Re: [Linaro-TCWG-CI] gcc-16-6301-gb3c167b61fd7: 4 regressions on arm

by Tomasz Kaminski

Hi, This should be resolved by following commit that I have just pushed: commit 5513935f48e50e97c854b746e758842c846a7740 Author: Tomasz Kamiński <tkaminsk(a)redhat.com> Date: Wed Jan 7 17:24:55 2026 +0100 libstdc++: Use tree-dump-gimple in variant constant init tests. Use of scan-assembler-dem for matching against debug symbols, turned out to not be portable, as they representation in assembly output differs between platforms: arm use 60 columns limit, emitting multiple rows, and some platforms may encode them using base64. We use tree-dump-gimple instead, that outputs a constructor name portably, allowing us to simply match for invocation of constructor for given type, as each variable has different type. To use scan-tree-dump(-not) we load scantree.exp file and it's dependency scandump.exp from gcc/testsuite/lib. libstdc++-v3/ChangeLog: * testsuite/20_util/variant/constinit.cc: Use scan-tree-dump for matching of constructor. * testsuite/20_util/variant/constinit_compat.cc: Likewise. * testsuite/lib/libstdc++.exp: Load scantree.exp and scandump.exp.
