2010-04-16Use a simpler data structure to calculate the least recently used register ↵Jakob Stoklund Olesen
in RegAllocLocal. This makes the local register allocator about 20% faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101574 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-16building on the new CallGraphSCC abstraction, teach CallGraphSCCPassManager Chris Lattner
to keep the node entries in scc_iterator up to date instead of dangling as the SCC mutates. This is a really terrible problem which was causing -g to affect codegen because it would permute the memory image of the compiler process. Thanks to Dale for expertly hunting it down. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101565 91177308-0d34-0410-b5e6-96231b3b80d8

No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101562 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-16introduce a new CallGraphSCC class, and pass it aroundChris Lattner
to CallGraphSCCPass's instead of passing around a std::vector<CallGraphNode*>. No functionality change, but now we have a much tidier interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101558 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-16Fixed a bug in DisassembleN1RegModImmFrm() where a break stmt was missing for aJohnny Chen
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(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101557 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-16In the same spirit of r101524, which removed the assert() from ↵Johnny Chen
printAddrMode2OffsetOperand(), this patch removes the assert() from printAddrMode3OffsetOperand() and adds a test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101529 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-16Multiclass LdStCop was using pre-UAL syntax LDC<c>L for the L fragment. ChangedJohnny Chen
to the UAL syntax of LDCL<c>, instead. Add a test case for this change which also tests the removal of assert() from printAddrMode2OffsetOperand(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101527 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-16Disable inlining of recursive calls. It can complicate tailcallelim andDan Gohman
dependent analyses, and increase code size, so doing it profitably would require more complex heuristics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101471 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-16The JIT calls TidyLandingPads to tidy up the landing pads. However, because theBill Wendling
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101453 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-16Adding support for dag combiner to promote operations for profit. This ↵Evan Cheng
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101448 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-15Avoid sinking machine instructions into a loop.Jakob Stoklund Olesen
MachineLoopInfo is already available when MachineSinking runs, so the check is free. There is no test case because it would require a critical edge into a loop, and CodeGenPrepare splits those. This check is just to be extra careful. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101420 91177308-0d34-0410-b5e6-96231b3b80d8
