2011-03-31Apply again changes to support ARM memory asm parsing. I removedBruno Cardoso Lopes
all LDR/STR changes and left them to a future patch. Passing all checks now. - Implement asm parsing support for LDRT, LDRBT, STRT, STRBT and fix the encoding wherever is possible. - Add a new encoding bit to describe the index mode used and teach printAddrMode2Operand to check by the addressing mode which index mode to print. - Testcases git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128689 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-31Revert "- Implement asm parsing support for LDRT, LDRBT, STRT, STRBT and"Matt Beaumont-Gay

2011-03-30- Implement asm parsing support for LDRT, LDRBT, STRT, STRBT andBruno Cardoso Lopes
{STR,LDC}{2}_PRE. - Fixed the encoding in some places. - Some of those instructions were using am2offset and now use addrmode2. Codegen isn't affected, instructions which use SelectAddrMode2Offset were not touched. - Teach printAddrMode2Operand to check by the addressing mode which index mode to print. - This is a work in progress, more work to come. The idea is to change places which use am2offset to use addrmode2 instead, as to unify assembly parser. - Add testcases for assembly parser git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128585 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-14Fix encoding and add parsing support for the arm/thumb CPS instruction:Bruno Cardoso Lopes
- Add custom operand matching for imod and iflags. - Rename SplitMnemonicAndCC to SplitMnemonic since it splits more than CC from mnemonic. - While adding ".w" as an operand, don't change "Head" to avoid passing the wrong mnemonic to ParseOperand. - Add asm parser tests. - Add disassembler tests just to make sure it can catch all cps versions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125489 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-12AsmMatcher custom operand parser failure enhancements.Jim Grosbach
Teach the AsmMatcher handling to distinguish between an error custom-parsing an operand and a failure to match. The former should propogate the error upwards, while the latter should continue attempting to parse with alternative matchers. Update the ARM asm parser accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125426 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-07Remove the MCR asm parser hack and start using the custom target specific asmBruno Cardoso Lopes
parsing of operands introduced in r125030. As a small note, besides using a more generic approach we can also have more descriptive output when debugging llvm-mc, example: mcr p7, #1, r5, c1, c1, #4 note: parsed instruction: ['mcr', <ARMCC::al>, <coprocessor number: 7>, 1, <register 73>, <coprocessor register: 1>, <coprocessor register: 1>, 4] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125052 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-13Add support to the ARM MC infrastructure to support mcr and friends. This ↵Owen Anderson
requires supporting the symbolic immediate names used for these instructions, fixing their pretty-printers, and adding proper encoding information for them.

2011-01-13Model :upper16: and :lower16: as ARM specific MCTargetExpr. This is a stepEvan Cheng
in the right direction. It eliminated some hacks and will unblock codegen work. But it's far from being done. It doesn't reject illegal expressions, e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123369 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-13Add a FIXME and two asserts for now in the ARMAsmParser when it sees .code 16 orKevin Enderby
.code 32 if the TargetMachine's isThumb() boolean does not match. The correct fix is to switch ARM subtargets at that point and is tracked by rdar://8856789 which is bigger task. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123353 91177308-0d34-0410-b5e6-96231b3b80d8
