* Revert a few changes that were done in 78603.Sanjiv Gupta2009-08-152-14/+15
| | | | | | | | | | PIC16DebugInfo currently rely on NameStr of composite type descriptors to uniquely identify debug info for two aggregate type decls with same name. This implementation will change when we have MDNodes based debug info implemenatation in place git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79097 91177308-0d34-0410-b5e6-96231b3b80d8
* Don't setCalleeSavedInfoValid() until spills are interted.Jakob Stoklund Olesen2009-08-152-2/+12
| | | | | | | | | | In a naked function, the flag is never set and getPristineRegs() returns an empty list. That means naked functions are able to clobber callee saved registers, but that is the whole point of naked functions. This fixes PR4716. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79096 91177308-0d34-0410-b5e6-96231b3b80d8
* Allow double defs in the machine code verifier after the addPreRegAlloc passes.Jakob Stoklund Olesen2009-08-151-1/+1

* Move XCore AsmPrinter to XCore/AsmPrinter directory.Richard Osborne2009-08-157-10/+34
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79094 91177308-0d34-0410-b5e6-96231b3b80d8

* Add XFAIL test case for a scavenger assert.Jakob Stoklund Olesen2009-08-151-0/+20
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79092 91177308-0d34-0410-b5e6-96231b3b80d8
* Add support for the PowerPC 64-bit SVR4 ABI.Tilmann Scheller2009-08-159-72/+361
| | | | | | | | | | | | | | | | | | The Link Register is volatile when using the 32-bit SVR4 ABI. Make it possible to use the 64-bit SVR4 ABI. Add non-volatile registers for the 64-bit SVR4 ABI. Make sure r2 is a reserved register when using the 64-bit SVR4 ABI. Update PPCFrameInfo for the 64-bit SVR4 ABI. Add FIXME for 64-bit Darwin PPC. Insert NOP instruction after direct function calls. Emit official procedure descriptors. Create TOC entries for GlobalAddress references. Spill 64-bit non-volatile registers to the correct slots. Only custom lower VAARG when using the 32-bit SVR4 ABI. Use simple VASTART lowering for the 64-bit SVR4 ABI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79091 91177308-0d34-0410-b5e6-96231b3b80d8
* Update LocalRewriter::DistanceMap when inserting stack loads.Jakob Stoklund Olesen2009-08-152-0/+28
| | | | | | | | In the included test case, a stack load was not included in DistanceMap. That caused TransferDeadness to ignore the instruction, leading to a scavenger assert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79090 91177308-0d34-0410-b5e6-96231b3b80d8
