Description
I build the master code with `sh build.sh --extra-cmake-defines='{"CMAKE_PREFIX_PATH":"/usr/include/openssl11"}'` on centos 7.9 with gcc 11.
It failed with error `/root/workspace/folly/folly/lang/Hint-inl.h:109:3: error: impossible constraint in 'asm'`
Contributor guide
Research direction
Reproduce the reported build with `sh build.sh --extra-cmake-defines='{"CMAKE_PREFIX_PATH":"/usr/include/openssl11"}'` on CentOS 7.9 with GCC 11. Start at `folly/lang/Hint-inl.h:109` and investigate the reported impossible asm constraint; done means the build no longer fails there.
