Hello, I've gcc x86_64-pc-linux-gnu to riscv64-unknown-linux-gnu cross-compiler configured as: /repo/gcc-trunk//configure --enable-languages=c,c++ --enable-valgrind- annotations --disable-nls --enable-checking=yes,rtl,df,extra --with-cloog -- with-ppl --with-isl --with-sysroot=/usr/riscv64-unknown-linux-gnu --build=x 86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --target=riscv64-unknown-linux -gnu --with-ld=/usr/bin/riscv64-unknown-linux-gnu-ld --with-as=/usr/bin/ riscv64-unknown-linux-gnu-as --disable-multilib --disable-libstdcxx-pch -- prefix=/repo/gcc-trunk//binary-trunk-r11-767-20200601155732-gff7da2b5d62- checking-yes-rtl-df-extra-riscv64 Recently, probably since the libsanitizer master merge https://gcc.gnu.org/ pipermail/gcc-patches/2020-June/547010.html , I am failing to build the libsanitizer: libtool: compile: /repo/build-gcc-trunk-riscv64/./gcc/xgcc -shared-libgcc - B/repo/build-gcc-trunk-riscv64/./gcc -nostdinc++ -L/repo/build-gcc-trunk- riscv64/riscv64-unknown-linux-gnu/libstdc++-v3/src -L/repo/build-gcc-trunk- riscv64/riscv64-unknown-linux-gnu/libstdc++-v3/src/.libs -L/repo/build-gcc- trunk-riscv64/riscv64-unknown-linux-gnu/libstdc++-v3/libsupc++/.libs -B/ repo/gcc-trunk//binary-trunk-r11-962-20200605114410-g6c6931a353a-checking- yes-rtl-df-extra-riscv64/riscv64-unknown-linux-gnu/bin/ -B/repo/gcc-trunk// binary-trunk-r11-962-20200605114410-g6c6931a353a-checking-yes-rtl-df-extra- riscv64/riscv64-unknown-linux-gnu/lib/ -isystem /repo/gcc-trunk//binary- trunk-r11-962-20200605114410-g6c6931a353a-checking-yes-rtl-df-extra-riscv64/ riscv64-unknown-linux-gnu/include -isystem /repo/gcc-trunk//binary-trunk-r11 -962-20200605114410-g6c6931a353a-checking-yes-rtl-df-extra-riscv64/riscv64- unknown-linux-gnu/sys-include -D_GNU_SOURCE -D_DEBUG -D__STDC_CONSTANT_ MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -DHAVE_RPC_XDR_H=0 - DHAVE_TIRPC_RPC_XDR_H=0 -I. -I/repo/gcc-trunk/libsanitizer/sanitizer_common -I.. -I /repo/gcc-trunk/libsanitizer/include -I /repo/gcc-trunk/libsanitizer -isystem /repo/gcc-trunk/libsanitizer/include/system -Wall -W -Wno-unused- parameter -Wwrite-strings -pedantic -Wno-long-long -fPIC -fno-builtin -fno- exceptions -fno-rtti -fomit-frame-pointer -funwind-tables -fvisibility= hidden -Wno-variadic-macros -I../../libstdc++-v3/include -I../../libstdc++-v 3/include/riscv64-unknown-linux-gnu -I/repo/gcc-trunk/libsanitizer/../ libstdc++-v3/libsupc++ -std=gnu++11 -DSANITIZER_LIBBACKTRACE -DSANITIZER_CP_ DEMANGLE -I /repo/gcc-trunk/libsanitizer/../libbacktrace -I ../libbacktrace -I /repo/gcc-trunk/libsanitizer/../include -include /repo/gcc-trunk/ libsanitizer/libbacktrace/backtrace-rename.h -g -O2 -D_GNU_SOURCE -MT sanitizer_linux.lo -MD -MP -MF .deps/sanitizer_linux.Tpo -c /repo/gcc-trunk/ libsanitizer/sanitizer_common/sanitizer_linux.cpp -fPIC -DPIC -o .libs/ sanitizer_linux.o /repo/gcc-trunk/libsanitizer/sanitizer_common/sanitizer_linux.cpp:1880:12: warning: binary constants are a C++14 feature or GCC extension 1880 | case 0b10'010: // c.lwsp (rd != x0) | ^~~~ /repo/gcc-trunk/libsanitizer/sanitizer_common/sanitizer_linux.cpp:1880:16: warning: missing terminating ' character 1880 | case 0b10'010: // c.lwsp (rd != x0) | ^ /repo/gcc-trunk/libsanitizer/sanitizer_common/sanitizer_linux.cpp:1880:16: error: missing terminating ' character 1880 | case 0b10'010: // c.lwsp (rd != x0) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ It seems -std=gnu++11 should be replaced by -std=gnu++14 ; but since I couldn't find anyone else reporting this issue, maybe the problem is on my side?
