Issue 204974: dump_syms fails on objects with -ffunction-sections (hardcodes ".text" section name assumption)
1 person starred this issue and may be notified of changes. Back to list
 
Project Member Reported by vapier@chromium.org, Oct 20, 2011 
dump_syms assumes there is only section of code and it is named ".text".  violate that assumption, and dump_syms gets angry.

$ gcc -c -x c - -o test.o -m32 -ffunction-sections <<<"main(){}"
$ dump_syms test.o
/home/vapier/test.o: unable to generate file identifier
Failed to write symbol file.

To note, I needed to also pass "-ggdb2" to gcc to get dump_syms to work without "-ffunction-sections".

TEST=`emerge-x86-alex chromeos-kernel` no longer throws errors during stripping
TEST=`emerge-x86-alex chromeos-kernel` has split debug files for kernel modules
TEST=`emerge-x86-alex python` does not have debug file for python.o, and lacks debug sections
TEST=`emerge-x86-alex chromeos-base/autotest-deps-libaio` does not have debug file for raw_syscall.os, and lacks debug sections
TEST=`cros_generate_breakpad_symbols --board x86-alex` still works
