There are many regressions on mips64el between 265378 and 265420. r265378 testresults: https://gcc.gnu.org/ml/gcc-testresults/2018-10/msg02935.html r265420 testresults: https://gcc.gnu.org/ml/gcc-testresults/2018-10/msg03065.html I bisected at least one to this commit on mips64el: FAIL: gcc.c-torture/execute/builtins/memcpy-chk.c compilation, -O1 (internal compiler error) FAIL: gcc.c-torture/execute/builtins/memcpy-chk.c compilation, -O2 (internal compiler error) FAIL: gcc.c-torture/execute/builtins/memcpy-chk.c compilation, -O2 -flto -fno-use-linker-plugin -flto-partition=none (internal compiler error) FAIL: gcc.c-torture/execute/builtins/memcpy-chk.c compilation, -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects (internal compiler error) FAIL: gcc.c-torture/execute/builtins/memcpy-chk.c compilation, -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions (internal compiler error) FAIL: gcc.c-torture/execute/builtins/memcpy-chk.c compilation, -O3 -g (internal compiler error) FAIL: gcc.c-torture/execute/builtins/memcpy-chk.c compilation, -Og -g (internal compiler error) FAIL: gcc.c-torture/execute/builtins/memcpy-chk.c compilation, -Os (internal compiler error) I filed a bug at https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87720.
