Summary: fix type punning issue in bsaylor/svf~
Initial Comment: bsaylor/svf~.c uses a type punning method to avoid / eliminate subnormal numbers. When compiled with -ftree-vectorize, the object doesn't give signal output. Compiler warnings:
svf~.c: In function 'run_svf': svf~.c:60: warning: dereferencing type-punned pointer will break strict-aliasing rules svf~.c:61: warning: dereferencing type-punned pointer will break strict-aliasing rules ... cc1: warning: -ftree-vectorize enables strict aliasing. -fno-strict-aliasing is ignored when Auto Vectorization is used.
File bsaylor_svf~-type-punning-fix.patch fixes the issue by using PD_BIGORSMALL() function instead.
