Subject: Always initialize FPContractable.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ddc57332cdc86ed2db28a3b3761b774944937191;p=clang

Always initialize FPContractable.

false is used as a baseline here, we may want to allow contraction in some of
the cases.  Found by valgrind.
