New Revision: 42259
URL: http://llvm.org/viewvc/llvm-project?rev=42259&view=rev
Log:
claim that "st" is from the 80-bit register file. This causes x87-using inline
asm to die with:
ScheduleDAG.cpp:269: failed assertion `false && "Couldn't find the register
class"'
instead of:
failed assertion `RegMap->getRegClass(VReg) == RC && "Register class of operand
and regclass of use don't agree!"'
yay.
