[llvm-commits] [llvm] r73989 - /llvm/trunk/lib/Target/X86/X86InstrMMX.td

[Bill Wendling]

Author: void

New Revision: 73989

URL: http://llvm.org/viewvc/llvm-project?rev=73989&view=rev
Log:
"The MMX_MASKMOVQ and MMX_MASKMOVQ64 instructions are labeled as MRMDestMem
instructions, which implies that there is an explicit memory operand.  There is
(however) no explicit memory operand; although this is a store, the only memory
operand is implicit, indicated by DS:EDI.  This causes the table-generation code
for the disassembler to report an error."

Patch by Sean Callanan!
