Bug ID: 104859 Summary: [12 regression] liibg++ fails during bootstrap Product: gcc Version: 12.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libgcc Assignee: unassigned at gcc dot gnu.org Reporter: seurer at gcc dot gnu.org Target Milestone: --- Seen with g:bded0d549fdfdc1328b2c0189dc5f8593b4cbe42 r12-7566-gbded0d549fdfdc but that is probably not the source. I am still bisecting this but as it is breaking the build I thought I should open it right away. libtool: compile: /home/seurer/gcc/git/build/gcc-test/./gcc/xgcc -shared-libgcc -B/home/seurer/gcc/git/build/gcc-test/./gcc -nostdinc++ -L/home/seurer/gcc/git/build/gcc-test/powerpc64-unknown-linux-gnu/32/libstdc++-v3/src -L/home/seurer/gcc/git/build/gcc-test/powerpc64-unknown-linux-gnu/32/libstdc++-v3/src/.libs -L/home/seurer/gcc/git/build/gcc-test/powerpc64-unknown-linux-gnu/32/libstdc++-v3/libsupc++/.libs -B/home/seurer/gcc/git/install/gcc-test/powerpc64-unknown-linux-gnu/bin/ -B/home/seurer/gcc/git/install/gcc-test/powerpc64-unknown-linux-gnu/lib/ -isystem /home/seurer/gcc/git/install/gcc-test/powerpc64-unknown-linux-gnu/include -isystem /home/seurer/gcc/git/install/gcc-test/powerpc64-unknown-linux-gnu/sys-include -m32 -I/home/seurer/gcc/git/gcc-test/libstdc++-v3/../libgcc -I/home/seurer/gcc/git/build/gcc-test/powerpc64-unknown-linux-gnu/32/libstdc++-v3/include/powerpc64-unknown-linux-gnu -I/home/seurer/gcc/git/build/gcc-test/powerpc64-unknown-linux-gnu/32/libstdc++-v3/include -I/home/seurer/gcc/git/gcc-test/libstdc++-v3/libsupc++ -std=gnu++17 -nostdinc++ -D_GLIBCXX_SHARED -fno-implicit-templates -Wall -Wextra -Wwrite-strings -Wcast-qual -Wabi=2 -fdiagnostics-show-location=once -ffunction-sections -fdata-sections -frandom-seed=floating_to_chars.lo -fimplicit-templates -g -O2 -D_GNU_SOURCE -m32 -c /home/seurer/gcc/git/gcc-test/libstdc++-v3/src/c++17/floating_to_chars.cc -fPIC -DPIC -D_GLIBCXX_SHARED -o floating_to_chars.o /home/seurer/gcc/git/gcc-test/libstdc++-v3/src/c++17/floating_to_chars.cc: In instantiation of 'std::to_chars_result std::__floating_to_chars_hex(char*, char*, T, optional<int>) [with T = long double]': /home/seurer/gcc/git/gcc-test/libstdc++-v3/src/c++17/floating_to_chars.cc:926:37: required from 'std::to_chars_result std::__floating_to_chars_shortest(char*, char*, T, chars_format) [with T = long double]' /home/seurer/gcc/git/gcc-test/libstdc++-v3/src/c++17/floating_to_chars.cc:1612:40: required from here /home/seurer/gcc/git/gcc-test/libstdc++-v3/src/c++17/floating_to_chars.cc:804:52: error: cannot convert '{anonymous}::uint128_t' to 'const unsigned int' in initialization 804 | const unsigned nibble = effective_mantissa >> rounded_mantissa_bits; | ~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~ | | | {anonymous}::uint128_t /home/seurer/gcc/git/gcc-test/libstdc++-v3/src/c++17/floating_to_chars.cc:856:56: error: cannot convert '{anonymous}::uint128_t' to 'const unsigned int' in initialization 856 | const unsigned nibble = effective_mantissa >> nibble_offset; | ~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~ | | | {anonymous}::uint128_t make[9]: *** [floating_to_chars.lo] Error 1
