The -frename-registers option was disabled because it exposed
bugs. You can look at the original discussion to find more details.
2004-04-20 Paolo Bonzini <bonzini@gnu.org>
Revert part of 2004-04-17 change that moved -frename-registers
to -O1. -frename-registers is buggy.
* toplev.c (flag_rename_registers): Initialize to 0.
* doc/invoke.texi (Optimize options): Move -frename-registers
to "Not triggered by any -O level" section. Adjust commentary
accordingly.
