mold+gcc14 causes link failure for profiler gui #791

Closed HeliumAnt closed 1 month ago

HeliumAnt commented 1 month ago

The profiler GUI doesn't link with mold (master branch, Arch Linux, gcc-14.1.1). Which would be fine since it still works with other linkers, however due to the hardcoded override this is quite annoying.

This happens with gcc 13 or 14, when LTO is enabled.

With 813f4243 mold will only be used if clang is the compiler.
