Subject: [gdb/testsuite] Fix inter-cu refs in inlined_subroutine-inheritance.exp
X-Git-Tag: binutils-2_33~822
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=385b97d3ac9c5c57a610d2e5b358ed888008ae31;p=platform%2Fupstream%2Fbinutils.git

[gdb/testsuite] Fix inter-cu refs in inlined_subroutine-inheritance.exp

When running gdb.dwarf2/inlined_subroutine-inheritance.exp with board
cc-with-dwz, we run into:
...
dwz: inlined_subroutine-inheritance: Couldn't find DIE referenced by \
  DW_AT_abstract_origin
...

The problem is that the DW_AT_abstract_origin attributes refer to DIEs in
other CUs, while the references are encoded using the cu-relative encoding
DW_FORM_ref4.

Fix this by forcing the references to use DW_FORM_ref_addr.

Tested on x86_64-linux.

Tested with commit c24bdb023c "Introduce dwarf2_cu::get_builder" reverted,
and verified that the test-case fails in the same way before and after this
patch.
