2010-02-25Revert r97064. Duncan pointed out that bitcasts are defined inDan Gohman
terms of store and load, which means bitcasting between scalar integer and vector has endian-specific results, which undermines this whole approach. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97137 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-25Truncate from i64 to i32 is "free" on x86-32, because it involves Dan Gohman

2010-02-25Large stack frame patch for the CellSPU: handle stack frames that exceed 8176Scott Michel
(511*16) bytes register displacement (D-form). NOTE: This is a potential headache, given the SPU's local core limitations, allowing the software developer to commit stack overrun suicide unknowingly. Also, large SPU stack frames will cause code size explosion. But, one presumes that the software developer knows what they're doing... Contributed by Kalle.Raiskila@nokia.com, edited slightly before commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97091 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Create a stack frame on ARM whenJakob Stoklund Olesen
- Function uses all scratch registers AND - Function does not use any callee saved registers AND - Stack size is too big to address with immediate offsets. In this case a register must be scavenged to calculate the address of a stack object, and the scavenger needs a spare register or emergency spill slot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97071 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Check for comparisons of +/- zero when optimizing less-than-or-equal andBob Wilson
greater-than-or-equal SELECT_CCs to NEON vmin/vmax instructions. This is only allowed when UnsafeFPMath is set or when at least one of the operands is known to be nonzero. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97065 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Make getTypeSizeInBits work correctly for array types; it should returnDan Gohman
the number of value bits, not the number of bits of allocation for in-memory storage. Make getTypeStoreSize and getTypeAllocSize work consistently for arrays and vectors. Fix several places in CodeGen which compute offsets into in-memory vectors to use TargetData information. This fixes PR1784. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97064 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Adding function "lookupGCCName" to MBlazeIntrinsicInfoWesley Peck
Adding the function "lookupGCCName" to the MBlazeIntrinsicInfo class to support the Clang MicroBlaze target. Additionally, minor fixes which remove some unused PIC code (PIC is not supported yet in the MicroBlaze backend) and removed some unused variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97054 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-24When forming SSE min and max nodes for UGE and ULE comparisons, it'sDan Gohman
necessary to swap the operands to handle NaN and negative zero properly. Also, reintroduce logic for checking for NaN conditions when forming SSE min and max instructions, fixed to take into consideration NaNs and negative zeros. This allows forming min and max instructions in more cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97025 91177308-0d34-0410-b5e6-96231b3b80d8
