* Proper encoding for VLDM and VSTM instructions. The register lists for theseBill Wendling2010-11-175-11/+71
| | | | | | | | | | instructions have to distinguish between lists of single- and double-precision registers in order for the ASM matcher to do a proper job. In all other respects, a list of single- or double-precision registers are the same as a list of GPR registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119460 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a layering violation: hasConstantValue, which is part of the PHINodeDuncan Sands2010-11-174-69/+47
| | | | | | | | | | | | | | | class, uses DominatorTree which is an analysis. This change moves all of the tricky hasConstantValue logic to SimplifyInstruction, and replaces it with a very simple literal implementation. I already taught users of hasConstantValue that need tricky stuff to use SimplifyInstruction instead. I didn't update InlineFunction because the IR looks like it might be in a funky state at the point it calls hasConstantValue, which makes calling SimplifyInstruction dangerous since it can in theory do a lot of tricky reasoning. This may be a pessimization, for example in the case where all phi node operands are either undef or a fixed constant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119459 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix emergency spilling in LiveIntervals::spillPhysRegAroundRegDefsUses.Jakob Stoklund Olesen2010-11-161-22/+23
| | | | | | | | | | | | | | Always spill the full representative register at any point where any subregister is live. This fixes PR8620 which caused the old logic to get confused and not spill anything at all. The fundamental problem here is that the coalescer is too aggressive about physical register coalescing. It sometimes makes it impossible to allocate registers without these emergency spills. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119375 91177308-0d34-0410-b5e6-96231b3b80d8

* This is the first step in adding sane error handling support to LLVMSystem.Michael J. Spencer2010-11-168-368/+359
| | | | | | | | | | | | | | | | | The system API's will be shifted over to returning an error_code, and returning other return values as out parameters to the function. Code that needs to check error conditions will use the errc enum values which are the same as the posix_errno defines (EBADF, E2BIG, etc...), and are compatable with the error codes in WinError.h due to some magic in system_error. An example would be: if (error_code ec = KillEvil("Java")) { // error_code can be converted to bool. handle_error(ec); } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119360 91177308-0d34-0410-b5e6-96231b3b80d8
