- Subject: [M32R] Hookize GO_IF_MODE_DEPENDENT_ADDRESS
Hi.
This patch removes obsolete GO_IF_MODE_DEPENDENT_ADDRESS macro from the
M32R back end in the GCC and introduces equivalent
TARGET_MODE_DEPENDENT_ADDRESS_P target hook.
Regression tested on m32r-unknown-elf.
OK to install?
* config/m32r/m32r.c (m32r_mode_dependent_address_p): New functions.
(TARGET_MODE_DEPENDENT_ADDRESS_P): Define.
* config/m32r/m32r.h: (GO_IF_MODE_DEPENDENT_ADDRESS): Remove.
