Can Gentoo's compiler be switched to another compiler to speed up installations?
I know there is a fix to make Gentoo use all cores (EMERGE_DEFAULT_OPTS and MAKEOPTS) and another fix to have a server compile the code (distcc). |

If you look at the downloads page, you have a choice of GCC or LLVM+clang as default compiler in the stage 3 image at least for amd64.
Whether changing compiler will speed up anything is another story.

They are options in make.conf file not "fixes".

The biggest "fix" is to compile on fast hardware. |

for important differences between gcc and clang, please see wiki:
https://wiki.gentoo.org/wiki/Clang
not understanding them may break your system. |
