- Subject: [SCORE] Hookize PREFERRED_RELOAD_CLASS
Hi.
This patch removes obsolete PREFERRED_RELOAD_CLASS macro from the SCORE
back end in the GCC and introduces equivalent TARGET_PREFERRED_RELOAD_CLASS
target hook.
Untested.
OK to install?
* config/score/score.h (PREFERRED_RELOAD_CLASS): Remove.
* config/score/score-protos.h (score_preferred_reload_class): Remove.
* config/score/score.c (TARGET_PREFERRED_RELOAD_CLASS: Define.
(score_preferred_reload_class): Make static. Change return and
'rclass' argument type to reg_class_t.
