- Subject: [PATCH,committed,toplevel] Sync configure.ac with gcc@165133
FYI:
Committed the attached to keep top-level in sync with GCC after applying it
over there first.
ChangeLog:
* configure.ac (build_lto_plugin): New shell variable.
(--enable-lto): Turn on by default for all non-ELF platforms that
have had LTO support added so far. Set build_lto_plugin appropriately
for both ELF and non-ELF.
(configdirs): Add lto-plugin or not based on build_lto_plugin.
* configure: Regenerate.
cheers,
DaveK
