Bug ID: 94249 Summary: [10 regression] Many -flto -fuse-linker-plugin tests FAIL: could not add symbols Product: gcc Version: 10.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: lto Assignee: unassigned at gcc dot gnu.org Reporter: ro at gcc dot gnu.org CC: marxin at gcc dot gnu.org Target Milestone: --- Host: sparc-sun-solaris2.11 Target: sparc-sun-solaris2.11 Build: sparc-sun-solaris2.11 Between 20200313 (fd8679974b2ded884ffd7d912efef7fe13e4ff4f) and 20200320 (719c864225e28c33a0737a331a772781ce8e6591), many LTO tests began to FAIL on Solaris/SPARC with gld 2.34, e.g. +FAIL: c-c++-common/asan/alloca_instruments_all_paddings.c -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects (test for excess errors) +UNRESOLVED: c-c++-common/asan/alloca_instruments_all_paddings.c -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects compilation failed to produce executable Excess errors: /vol/gcc/bin/gld-2.34: error: could not add symbols For some reason, this still works ok on Solaris/x86, though.
