[committed,gdb/testsuite] Fix gdb.dwarf2/macro-source-path.exp with -m32
Commit Message
Hi,
With test-case gdb.dwarf2/macro-source-path.exp and target board unix/-m32, I
run into:
...
as: macro-source-path-gcc11-ld238-dw5-filename-641.o: \
unsupported relocation type: 0x1^M
...
The problem is that we have 64-bit dwarf so the debug_line offset in the
.debug_macro section is an 8-byte entity, emitted using ".8byte":
...
.section .debug_macro
.Lcu_macros4:
.2byte 5 /* version */
.byte 3 /* flags */
.8byte .LLlines3 /* debug_line offset */
...
but the linker doesn't support 8-byte relocation types on a 32-bit architecture.
This is similar to what was fixed in commit a5ac8e7fa3b
("[gdb/testsuite] Fix 64-bit dwarf test-cases with -m32") for for instance
.debug_abbrev.
Fix this in the same way, by using _op_offset to emit the debug_line offset.
Tested on x86_64-linux with native and target board unix/-m32.
Committed to trunk.
Thanks,
- Tom
