2011-09-14Thumb2 assembly parsing for MOV in IT block.Jim Grosbach
Select the right 16 vs. 32 bit encoding in an IT block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139714 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-14ARM fix assembly parser handling of ranges in register lists.Jim Grosbach
Clean up register list handling in general a bit to explicitly check things like all the registers being from the same register class. rdar://8883573 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139707 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-13Teach the Thumb ASM parser that BKPT is allowed in IT blocks, even though it ↵Owen Anderson
is always executed unconditionally. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139610 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-10Thumb2 parsing and encoding for MOV(immediate).Jim Grosbach
Some aliases for MOV(register) also to keep existing T1 tests happy when run in thumbv7 mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139440 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-09Thumb unconditional branches are allowed in IT blocks, and therefore should ↵Owen Anderson
have a predicate operand, unlike conditional branches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139415 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-08Thumb2 assembly parsing and encoding for LDRD(immediate).Jim Grosbach
Refactor operand handling for STRD as well. Tests for that forthcoming. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139322 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-08Thumb2 assembly parsing and encoding for LDR pre-indexed w/ writeback.Jim Grosbach
Adjust encoding of writeback load/store instructions to better reflect the way the operand types are represented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139270 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-07Thumb2 assembly parsing and encoding for LDRBT.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139267 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-07Thumb2 assembly parsing and encoding for LDR(register).Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139264 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-07Thumb2 parsing and encoding for LDR(immediate).Jim Grosbach
The immediate offset of the non-writeback i8 form (encoding T4) allows negative offsets only. The positive offset form of the encoding is the LDRT instruction. Immediate offsets in the range [0,255] use encoding T3 instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139254 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-07Thumb2 parsing and encoding for LDMIA.Jim Grosbach
Choose 32-bit vs. 16-bit encoding when there's no .w suffix in post-processing as match classes are insufficient to handle the context-sensitiveness of the writeback operand's legality for the 16-bit encodings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139242 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139232 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-06Thumb2 parsing and encoding for CLREX.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139172 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-06ARM .code directive should always go to the streamer.Jim Grosbach
Even if there's no mode switch performed, the .code directive should still be sent to the output streamer. Otherwise, for example, an output asm stream is not equivalent to the input stream which generated it (a dependency on the input target triple arm vs. thumb is introduced which was not originally there). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139155 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-02Thumb2 parsing and encoding of B instruction.Jim Grosbach
Tweak handling of IT blocks a bit to enable this. The differentiation between B and Bcc needs special sauce. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139049 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-01ARM 'rscs' mnemonic is carry-setting 'rsc', not 'rs' with a 'cs' condition code.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138952 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-01t2Bcc is allowed to have a predicate without a preceding IT instruction.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138946 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138922 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-31Thumb2 t2Bcc should encode as t2B when condition is 'always'.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138898 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-31Remove FIXME. Thumb2 MOV instruction will use separate custom tricks.Jim Grosbach
When we want encoding T3 (the wide encoding), we can explicitly check for that and twiddle the CanAcceptCarrySet accordingly. For now, just correctly handle encodings T1 and T2 when in Thumb2 mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138879 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-31tBcc is OK to be predicated in Thumb2 outside of IT blocks (obviously).Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138873 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-31Tweak Thumb1 ADD encoding selection a bit.Jim Grosbach
When the destination register of an add immediate instruction is explicitly specified, encoding T1 is preferred, else encoding T2 is preferred. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138862 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-29Thumb2 parsing and encoding for IT blocks.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138773 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138754 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-29Add support for parsing #-0 on non-memory-operand immediate values, and add ↵Owen Anderson
a testcase that necessitates it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138739 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-26ARM assembly parsing tweak for pldw.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138669 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-26Thumb2 assembler parsing and encoding of IT instruction.Jim Grosbach
This handles only the handling of the IT instruction itself, not the processing and validation of the instructions in the IT block. That's next, and will include encoding tests for IT itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138665 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-26invalid-LDR_PRE-arm.txt was already passing, but for the wrong reasons. We ↵Owen Anderson
were failing to specify enough fixed bits of LDR_PRE/LDRB_PRE, resulting in decoding conflicts. Separate them into immediate vs. register versions, allowing us to specify the necessary fixed bits. This in turn results in the test being decoded properly, and being rejected as UNPREDICTABLE rather than a hard failure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138653 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-24Thumb .n mnemonic qualifiers can be ignored for now.Jim Grosbach
We'll need to pay attention to them when we start getting more serious about the details of parsing thumb2 assembly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138500 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-24Thumb parsing and encoding for SUB (SP minu immediate).Jim Grosbach
Fix FiXME in test file. Remove FIXME for SUB (SP minus register) since that form is Thumb2 only. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138494 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-24Thumb parsing and encoding support for ADD SP instructions.Jim Grosbach
Fix the test FIXME and add parsing support for the ADD (SP plus immediate) and ADD (SP plus register) instruction forms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138488 91177308-0d34-0410-b5e6-96231b3b80d8
