* Implement support for custom target specific asm parsing of operands.Bruno Cardoso Lopes2011-02-072-3/+268
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Motivation: Improve the parsing of not usual (different from registers or immediates) operand forms. This commit implements only the generic support. The ARM specific modifications will come next. A table like the one below is autogenerated for every instruction containing a 'ParserMethod' in its AsmOperandClass static const OperandMatchEntry OperandMatchTable[20] = { /* Mnemonic, Operand List Mask, Operand Class, Features */ { "cdp", 29 /* 0, 2, 3, 4 */, MCK_Coproc, Feature_IsThumb|Feature_HasV6 }, { "cdp", 58 /* 1, 3, 4, 5 */, MCK_Coproc, Feature_IsARM }, A matcher function very similar (but lot more naive) to MatchInstructionImpl scans the table. After the mnemonic match, the features are checked and if the "to be parsed" operand index is present in the mask, there's a real match. Then, a switch like the one below dispatch the parsing to the custom method provided in 'ParseMethod': case MCK_Coproc: return TryParseCoprocessorOperandName(Operands); git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125030 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | The vld1-lane, vld1-dup and vst1-lane instructions do not yet support using post-increment versions, but all the rest of the NEON load/store instructions should be handled now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125014 91177308-0d34-0410-b5e6-96231b3b80d8
* Change VLD3/4 and VST3/4 for quad registers to not update the address register.Bob Wilson2011-02-073-65/+89
| | | | | | | | | | | | These operations are expanded to pairs of loads or stores, and the first one uses the address register update to produce the address for the second one. So far, the second load/store has also updated the address register, just for convenience, since that output has never been used. In anticipation of actually supporting post-increment updates for these operations, this changes the non-updating operations to use a non-updating load/store for the second instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125013 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach ARM/MC/ELF about gcc compatible reloc output to get past odd linkageJason W Kim2011-02-074-3/+265
| | | | | | | | | | | | | | | | | | | | failures with relocations. The code committed is a first cut at compatibility for emitted relocations in ELF .o. Why do this? because existing ARM tools like emitting relocs symbols as explicit relocations, not as section-offset relocs. Result is that with these changes, 1) relocs are now substantially identical what to gcc outputs. 2) larger apps (including many spec2k tests) compile, cross-link, and pass Added reminder fixme to tests for future conversion to .s form. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124996 91177308-0d34-0410-b5e6-96231b3b80d8

* Rewrite how the indirect call bonus is handled. This now works by:Eric Christopher2011-02-052-80/+130
| | | | | | | | | | | | | | | | | | a) Making it a per call site bonus for functions that we can move from indirect to direct calls. b) Reduces the bonus from 500 to 100 per call site. c) Subtracts the size of the possible newly inlineable call from the bonus to only add a bonus if we can inline a small function to devirtualize it. Also changes the bonus from a positive that's subtracted to a negative that's added.
