CheckIPOSupported does not check if exe runs
Hello. CheckIPOSupported
method today is too weak. Please install latest mingw-w64-x86_64-gcc
version 10.2.0-6 on windows. This version has broken LTO support (executable segfaults), but CheckIPOSupported
succeeded.
Please improve CheckIPOSupported
by running created executable (if current platform can run executable).
For example please refer the following files: CheckIPO.cmake and IPO.
Please refer the following issue on mingw github.
