Johnny Chen 2b7aba10c2 In the same spirit of r101524, which removed the assert() from printAddrMode2OffsetOperand(), 
this patch removes the assert() from printAddrMode3OffsetOperand() and adds a test case.

Johnny Chen 807e1748fc Multiclass LdStCop was using pre-UAL syntax LDC<c>L for the L fragment. Changed 
to the UAL syntax of LDCL<c>, instead.

Add a test case for this change which also tests the removal of assert() from
printAddrMode2OffsetOperand().

Douglas Gregor 5c8ffab9fb Switch the checking of implicit casts for static_cast, C-style, and 
functional casts over to InitializationSequence, eliminating a caller
of Sema::TryImplicitConversion. We also get access and ambiguity
checking "for free".

More cleanups to come in this routine.

see http://google1.osuosl.org:8011/builders/dragonegg-x86_64-linux/builds/693
Original commit text:
Use a ValueMap not a std::map for the reason indicated
in the comment.  This was causing nondeterministic changes
in inlining decisions.

Dan Gohman 6e8427e066 Remove this hard-coded buffer size. In some basic experiments preprocessing 
large files, this doesn't seem significantly better than just letting
raw_ostream pick a buffer size.

This code predates raw-ostream's automatic buffer sizing; in fact, it
was introduced as part of the code which would eventually become
raw_ostream.

Dan Gohman f13f69f296 Disable inlining of recursive calls. It can complicate tailcallelim and 
dependent analyses, and increase code size, so doing it profitably would
require more complex heuristics.

Gabor Greif f375520f7b reapply r101434 
with a fix for self-hosting

rotate CallInst operands, i.e. move callee to the back
of the operand array

the motivation for this patch are laid out in my mail to llvm-commits:
more efficient access to operands and callee, faster callgraph-construction,
smaller compiler binary

Bill Wendling ae4541d758 Add JIT exception handling test. 
llvm-svn: 101455
 2010-04-16 09:04:28 +00:00
Bill Wendling 929f3c0927 The JIT calls TidyLandingPads to tidy up the landing pads. However, because the 
JIT doesn't use the MC back-end asm printer to emit labels that it uses, the
section for the MCSymbol is never set. And thus the MCSymbol for the EH label
isn't marked as "defined". Because of that, TidyLandingPads removes the needed
landing pads from the JIT output. This breaks EH for every JIT program.

This is a work-around for this limitation. We pass in the label locations
map. If the label has a non-zero value, then it was "emitted" by the JIT and
TidyLandingPads shouldn't remove that label.

A nicer solution would be to mark the MCSymbol as "used" by the JIT and not rely
upon the section being set to determine if it's defined or not.

Evan Cheng af56facacd Adding support for dag combiner to promote operations for profit. This requires target specific queries. For example, x86 should promote i16 to i32 when it does not impact load folding. 
x86 support is off by default. It can be enabled with -promote-16bit.

Work in progress.
