* Remove shift amount flavor. It isn't actually complete enough to Eli Friedman2009-07-214-5/+0
| | | | | | | | be useful, and it's currently unused. (Some issues: it isn't actually rich enough to capture the semantics on many architectures, and semantics can vary depending on the type being shifted.) llvm-svn: 76633

* whitespace cleanups, make the MipsAsmPrinter::doInitializationChris Lattner2009-07-211-14/+8
| | | | | | | | chain to the super class instead of initializing mangler directly. This gives it .file and module level inline asm support among other things. llvm-svn: 76593
* fix Sparc, SystemZ, and MSP430 to not override AsmPrinter::doInitialization.Chris Lattner2009-07-213-22/+0
| | | | | | | This eliminates redundancy setting up the mangler and adds support to them for module-level inline asm and a .file directive. llvm-svn: 76592

* Another rewriter bug exposed by recent coalescer changes. ↵Evan Cheng2009-07-211-23/+27
| | | | | | ReuseInfo::GetRegForReload() should make sure the "switched" register is in the desired register class. I'm surprised this hasn't caused more failures in the past. llvm-svn: 76558

* Move a bit more state over to the LLVMContext.Owen Anderson2009-07-215-43/+49
| | | | llvm-svn: 76533
* Add the following functions:Bill Wendling2009-07-211-0/+12
| | | | | | | | | | | | - SYSCALL (normal fast system call instruction) [0f 05] - SYSENTER (system call entry instruction) [0f 34] - SYSEXIT (system call exit instruction) [0f 35] - SYSEXIT64 (system call exit instruction to 64-bit user code) [REX.W 0f 35] - SYSRET (system call return instruction) [0f 07] Patch by Sean Callanan. llvm-svn: 76528
* Make the range calculations for addrecs to be more conservative,Dan Gohman2009-07-211-3/+9

* Add a comment to clarify why there isn't any code in this spot.Dan Gohman2009-07-201-0/+2
| | | | llvm-svn: 76505
* Remove the code that tried to evaluate whether (A pred B) is knownDan Gohman2009-07-201-42/+0
| | | | | | | by determining if (B pred (B-A)) is known, as it doesn't handle overflow correctly. llvm-svn: 76504
* Make sure a global matching asm 'i' constraint gets itsDale Johannesen2009-07-201-5/+2
| | | | | | | | | | flags set properly. (hasMemory is clearly irrelevant when matching 'i', I don't understand what this was supposed to be doing.) gcc.apple/asm-block-25.c (test passed before by accident, but generated code was wrong) llvm-svn: 76503
* Move stripping of bitcasts in inline asm argumentsDale Johannesen2009-07-202-12/+7
| | | | | | | to a place where it affects everything. Occurs only on calls AFAIK. llvm-svn: 76502

* Pass in the unfortunately named "LessPrivatePrefix" for theBill Wendling2009-07-205-5/+10
| | | | | | | | "LinkerPrivatePrefix". It seems to have been used in only one place before I started this "linker_private" business. I'm thinking that a rename is in order... llvm-svn: 76479
* Assembly and Bitcode support for unsigned/signed overflow flags andDan Gohman2009-07-206-4/+173

* Use TII->findCommutedOpIndices to find the commute operands (rather than ↵Evan Cheng2009-07-201-4/+8

* Change the casting of linkage types into a map. This makes this much more robustBill Wendling2009-07-201-3/+88
| | | | | | | as it no longer depends upon two different enums being kept in sync with each other. llvm-svn: 76465
* Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API asKevin Enderby2009-07-201-12/+0
| | | | | | | | | the parsing of the .dump and .load should be done in the assembly parser and not have any need for an MCStreamer API. Changed the code for now so these just produce an error saying these specific directives are not yet implemented since they are likely no longer used and may never need to be implemented. llvm-svn: 76462
* Add MCAsmLexer interface.Daniel Dunbar2009-07-203-8/+51
| | | | | | - This provides the AsmLexer interface to the target specific assembly parsers. llvm-svn: 76460
