Hi.
No one back end does not use PREFERRED_OUTPUT_RELOAD_CLASS macro now, this
patch remove it. The TARGET_PREFERRED_RELOAD_CLASS target hook should be use
instead.
The patch has been bootstrapped on and regression tested on
x86_64-unknown-linux-gnu for c and c++.
This patch is pre-approved and should be committed within a week if no
objections.
* doc/tm.texi.in (PREFERRED_OUTPUT_RELOAD_CLASS): Remove.
* doc/tm.texi: Regenerate.
* targhooks.c (default_preferred_output_reload_class): Don't use
PREFERRED_OUTPUT_RELOAD_CLASS macro.
* system.h (PREFERRED_OUTPUT_RELOAD_CLASS): Poison.
