[PATCH] parisc: fix the exit status of arch/parisc/nm

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Parisc overrides 'nm' with a shell script. I was hit by a false-positive
error of $(NM) because this script returns the exit code of grep instead
of ${CROSS_COMPILE}nm. (grep exits with 1 if no lines were selected)

I tried to fix it, but in the code review, Helge suggested to remove it
entirely. [1]

This script was added in 2003. [2]

Presumably, it was a workaround for old toolchains (but even the parisc
maintainer does not know the detail any more).

Hopefully recent tools should work fine.

I want to apply this to kbuild tree with Helge's Ack
