Bug ID: 17988
Summary: batch mode wrong symbols in relocatable files with
debug link
Product: gdb
Version: 7.8
Status: NEW
Severity: normal
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org
Reporter: msebor at redhat dot com
When invoked on a relocatable object such as a kernel module with separate
debug info pointed to via a .gun_dbuglink section but linked without the
--build-id option, GDB reads in the debug symbols from the linked debug file
but doesn't seem to retain them. This works as expected for shared executables
or when the relocatable file is linked with --build-id.
$ (set -x; for strip in true eu-strip; do echo "int foo (char a, long b) {
return a + b; }" | gcc -c -g -o a.o -xc - && ld -r -o a a.o && $strip -f a.dbg
a && gdb -batch -ex "info functions" -q a; done)
+ for strip in true eu-strip
+ echo 'int foo (char a, long b) { return a + b; }'
+ gcc -c -g -o a.o -xc -
+ ld -r -o a a.o
+ true -f a.dbg a
+ gdb -batch -ex 'info functions' -q a
All defined functions:
File <stdin>:
int foo(char, long);
+ for strip in true eu-strip
+ echo 'int foo (char a, long b) { return a + b; }'
+ gcc -c -g -o a.o -xc -
+ ld -r -o a a.o
+ eu-strip -f a.dbg a
