Subject: [PATCH] scripts/decode_stacktrace.sh: prefix addr2line with $CROSS_COMPILE
Date: Mon, 27 May 2019 10:34:25 +0200
Message-ID: <20190527083425.3763-1-manut@linutronix.de> (raw)

At least for ARM64 kernels compiled with the crosstoolchain from
Debian/stretch or with the toolchain from kernel.org the line number is not
decoded correctly by 'decode_stacktrace.sh':

$ echo "[  136.513051]  f1+0x0/0xc [kcrash]" | \
  CROSS_COMPILE=/opt/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- \
 ./scripts/decode_stacktrace.sh /scratch/linux-arm64/vmlinux \
                                /scratch/linux-arm64 \
                                /nfs/debian/lib/modules/4.20.0-devel
[  136.513051] f1 (/linux/drivers/staging/kcrash/kcrash.c:68) kcrash

If addr2line from the toolchain is used the decoded line number is correct:

[  136.513051] f1 (/linux/drivers/staging/kcrash/kcrash.c:57) kcrash
