head -r309179 clang 3.9.0 for TARGET_ARCH=powerpc64 with devel/powerpc64-binutils used: WITH_LIB32= related assembler source rejected. . .

Mon Nov 28 03:01:41 UTC 2016

[Note: ld from WITH_BINTOOLS_BOOTSTRAP= for buildworld fails and stops
buildworld. This explains the use of devel/powerpc64-binutils below.]

Using clang 3.9.0 for TARGET_ARCH=powerpc64 with
devel/powerpc64-binutils (of an appropriate vintage) apparently
requires r1 instead of 1 for a register name --and so on.

It turns out that trying to use WITH_LIB32= for TARGET_ARCH=powerpc64
with devel/powerpc64-binutils runs into assembler source files that
are rejected for this reason.

There are also complaints about invalid mnemonics (mflr and mr).

The error reports:
(Other files may well have the same sorts of problems.)
