David Woodhouse f71254859e [x86] Fix retq/retl handling in 64-bit mode This finishes the job started in r198756, and creates separate opcodes for 64-bit vs. 32-bit versions of the rest of the RET instructions too. LRETL/LRETQ are interesting... I can't see any justification for their existence in the SDM. There should be no 'LRETL' in 64-bit mode, and no need for a REX.W prefix for LRETQ. But this is what GAS does, and my Sandybridge CPU and an Opteron 6376 concur when tested as follows: asm __volatile__("pushq $0x1234\nmovq $0x33,%rax\nsalq $32,%rax\norq $1f,%rax\npushq %rax\nlretl $8\n1:"); asm __volatile__("pushq $1234\npushq $0x33\npushq $1f\nlretq $8\n1:"); asm __volatile__("pushq $0x33\npushq $1f\nlretq\n1:"); asm __volatile__("pushq $0x1234\npushq $0x33\npushq $1f\nlretq $8\n1:"); cf. PR8592 and commit r118903, which added LRETQ. I only added LRETIQ to match it. I don't quite understand how the Intel syntax parsing for ret instructions is working, despite r154468 allegedly fixing it. Aren't the explicitly sized 'retw', 'retd' and 'retq' supposed to work? I have at least made the 'lretq' work with (and indeed require) the 'q'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199106 91177308-0d34-0410-b5e6-96231b3b80d8		2014-01-13 14:05:59 +00:00
