Description dawe 2007-05-14 09:49:29 UTC

Hi all, I'm trying to compile gcc 4.1.1-r3 on alpha, it is considered stable, but evidently it doesn't compile (at least on my system). I'm attaching a lot of material.
I've tried to modify -march flag to ev67 to ev6 (sometimes works), but without any benefit.

Reproducible: Always

Steps to Reproduce:
1. emerge -aO gcc
Actual Results:

does it fail in the same place every time with the same error message ?

Yes. I've tried to manually compile gcc with portage configuration layout (i.e. passing to configure the same args portage does) and it works as I add -Wa,-mev6 CFLAG. I've noticed that this flag is not included in ALLOWED_FLAGS while emerging gcc.
I've done a working gcc 4.1.1 and then used it to emerge gcc-4.1.1, it works. What is strange is that the -Wa,-mev6 flag is not needed by gcc 4.1.1 to compile gcc 4.1.1 (in fact portage still excludes it from ALLOWED_FLAGS)

just built gcc-4.1.2 on an alphaev68 with -mcpu=ev67 and CHOST=alphaev68

-Wa belongs in ASFLAGS, not CFLAGS

that said, there is no reason at all you should be setting that yourself
