--- Comment #5 from Joel Rosdahl <joel at rosdahl dot net> --- Created attachment 13656 --> https://sourceware.org/bugzilla/attachment.cgi?id=13656&action=edit gas: Apply debug prefix map to DWARF-5 PWD entry in directory table (In reply to Nick Clifton from comment #4) > OK, well I cannot reproduce that behaviour Oh, that's peculiar. Here's the reproduction recipe in self-contained script form: #!/bin/sh tmpdir=$(mktemp -d) trap "rm -rf ${tmpdir}" EXIT cd $tmpdir echo 'int x;' >test.c /usr/bin/gcc -g -fdebug-prefix-map="${tmpdir}=/example" -c test.c if grep -q "${tmpdir}" test.o; then echo "FAIL: PWD found in object file" else echo "OK" fi With binutils-2.35.1-41.fc34.x86_64.rpm: % ./repro OK With binutils-2.35.2-5.fc34.x86_64.rpm: % ./repro FAIL: PWD found in object file > Do you have a suggested patch to fix the problem ? I didn't, but after having spent some time in the GAS code I now have. See attachment. One thing that I'm not 100% sure of is if it's OK to rely on $COLLECT_GCC_OPTIONS in GAS. I haven't studied how that variable is used by other parts of the toolchain; I only noted that it's available and contains the information we need. -- You are receiving this mail because: You are on the CC list for the bug.
