| |
kernel/sched.c gets compiled with -fno-omit-frame-pointer, and this was already done in kernel 1.0 (sic).
Later, it has been modified to be this way only on some architectures.
It might not be an earthshaking amount, but removing it saves some bytes, and there's no visible breakage when running the modified kernel on i386.
$ ls -la kernel/sched.o* -rw-rw-r-- 1 bunk bunk 25600 2007-08-19 16:10 kernel/sched.o -rw-rw-r-- 1 bunk bunk 26084 2007-08-19 16:03 kernel/sched.o.old $ size kernel/sched.o* text data bss dec hex filename 11835 184 2000 14019 36c3 kernel/sched.o 12321 184 2000 14505 38a9 kernel/sched.o.old $
Is the -fno-omit-frame-pointer still required for some reason, or is this a relict that could be removed?
