Description Justin Hibbits freebsd_committer freebsd_triage 2019-02-01 15:33:43 UTC 
It seems the build of gcc* ports doesn't like the binutils update to 2.31, it now complains in the middle of the build (about 4 hours in) with a link-time build mismatch (some files built with double-precision floating point, other files with single-precision).  I think this is due to a quirk in the way gcc is built.

Someone did point out that the "--with-cpu=8540" is technically incorrect anyway, since we don't even support that platform in the first place.  The oldest platform we support for powerpcspe is the 8548. So changing

CONFIGURE_ARGS+= --with-cpu=8540....

to

CONFIGURE_ARGS+= --with-cpu=8548....

fixes the build, and everything is happy.

This may allow us to remove some CFLAGS, but I'm not concerned about that for now, and will adjust the flags in the system makefiles when I do get around to testing more.

I'll make this change across all relevant ports over the next days;
thanks for the report.

(In the course of this I noticed an obsolete trace of powerpcspe in
lang/gcc9-devel which I'll remove as well since that codebase simply
does not have support anymore at all.)

New revision: 492024
URL: https://svnweb.freebsd.org/changeset/ports/492024

Log:
  On powerpcspe configure GCC --with-cpu=8548 instead of --with-cpu=8540,
  which caused the build to fail after the update to binutils 2.31 and was
  factually incorrect anyways (the oldest we support being 8548). [1]

  On the way update to the 20180201 snapshot of GCC 8.2.1.

Comment 4 Gerald Pfeifer freebsd_committer freebsd_triage 2019-02-04 09:47:43 UTC 
I think I caught everything, i.e., all regular lang/gcc* ports where
powerpcspe is listed as a platform.

Thanks for the report and suggested fix, Justin, and let me know if
there's anything more.
