The current --param flag in clang doesn’t match gcc’s at all. In GCC this flag is documented as --param NAME=VALUE where NAME is something like “struct-reorg-cold-struct-ratio”. What clang seems to do is under a big FIXME, pass whatever is given to --param to all the subprocesses it executes.
That’s not okay.
Why does it work this way? Would anyone object to me removing the flag entirely, or making the driver accept --param then ignore its contents?
