Basic test case with exceptions.
Trunk revision: r304838
MIR input from -stop-before passfoo should be able to be parsed by
-start-before passfoo. This is failing today with exceptions involved.
StopBeforeStartAfterExceptions.ll (attached) is a really basic test case with
exceptions.
$ llc -mtriple=x86_64-- StopBeforeStartAfterExceptions.ll -stop-before
prologepilog -o /tmp/mir.mir
$ llc -mtriple=x86_64-- /tmp/mir.mir -start-before prologepilog -o -
error: /tmp/mir.mir:65:14: expected a machine operand
EH_LABEL <mcsymbol .Ltmp0>
This seems to be related to the FIXME in CodeGen/MIRParser/MIParser.cpp
