2009-08-15An overhaul of the exception handling code. This is arguably more correct thanBill Wendling
what was there before. In "no FP mode", we weren't generating labels and unwind table entries after each "push" instruction. While more than likely "okay", it's not technically correct. The major thing was that the ordering of when to define a new CFA register and at what offset wasn't correct. This would cause the exception handling to fail in ways most miserable to users. I also cleaned up some code a bit. There's one function which has a "return" at the beginning, so it's never used. Should I just remove it? :-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79139 91177308-0d34-0410-b5e6-96231b3b80d8

blocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79132 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-15Change allowsUnalignedMemoryAccesses to take type argument since some targetsEvan Cheng
support unaligned mem access only for certain types. (Should it be size instead?) ARM v7 supports unaligned access for i16 and i32, some v6 variants support it as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79127 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-15Refine EarlyClobber assert in register scavenger.Jakob Stoklund Olesen
It is legal for an inline asm operand to use an earlyclobber register if the use operand is tied to the earlyclobber operand. The issue is discussed here: http://gcc.gnu.org/ml/gcc/1999-04n/msg00431.html We should perhaps let only the machine code verifier worry about these finer details. EarlyClobber operands are not really interesting to the scavenger. This fixes PR4528 for the third time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79122 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-15the .eh_frame sections we generate need to be writable (whichChris Lattner
is why they are datarel). This should fix PR4724, and is fallout from r78890. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79111 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-15Revert a few changes that were done in 78603.Sanjiv Gupta
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
2009-08-15Don't setCalleeSavedInfoValid() until spills are interted.Jakob Stoklund Olesen
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

2009-08-15Add support for the PowerPC 64-bit SVR4 ABI.Tilmann Scheller
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
2009-08-15Update LocalRewriter::DistanceMap when inserting stack loads.Jakob Stoklund Olesen
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

2009-08-15use XCore-specific section with xcore specific cp/dp flags to restore Chris Lattner

2009-08-14Allow targets to specify their choice of calling conventions perAnton Korobeynikov

2009-08-14llvm-mc: When handling a .set, make sure to print subsequent references to theDaniel Dunbar
symbol as the symbol name itself, not the expression it was defined to. These have different semantics due to the quirky .set behavior (which absolutizes an expression that would otherwise be treated as a relocation). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79025 91177308-0d34-0410-b5e6-96231b3b80d8
