Almost the entire polyhedron benchmark suite fails with -Ofast -march=bdver3.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61360 --- Comment #5 from Zdenek Sojka zsojka at seznam dot cz --- If anyone is interested in what architecutres are affected without looking at the source code, there are rough statistics of ICEs encountered since it first appeared: ICEs count | switch 21 -march=bdver3 160 -mtune=amdfam10 134 -mtune=barcelona 153 -mtune=bdver1 129 -mtune=bdver2 176 -mtune=bdver3 145 -mtune=bdver4 The reason for so low -march= count is that I am no longer using the -march= switch. Other architectures are likely not affected.

This is due to the use of the enabled attribute in:

[(set (match_operand:MODEF 0 register_operand =f,x,x)

(cond [(eq_attr alternative 0)

(eq_attr alternative 1)
/* ??? For sched1 we need constrain_operands to be able to

])
enabled was really only supposed to be used to enable or disable
alternatives according to the current subtarget, rather than enable
or disable them based on the current stage in the pass pipeline
or on whether the function is being compiled for size or speed.
I have an idea for handling the size/speed thing, but we need
to fix the ??? as well.
