Subject: [Bug fortran/17030] New: gfortran does not optimize ABS of complex that well
X-Bugzilla-Reason: CC

List-Id: <gcc-bugs.sourceware.org>

gfortran just calls cabsf even with -ffast-math which changes cabsf into sqrt (r*r+i*i) which improves 
code generation a huge amount and should improve facerec a huge amount too.
