2010-12-14The tLDR et al instructions were emitting either a reg/reg or reg/immBill Wendling
instruction based on the t_addrmode_s# mode and what it returned. There is some obvious badness to this. In particular, it's hard to do MC-encoding when the instruction may change out from underneath you after the t_addrmode_s# variable is finally resolved. The solution is to revert a long-ago change that merged the reg/reg and reg/imm versions. There is the addition of several new addressing modes. They no longer have extraneous operands associated with them. I.e., if it's reg/reg we don't have to have a dummy zero immediate tacked on to the SDNode. There are some obvious cleanups here, which will happen shortly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121747 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-14Second attempt at make Thumb2 LEAs pseudos. This time, perform the lowering ↵Owen Anderson

2010-12-13Remove the rest of the *_sfp Neon instruction patterns.Bob Wilson
Use the same COPY_TO_REGCLASS approach as for the 2-register *_sfp instructions. This change made a big difference in the code generated for the CodeGen/Thumb2/cross-rc-coalescing-2.ll test: The coalescer is still doing a fine job, but some instructions that were previously moved outside the loop are not moved now. It's using fewer VFP registers now, which is generally a good thing, so I think the estimates for register pressure changed and that affected the LICM behavior. Since that isn't obviously wrong, I've just changed the test file. This completes the work for Radar 8711675. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121730 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-13Make Thumb2 LEA-like instruction into pseudos, which map down to ADR. ↵Owen Anderson
Provide correct fixups for Thumb2 ADR, which is _of course_ different from ARM ADR fixups, or any other Thumb2 fixup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121721 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-13In Thumb2, direct branches can be encoded as either a "short" conditional ↵Owen Anderson
branch with a null predicate, or as a "long" direct branch. While the mnemonics are the same, they encode the branch offset differently, and the Darwin assembler appears to prefer the "long" form for direct branches. Thus, in the name of bitwise equivalence, provide encoding and fixup support for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121710 91177308-0d34-0410-b5e6-96231b3b80d8

Remove the previous header. I don't think we need to expose to end users that we use TableGen to produce our version of arm_neon.h, and that header was also using doubleslash comments which could be a problem when using it in strict C89 compilations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121390 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-09The BLX instruction is encoded differently than the BL, because why not? InBill Wendling
particular, the immediate has 20-bits of value instead of 21. And bit 0 is '0' always. Going through the BL fixup encoding was trashing the "bit 0 is '0'" invariant. Attempt to get the encoding at slightly more correct with this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121336 91177308-0d34-0410-b5e6-96231b3b80d8
