Subject: Don't perform integer promotions on the operand to a cast; this
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=199ea95fd5ef9a089dbf7b2ade018d4444a65177;p=clang

Don't perform integer promotions on the operand to a cast; this
simplifies the AST, and can matter in some rare cases involving
casts to vector types. Patch by Enea Zaffanella.
