From: Tom de Vries Date: Wed, 12 Oct 2022 15:02:15 +0000 (+0200) Subject: [gdb/testsuite] Fix ctf test-cases on openSUSE Tumbleweed X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=908a926ec4ecd48571aafb560d97b927b6f94b5e;p=binutils-gdb.git [gdb/testsuite] Fix ctf test-cases on openSUSE Tumbleweed When running test-case gdb.base/ctf-constvars.exp on openSUSE Tumbleweed (with system gcc version 12, providing gcc -gctf support, enabling the ctf test-cases in the gdb testsuite), I run into: ... (gdb) print vox^M 'vox' has unknown type; cast it to its declared type^M (gdb) FAIL: gdb.base/ctf-constvars.exp: print vox ... There are two causes for this: - the linker flags are missing --ctf-variables, so the information for variable vox is missing (reported in PR29468), and - the executable contains some dwarf2 due to some linked-in glibc objects, so the ctf info is ignored (reported in PR29160). By using: - -Wl,--ctf-variable, - -Wl,--strip-debug, and we can make the test-case and some similar test-cases pass. Tested on x86_64-linux.
