377a5d7751 Add an autoconf check for -retain-symbols-file and conditionalize 
use of that option with it. This eliminates an imprecise "Linux"
test, and should help support old versions of gold.

6a038be777 introduce a new CallGraphSCC class, and pass it around 
to CallGraphSCCPass's instead of passing around a
std::vector<CallGraphNode*>.  No functionality change,
but now we have a much tidier interface.

44087236da Fixed a bug in DisassembleN1RegModImmFrm() where a break stmt was missing for a 
case.  Also, the 0xFF hex literal involved in the shift for ESize64 should be
suffixed "ul" to preserve the shift result.

Implemented printHex*ImmOperand() by copying from ARMAsmPrinter.cpp and added a
test case for DisassembleN1RegModImmFrm()/printHex64ImmOperand().

3cc0200f74 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().

Original commit text:
Use a ValueMap not a std::map for the reason indicated
in the comment.  This was causing nondeterministic changes

58add81e7d 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.

f0457a82fa Refine the detection of seemingly infinitely recursive calls where the 
callee is expected to be expanded to something else by codegen, so that
normal infinitely recursive calls are still transformed.

e7d6812008 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

60db5321b6 Add JIT exception handling test. 
llvm-svn: 101455
 2010-04-16 09:04:28 +00:00

7ede9396f4 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.

d143bfe0a4 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.
