--- Comment #2 from Hans-Peter Nilsson <hp at gcc dot gnu.org> --- This has started to fail for cris-elf too, just with different error messages. Not completely sure whether I should tag along in this PR or open a new one, but since the former is easiest... Last known working: r17-1455-g811cc466193d7e First known failing: r17-1813-gc2ea08d913db44 In g++.log (with cut-n-pasto line-terminations): spawn -ignore SIGHUP /gccobj/gcc/testsuite/g++/../../xg++ -B/gccobj/gcc/testsuite/g++/../../ /gccsrc/gcc/testsuite/g++.\ dg/modules/compile-std1.C -fdiagnostics-plain-output -nostdinc++ -I/gccobj/cris-elf/libstdc++-v3/include/cris-elf -I/gc\ cobj/cris-elf/libstdc++-v3/include -I/gccsrc/libstdc++-v3/libsupc++ -I/gccsrc/libstdc++-v3/include/backward -I/gccsrc/l\ ibstdc++-v3/testsuite/util -fmessage-length=0 -std=c++29 -pedantic-errors -Wno-long-long -fmodules --compile-std-module\ -g -O -flang-info-include-translate -S -isystem /gccobj/cris-elf/./newlib/targ-include -isystem /gccsrc/newlib/libc/in\ clude -o compile-std1.s cc1plus: fatal error: bits/std.cc: No such file or directory compilation terminated. cc1plus: fatal error: bits/std.compat.cc: No such file or directory compilation terminated. /gccsrc/gcc/testsuite/g++.dg/modules/compile-std1.C:10:10: note: include '/gccobj/cris-elf/libstdc++-v3/include/cris-el\ f/bits/stdc++.h' translated to import In module imported at /gccsrc/gcc/testsuite/g++.dg/modules/compile-std1.C:8:1: std: error: failed to read compiled module: No such file or directory std: note: compiled module file is 'gcm.cache/std.gcm' std: note: imports must be built before being imported std: fatal error: returning to the gate for a mechanical issue compilation terminated. compiler exited with status 1 PASS: g++.dg/modules/compile-std1.C -std=c++29 (test for warnings, line 10) FAIL: g++.dg/modules/compile-std1.C -std=c++29 (test for excess errors) Excess errors: cc1plus: fatal error: bits/std.cc: No such file or directory compilation terminated. cc1plus: fatal error: bits/std.compat.cc: No such file or directory compilation terminated. std: error: failed to read compiled module: No such file or directory std: fatal error: returning to the gate for a mechanical issue compilation terminated. The notes are expected, the errors are new.
