* Added the B9.3.19 SUBS PC, LR, #imm (Thumb2) system instruction.Kevin Enderby2013-07-31
| | | | | | | | | | | | While the .td entry is nice and all, it takes a pretty gross hack in ARMAsmParser::ParseInstruction() because of handling of other "subs" instructions to get it to match.

* [SystemZ] Add NRK, ORK and XRKRichard Sandiford2013-07-19
| | | | | | | | | | | | | The atomic tests assume the two-operand forms, so I've restricted them to z10. Running and-01.ll, or-01.ll and xor-01.ll for z196 as well as z10 shows why using convertToThreeAddress() is better than exposing the three-operand forms first and then converting back to two operands where possible (which is what I'd originally tried). Using the three-operand form first stops us from taking advantage of NG, OG and XG for spills. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186683 91177308-0d34-0410-b5e6-96231b3b80d8
* [SystemZ] Start adding z196 and zEC12 supportRichard Sandiford2013-07-19
| | | | | | | | | | | | | This first step just adds definitions for SLLK, SRLK and SRAK. The next patch will actually make use of them during codegen. insn-bad.s tests that some form of error is reported when using these instructions on z10. More work is needed to get the "instruction requires: distinct-ops" that we'd ideally like, so I've stubbed that part out for now. I'll come back and make it mandatory once the necessary changes are in. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186680 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM: delete two tests now integrated into the larger filesTim Northover2013-07-19
| | | | | | | | Somehow forgot to git rm these two files. I believe I left the remaining invalid* tests intentionally, though whether my reasons were sound is a different matter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186663 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM: remove invalid invalid testsTim Northover2013-07-19
| | | | | | | | | | | The tests were checking for barriers which the ARM ARM says they must execute as a full system DMB/DSB, rather than that they're UNDEFINED and LLVM does in fact represent them. The tests happened to be passing because they were using a non-versioned ARM triple which didn't have *any* DMB/DSB instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186662 91177308-0d34-0410-b5e6-96231b3b80d8
* Improve llvm-mc disassembler mode and refactor ARM tests to use itTim Northover2013-07-19
| | | | | | | | | | | | | | | | | | This allows "llvm-mc -disassemble" to accept two new features: + Using comma as a byte separator + Grouping bytes with '[' and ']' pairs. The behaviour outside a [...] group is unchanged. But within the group once llvm-mc encounters a true error, it stops rather than trying to resynchronise the stream at the next byte. This is more useful for disassembly tests, where we have an almost-instruction in mind and don't care what the misaligned interpretation would be. Particularly if it means llvm-mc won't actually see the next intended almost-instruction. As a side effect, this means llvm-mc can disassemble its own -show-encoding output if copy-pasted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186661 91177308-0d34-0410-b5e6-96231b3b80d8

* [SystemZ] Allow 8-bit operands to RISBGRichard Sandiford2013-07-11
| | | | | | | | | | | | | RISBG has three 8-bit operands (I3, I4 and I5). I'd originally restricted all three to 6 bits, since that's the only range we intended to use at the time. However, the top bit of I4 acts as a "zero" flag for RISBG, while the top bit of I3 acts as a "test" flag for RNSBG & co. This patch therefore allows them to have the full 8-bit range. I've left the fifth operand as a 6-bit value for now since the upper 2 bits have no defined meaning. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186070 91177308-0d34-0410-b5e6-96231b3b80d8

* Update the X86 disassembler to use xacquire and xrelease when appropriate.Kevin Enderby2013-06-20
| | | | | | | | | | | | | | | | | | This is a bit tricky as the xacquire and xrelease hints use the same bytes, 0xf2 and 0xf3, as the repne and rep prefixes. Fortunately llvm has different llvm MCInst Opcode enums for rep/xrelease and repne/xacquire. So to make this work a boolean was added the InternalInstruction struct as part of the Prefix state which is set with the added logic in readPrefixes() when decoding an instruction to determine if these prefix bytes are to be disassembled as xacquire or xrelease. Then we let the matcher pick the normal prefix instructionID and we change the Opcode after that when it is set into the MCInst being created. rdar://11019859 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184490 91177308-0d34-0410-b5e6-96231b3b80d8
