2013-04-12ARM: Correct printing of pre-indexed operands.Quentin Colombet
According to the ARM reference manual, constant offsets are mandatory for pre-indexed addressing modes. The MC disassembler was not obeying this when the offset is 0. It was producing instructions like: str r0, [r1]!. Correct syntax is: str r0, [r1, #0]!. This change modifies the dumping of operands so that the offset is always printed, regardless of its value, when pre-indexed addressing mode is used. Patch by Mihail Popa <Mihail.Popa@arm.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179398 91177308-0d34-0410-b5e6-96231b3b80d8

This patch replaces the hard coded GPR pair [R0, R1] of Intrinsic:arm_ldrexd and [R2, R3] of Intrinsic:arm_strexd with even/odd GPRPair reg class. Similar to the lowering of atomic_64 operation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168207 91177308-0d34-0410-b5e6-96231b3b80d8

Next step in the ongoing saga of NEON load/store assmebly parsing. Handle VLD1 instructions that take a two-register register list. Adjust the instruction definitions to only have the single encoded register as an operand. The super-register from the pseudo is kept as an implicit def, so passes which come after pseudo-expansion still know that the instruction defines the other subregs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142670 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-03ARM refactoring assembly parsing of memory address operands.Jim Grosbach
Memory operand parsing is a bit haphazzard at the moment, in no small part due to the even more haphazzard representations of memory operands in the .td files. Start cleaning that all up, at least a bit. The addressing modes in the .td files will be being simplified to not be so monolithic, especially with regards to immediate vs. register offsets and post-indexed addressing. addrmode3 is on its way with this patch, for example. This patch is foundational to enable going back to smaller incremental patches for the individual memory referencing instructions themselves. It does just enough to get the basics in place and handle the "make check" regression tests we already have. Follow-up work will be fleshing out the details and adding more robust test cases for the individual instructions, starting with ARM mode and moving from there into Thumb and Thumb2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136845 91177308-0d34-0410-b5e6-96231b3b80d8
