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

Re: [Linaro-TCWG-CI] gdb-17-branchpoint-981-gcc1fc6af415: 77 regressions on arm

by Jan Vraný

Hi, unfortunately I do not have arm system at hand. I tried to build this commit on QEMU (qemu-system-arm) running Debian (armhf architecture) and I cannot reproduce any of the regressions. I'd appreciate some information on how to build and run suitable armv8l system on QEMU (or, if that's easier, on Odroid-N2) - I could not find much. Thanks!
