FWIW, this last build issue is *not* fixed by this patch. This last
build failure is on mesa3d, with:
main/get.c: In function '_mesa_GetBooleani_v':
main/get.c:2320:1: error: insn does not satisfy its constraints:
}
^
(insn 79 72 80 7 (set (reg/f:SI 147 virtual-stack-vars)
(reg:SI 2 r2)) main/get.c:2315 3 {*movsi_insn}
(nil))
main/get.c:2320:1: internal compiler error: in extract_constrain_insn, at recog.c:2190
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugs.buildroot.net/> for instructions.
And the build result
http://autobuild.buildroot.net/results/5cc/5ccb47e2af780982d71d924ef30008f16573ad73//build-end.log
is the *exact* same failure, but at commit
https://git.buildroot.net/buildroot/commit/?id=2567f6f2f34a1ecfc25604bf8bf93b8bc065fc63,
which is *after* I committed and pushed your ARC fix (and the
configuration was using the internal toolchain backend, so the
toolchain was built from scratch).
Best regards,
Thomas
