From 6ee2cc70024253d2670a4a317158b2a65251a1d1 Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Mon, 30 Sep 2019 16:19:59 +0000 Subject: Pass an ABI identifier to hard_regno_call_part_clobbered This patch replaces the rtx_insn argument to targetm.hard_regno_call_part_clobbered with an ABI identifier, since call insns are now just one possible way of getting an ABI handle. This in turn allows predefined_function_abi::initialize to do the right thing for non-default ABIs. The horrible ?: in need_for_call_save_p goes away in a later patch, with the series as a whole removing most direct calls to the hook in favour of function_abi operations. 2019-09-30 Richard Sandiford gcc/ * target.def (hard_regno_call_part_clobbered): Take an ABI identifier instead of an rtx_insn. * doc/tm.texi: Regenerate. * hooks.h (hook_bool_insn_uint_mode_false): Delete.
