Subject: What does unwcheck.pl do?
Date: Mon, 25 Oct 2004 17:21:50 +0000 [thread overview]
Message-ID: <523c02d87l.fsf@topspin.com> (raw)
When I build an ia64 kernel, I get a warning about ia64_monarch_init_handler:
$ make O=../kbuild-ia64
Using /data/home/roland/Src/linux-2.6.9 as source for kernel
CHK include/linux/version.h
make[2]: rch/ia64/kernel/asm-offsets.s' is up to date.
CHK include/asm-ia64/offsets.h
CHK include/linux/compile.h
ERROR: ia64_monarch_init_handler: 186 slots, total region length = 0
1 error detected in 9381 functions.
make[1]: [unwcheck] Error 1 (ignored)
Building modules, stage 2.
MODPOST
This is with gcc 3.4.1/binutils 2.15 (built with Dan Kegel's crosstool):
$ ${CROSS_COMPILE}gcc --version
ia64-unknown-linux-gnu-gcc (GCC) 3.4.1

I can see the ERROR: comes from unwcheck.pl but I have no idea what it
is checking (something to do with unwind info?) let alone how to fix
the problem.
Is this benign or is there something to be fixed?
Thanks,
Roland
