Hi,
we have:
-ftree-loop-distribute-patterns
Perform loop distribution of patterns that can be code generated
with calls to a library. This flag is enabled by default at -O2 and higher,
and by -fprofile-use and -fauto-profile.
This pass distributes the initialization loops and generates a call
to memset zero. For example, the loop
...
and the initialization loop is transformed into a call to memset
zero. This flag is enabled by default at -O3. It is also enabled by
-fprofile-use and -fauto-profile.
Which mentions optimizatoin flags twice and the repeated mention is out of
date, since we enable this option at -O2 as well.
Regtested x86_64-linux, plan to commit it shortly as obvious.
gcc/ChangeLog:
* doc/invoke.texi (-ftree-loop-distribute-patterns): Remove duplicated
sentence about optimization flags implying this.
