LLVM backend for 6502
3b52084af8
Summary: This patch re-uses the implementation of 'llvm-mc -show-inst' and makes it available to llc as 'llc -asm-show-inst'. This is necessary to test parts of MIPS32r6/MIPS64r6 without resorting to 'llc -filetype=obj' tests. For example, on MIPS32r2 and earlier we use the 'jr $rs' instruction for indirect branches and returns. On MIPS32r6, we no longer have 'jr $rs' and use 'jalr $zero, $rs' instead. The catch is that, on MIPS32r6, 'jr $rs' is an alias for 'jalr $zero, $rs' and is the preferred way of writing this instruction. As a result, all MIPS ISA's emit 'jr $rs' in their assembly output and the assembler encodes this to different opcodes according to the ISA. Using this option, we can check that the MCInst really is a JR or a JALR by matching the emitted comment. This removes the need for a 'llc -filetype=obj' test.
