Rafael Espindola 08600bcf65 Use the dwarf->llvm mapping to print register names in the cfi
directives.

Fixes PR9826.

Rafael Espindola ddffa0e160 Introduce the DwarfRegAlias class for declaring that two registers have the
same dwarf number. This will be used for creating a dwarf number to register
mapping.

The only case that needs this so far is the XMM/YMM registers that unfortunately
do have the same numbers.

Rafael Espindola ea8ca34e3a Mark the 32 bit registers as invalid in 64 bit mode. In 64 bit mode they are
subregisters of the 64 bit ones.

Rafael Espindola 595fd7a058 Remove the DwarfNumbers from the subregisters. They should use DW_OP_bit_piece
and for now the generic dwarf emission will automatically use the superregister
numbers.

John McCall 7d84ece09b On Darwin ARM, set the UNWIND_RESUME libcall to _Unwind_SjLj_Resume.
This is important for the correct lowering of unwind instructions
(which doesn't matter at all) and llvm.eh.resume calls (which does).

Take 2, now with more basic competence.

Rafael Espindola fd75d45b88 Remove the dwarf numbers from the D registers. They don't have dwarf numbers
and should probably be encoded as

Bruno Cardoso Lopes 325110f30d Add support for ARM ldrexd/strexd intrinsics. They both use i32 register pairs
to load/store i64 values. Since there's no current support to explicitly
declare such restrictions, implement it by using specific hardcoded register
pairs during isel.

Eric Christopher d00e8ad803 Implement the 'M' output modifier for arm inline asm. This is fairly
register allocation dependent and will occasionally break. WIP in the
register allocator to model paired/etc registers.

Bruno Cardoso Lopes 787dfadc7c ARM asm parser wasn't able to parse a "mov" instruction while in Thumb
mode (only the "mov.w" variant). Now, when parsing "mov" in thumb mode,
default to the Thumb 1 versions/encodings.

Cameron Zwarich 75d99e4b70 Add a GR32_NOREX_NOSP register class and fix a bug where getMatchingSuperRegClass()
was saying that the matching superregister class of GR32_NOREX in GR64_NOREX_NOSP
is GR64_NOREX, which drops the NOSP constraint. This fixes PR10032.

2011-05-26 02:44:56 +00:00
Eli Friedman c70355195c Rewrite fast-isel integer cast handling to handle more cases, and to be simpler and more consistent.
The practical effects here are that x86-64 fast-isel can now handle trunc from i8 to i1, and ARM fast-isel can handle many more constructs involving integers narrower than 32 bits (including loads, stores, and many integer casts).
