Bug #: 51390
Summary: Builtin changes on November 29th, broke recip-5.c
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: meissner@gcc.gnu.org
ReportedBy: meissner@gcc.gnu.org
Host: powerpc64-linux power-linux
Target: powerpc64-linux
Build: powerpc64-linux
After my builtin changes went in on November 29th, 2011, the test
gcc.target/powerpc/recip-5.c started failing. This was due to a thinko on my
part where I used the wrong structure field to figure out the appropriate
attributes for the builtin function, and the recipdiv builtin function was not
listed as a const function with -ffast-math, which would allow the vectorizer
to vectorize the function.
