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 Which mentions optimizatoin flags twice and the repeated mention is out of date, since we enable this option at -O2 as well.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.
