Re: [Linaro-TCWG-CI] gcc-16-5627-g4e7213aa081f: 1 regression on master-thumb_m55_hard_eabi

by Tomasz Kaminski

Hi, I am unable to reproduce the issue, and cannot access the included log files to check the failure. Could you please share the revelant part of log, at least from time/hash.cc?

Unfortunately, the code this test run of yours generates doesn't match the new pattern either.

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.

There seem to be two general issues: first, that some of the <stdio.h> functions that <print> relies on aren't declared: > /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-sta\ > ge2/arm-eabi/libstdc++-v3/include/print: In member function 'virtual void std::__format::_File_sink::_M_o\ > verflow()': > /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-sta\ > ge2/arm-eabi/libstdc++-v3/include/print:197:20: error: '::fwrite_unlocked' has not been declared; did you\ > mean '_fwrite_unlocked_r'? > /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-sta\ > ge2/arm-eabi/libstdc++-v3/include/print: In constructor 'std::__format::_File_sink::_File_sink(FILE*, boo\ > l)': > /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-sta\ > ge2/arm-eabi/libstdc++-v3/include/print:212:9: error: '::flockfile' has not been declared; did you mean '\ > _flockfile'? > /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-sta\ > ge2/arm-eabi/libstdc++-v3/include/print: In destructor 'std::__format::_File_sink::~_File_sink()': > /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-sta\ > ge2/arm-eabi/libstdc++-v3/include/print:218:11: error: '::putc_unlocked' has not been declared; did you m\ > ean '_putc_unlocked_r'? > /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-sta\ > ge2/arm-eabi/libstdc++-v3/include/print:219:9: error: '::funlockfile' has not been declared; did you mean\ > '_funlockfile'? It seems that newlib doesn't declare these functions under -std=c++26, only -std=gnu++26. I don't know what the right approach to this is. and then a bunch of "not declared" exports, such as > /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-sta\ > ge2/arm-eabi/libstdc++-v3/include/bits/std.cc:1002:14: error: 'condition_variable' has not been declared \ > in 'std' This looks like just needing to add more #if to std.cc, as below. OK for trunk? Incidentally, is it expected that arm-eabi doesn't support gthread? Jason
