- Subject: [PATCH] Ignore properly -mdirect-move (PR target/87164).
Hi.
Option mdirect-move should be Deprecated, that means option value is ignored
and user can't influence rs6000_isa_flags.
Patch can bootstrap on ppc64le-redhat-linux (gcc110 and gcc112) and survives regression tests.
Ready to be installed?
Martin
