Unreadable for humans `sed` can be as short as this:
[busybox] sed '/#def/s-.[$#]- -gp;d'
or without "-fverbose-asm" (i.e. #comments after instruction) even like this
olecom@flower:/tmp/blinux$ busybox sed '/#def/s [$] p;d'
arch/x86/kernel/asm-offsets.s
+ busybox sed '/#def/s [$] p;d' arch/x86/kernel/asm-offsets.s
#define tsk_state 0 /*offsetof(struct task_struct, state)*/
#define tsk_flags 20 /*offsetof(struct task_struct, flags)*/
#define tsk_pid 328 /*offsetof(struct task_struct, pid)*/
olecom@flower:/tmp/blinux$
The only thing to change is (unreadable) #define in asm-offsets.c:
#define DEFINE(sym, val) \
asm volatile("\n#define " #sym " %0 /*" #val "*/": : "i" (val))
(BLANK also, but it's a phony load)
