Hi, when reading the gcc/opts.c sources, I noticed that the docs don't mention -ftree-loop-distribute-patterns along the other switches enabled with -O3.
This documentation was missing since this option's introduction in SVN r162822 and should be backported to the 4.6, 4.7, 4.8 and 4.9 branches (if still alive). 2014-07-18 Horst Schirmeier <ho...@schirmeier.com> * doc/invoke.texi: -O3 enables -ftree-loop-distribute-patterns. diff --git a/gcc/doc/invoke.texi b/gcc/doc/invoke.texi index b5e8d98..b0a8eb8 100644 --- a/gcc/doc/invoke.texi +++ b/gcc/doc/invoke.texi @@ -7030,6 +7030,7 @@ Optimize yet more. @option{-O3} turns on all optimizations specified by @option{-O2} and also turns on the @option{-finline-functions}, @option{-funswitch-loops}, @option{-fpredictive-commoning}, @option{-fgcse-after-reload}, @option{-ftree-loop-vectorize}, +@option{-ftree-loop-distribute-patterns}, @option{-ftree-slp-vectorize}, @option{-fvect-cost-model}, @option{-ftree-partial-pre} and @option{-fipa-cp-clone} options. -- PGP-Key 0xD40E0E7A
