Log message:
2004-04-17 Paolo Bonzini <bonzini@gnu.org>
* opts.c (decode_options): Do not enable flag_rename_registers
and flag_web at -O3.
* toplev.c (flag_rename_registers): Initialize
flag_rename_registers and flag_web to
AUTODETECT_FLAG_VAR_TRACKING.
(default_debug_hooks): New global.
(process_options): Initialize default_debug_hooks. Warn if
-fvar-tracking specified but not supported by the current
debug format. Do not run var tracking at -O0 or if not
supported by the current debug format, even if
-fvar-tracking was given. If -fno-rename-registers
is not specified, always run register renaming if var
tracking is supported by the default debugging information
format for the target, and we are at -O1 or higher; similarly
for -fweb, but only at -O2 or higher.
* doc/invoke.texi (Optimize Options): Document this.
