Subject: now that GetSSETypeAtOffset handles passing SSE class values as
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1b32ae9537186c021409bebeaa308db886ed98a2;p=clang

now that GetSSETypeAtOffset handles passing SSE class values as
float, the special case hack in getCoerceResult can go away.
