emit the informational message for where to find the session logs for 
failed/errored tests at the start of the test run, in case the test run crashes
for any reason.  That way, it is easy to locate the session logs for accumulated
failures/errors.

Douglas Gregor bd6b17f4ef Improve our handling of C++ [class.copy]p3, which specifies that a 
constructor template will not be used to copy a class object to a
value of its own type. We were eliminating all constructor templates
whose specializations look like a copy constructor, which eliminated
important candidates. Fixes PR8182.
