"error: CPU you selected does not support x86-64 instruction set" says an x86-64 GCC with -march=native. Uh... wat?
-
@marcan42 with another valid x64 arch it works? seems that native is resolving to another arch that is not yours. I had that problem once.
.@skgsergio Apparently -march=native (on this Via Nano) is resolving to -march=core2 -mtune=i386. I don't even.

@marcan42 What I said :) I was about to tweet you can use "gcc -march=native -Q --help=target" to see it but u were faster xDThanks. Twitter will use this to make your timeline better. UndoUndo

@marcan42 Seems that Via is *still* not supported (yep, when I had that problem was in a via nano too): https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html … -
@skgsergio not supported/optimized != utterly misdetected though. march=core2 with mtune=i386 makes no sense, this used to work.

@marcan42 Via skimped a bit on the microcode implementation, so I wouldn't be surprised if this is to work around random crashes. -
@sangwhanmoon Not gonna work around much if nothing compiles with it. It's a GCC bug.
