2011-06-27Teach one piece of scalarrepl to handle lifetime markers. When transforming anNick Lewycky
alloca that only holds a copy of a global and we're going to replace the users of the alloca with that global, just nuke the lifetime intrinsics. Part of PR10121. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133905 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-27Grow the X86FloatingPoint register map to hold 16 registers.Jakob Stoklund Olesen
This allows for more live scratch registers which is needed to handle live ST registers before return and inline asm instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133903 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-27Distinguish early clobber output operands from clobbered registers.Jakob Stoklund Olesen
Both become <earlyclobber> defs on the INLINEASM MachineInstr, but we now use two different asm operand kinds. The new Kind_Clobber is treated identically to the old Kind_RegDefEarlyClobber for now, but x87 floating point stack inline assembly does care about the difference. This will pop a register off the stack: asm("fstp %st" : : "t"(x) : "st"); While this will pop the input and push an output: asm("fst %st" : "=&t"(r) : "t"(x)); We need to know if ST0 was a clobber or an output operand, and we can't depend on <dead> flags for that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133902 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-27Decode and pretty print inline asm operand descriptors.Jakob Stoklund Olesen
The INLINEASM MachineInstrs have an immediate operand describing each original inline asm operand. Decode the bits in MachineInstr::print() so it is easier to read: INLINEASM <es:rorq $1,$0>, $0:[regdef], %vreg0<def>, %vreg1<def>, $1:[imm], 1, $2:[reguse] [tiedto:$0], %vreg2, %vreg3, $3:[regdef-ec], %EFLAGS<earlyclobber,imp-def> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133901 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-25PTX: Reverting implementation of i8.Dan Bailey
The .b8 operations in PTX are far more limiting than I first thought. The mov operation isn't even supported, so there's no way of converting a .pred value into a .b8 without going via .b16, which is not sensible. An improved implementation needs to use the fact that loads and stores automatically extend and truncate to implement support for EXTLOAD and TRUNCSTORE in order to correctly support boolean values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133873 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-24The Neon VCVT (between floating-point and fixed-point, Advanced SIMD) Chad Rosier
instructions can be used to match combinations of multiply/divide and VCVT (between floating-point and integer, Advanced SIMD). Basically the VCVT immediate operand that specifies the number of fraction bits corresponds to a floating-point multiply or divide by the corresponding power of 2. For example, VCVT (floating-point to fixed-point, Advanced SIMD) can replace a combination of VMUL and VCVT (floating-point to integer) as follows: Example (assume d17 = <float 8.000000e+00, float 8.000000e+00>): vmul.f32 d16, d17, d16 vcvt.s32.f32 d16, d16 becomes: vcvt.s32.f32 d16, d16, #3 Similarly, VCVT (fixed-point to floating-point, Advanced SIMD) can replace a combinations of VCVT (integer to floating-point) and VDIV as follows: Example (assume d17 = <float 8.000000e+00, float 8.000000e+00>): vcvt.f32.s32 d16, d16 vdiv.f32 d16, d17, d16 becomes: vcvt.f32.s32 d16, d16, #3 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133813 91177308-0d34-0410-b5e6-96231b3b80d8
