2011-01-11McARM: Add more hard coded logic to SplitMnemonicAndCC to also split out theDaniel Dunbar
carry setting flag from the mnemonic. Note that this currently involves me disabling a number of working cases in arm_instructions.s, this is a hopefully short term evil which will be rapidly fixed (and greatly surpassed), assuming my current approach flies. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123238 91177308-0d34-0410-b5e6-96231b3b80d8

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

2010-12-09Add support for parsing ARM arithmetic instructions that update or don't updateKevin Enderby
the condition codes. Where the ones that do have an 's' suffix and the ones that don't don't have the suffix. The trick is if MatchInstructionImpl() fails we try again after adding a CCOut operand with the correct value and removing the 's' if present. Four simple test cases added for now, lots more to come. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121401 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-06The ARM AsmMatcher needs to know that the CCOut operand is a register value,Jim Grosbach
not an immediate. It stores either ARM::CPSR or reg0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121018 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-30* Add support for encoding t_addrmode_s2 and t_addrmode_s1. They are the same asBill Wendling
t_addrmode_s4, but with a different scaling factor. * Encode the Thumb1 load and store instructions. This involved a bit of refactoring (hi, Chris! :-). Some of the patterns became dead afterwards and were removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120482 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-30Add parsing for the Thumb t_addrmode_s4 addressing mode. This can almostBill Wendling
certainly be made more generic. But it does allow us to parse something like: ldr r3, [r2, r4] correctly in Thumb mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120408 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-17Proper encoding for VLDM and VSTM instructions. The register lists for theseBill Wendling
instructions have to distinguish between lists of single- and double-precision registers in order for the ASM matcher to do a proper job. In all other respects, a list of single- or double-precision registers are the same as a list of GPR registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119460 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-09Two types of instructions have register lists:Bill Wendling
* LDM, et al, uses a bit mask to indicate the register list. * VLDM, et al, uses a base register plus number. The LDM instructions may be non-contiguous, but the VLDM ones must be contiguous. Those are semantic checks that should be done later in the compiler. Also postpone the creation of the bit mask until it's needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118640 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-07In this context, a reglist is a reg.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118375 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-06Add support for parsing register lists. We can't use a bitfield to keep track ofBill Wendling
the registers, because the register numbers may be much greater than the number of bits available in the machine's register. I extracted the register list verification code out of the actual parsing of the registers. This made checking for errors much easier. It also limits the number of warnings that would be emitted for cascading infractions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118363 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-06Return the base register of a register list for the "getReg()" method. This isBill Wendling

2010-11-06Add a RegList (register list) object to ARMOperand. It will be used soon to holdBill Wendling
(surprise!) a list of registers. Register lists are consecutive, so we only need to record the start register plus the number of registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118351 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-03The MC code couldn't handle ARM LDR instructions with negative offsets:Bill Wendling
vldr.64 d1, [r0, #-32] The problem was with how the addressing mode 5 encodes the offsets. This change makes sure that the way offsets are handled in addressing mode 5 is consistent throughout the MC code. It involves re-refactoring the "getAddrModeImmOpValue" method into an "Imm12" and "addressing mode 5" version. But not to worry! The majority of the duplicated code has been unified. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118144 91177308-0d34-0410-b5e6-96231b3b80d8
