From a7c81bc1fb43366ca1b4332d8a6042b648a84cdc Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Tue, 20 Aug 2019 08:52:17 +0000 Subject: Use function_arg_info for TARGET_ARG_PARTIAL_BYTES This patch adds the function_arg_info class and uses it for TARGET_ARG_PARTIAL_BYTES. The hook is passed the promoted mode instead of the original type mode. The arguments aren't mentioned in the documentation, which is why the target.def change is so small. The patch changes "true" to "arg.named" in: gcc_assert (!epiphany_pass_by_reference (cum, mode, type, /* named */ true)); but epiphany_pass_by_reference doesn't care about the named flag. 2019-08-20 Richard Sandiford gcc/ * target.def (arg_partial_bytes): Take a function_arg_info instead of a mode, type and named flag. * doc/tm.texi: Regenerate. * target.h (function_arg_info): Declare. * calls.h (function_arg_info): New class. * targhooks.h (hook_int_CUMULATIVE_ARGS_mode_tree_bool_0): Delete.
