Subject: PR82045: Avoid passing machine modes through "..."
Date: Fri, 01 Sep 2017 13:55:00 -0000
Message-ID: <87efrq1q2v.fsf@linaro.org>
User-Agent: Gnus/5.13 (Gnus v5.13) Emacs/25.2 (gnu/linux)
MIME-Version: 1.0

PR82045 is about a bootstrap failure on sparc-sun-solaris2.11.
The problem was that we were passing the new machine_mode wrapper
classes through "..."  to emit_library_call(_value), which then
read them back as ints instead.

The simplest fix seemed to be replace "..." with an array of
rtx_mode_ts, then provide wrappers for the common cases.  This
bulks out rtl.h a bit, but it does make things a bit more typesafe.

AFAICT this is the only place where we passed machine_modes this way.

Tested so far on aarch64-linux-gnu, powerpc64le-linux-gnu and
x86_64-linux-gnu.  Rainer also tested an earlier version on
sparc-sun-solaris2.11 (thanks).  Some multi-target testing is
still in progress.  OK to install if the remaining tests pass?
