2013-02-15Remove a final dependency on the form field in tablegen; which is a remnantReed Kotler
of the old jit and which we don't intend to support in mips16 or micromips. This dependency is for the testing of whether an instruction is a pseudo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175297 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-15AArch64: add branch fixup pass.Tim Northover
This is essentially a stripped-down version of the ConstandIslands pass (which always had these two functions), providing just the features necessary for correctness. In particular there needs to be a way to resolve the situation where a conditional branch's destination block ends up out of range. This issue crops up when self-hosting for AArch64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175269 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-15Don't make assumptions about the mangling of static functions in extern "C"Rafael Espindola
blocks. We still don't have consensus if we should try to change clang or the standard, but llvm should work with compilers that implement the current standard and mangle those functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175267 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-15AArch64: remove ConstantIsland pass & put literals in separate section.Tim Northover
This implements the review suggestion to simplify the AArch64 backend. If we later discover that we *really* need the extra complexity of the ConstantIslands pass for performance reasons it can be resurrected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175258 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-15AArch64: refactor frame handling to use movz/movk for overlarge offsets.Tim Northover
In the near future litpools will be in a different section, which means that any access to them is at least two instructions. This makes the case for a movz/movk pair (if total offset <= 32-bits) even more compelling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175257 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-14The ARM NEON vector compare instructions take three arguments. However, the Joel Jones

2013-02-14R600/SI: Fix int_SI_fs_interp_constantMichel Danzer
The important fix is that the constant interpolation value is stored in the parameter slot P0, which is encoded as 2. In addition, drop the SI_INTERP_CONST pseudo instruction, pass the parameter slot as an operand to V_INTERP_MOV_F32 instead of hardcoding it there, and add a special operand class for the parameter slots for type checking and pretty printing.
