How long does gcc take to build

I am suspicious that the compiler build itself was done with at least some optimizations turned off. In the q2 7. In the q4 8. By comparison, in the Arch build of arm-none-eabi-gcc for gcc8, which is 8. Perhaps the builder turned off optimization for debugging and forgot to turn it back on? Or was there some other reason? I haven't yet tried to build from source, or examine the source Makefiles.

Terry, Thanks for reporting and analyzing the issue. It is a confirmed bug in the build script and has just been fixed, in a way slightly different to what you shared. The updated script and binary package will be included in the next release.

Is it just for verification? If so, it seems pretty wasteful. I mean the whole compiler is written in C right, so why not just do everything in one pass?
