Subject: Relax this check to silently swallow FE_INEXACT, following directions
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e3c65d1ede77c13c4dd0e07c5c908098466a14e0;p=oota-llvm.git

Relax this check to silently swallow FE_INEXACT, following directions
from rdar://8452472. This unbreaks gcc.dg/builtins-17.c.
