Subject: [AArch64 array_mode 4/8] Remove EImode
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6ec0e5b9c323dbbdfafb49d2c946be8f43237214;p=gcc.git

[AArch64 array_mode 4/8] Remove EImode

	* config/aarch64/aarch64.c (aarch64_simd_attr_length_rglist): Update
	comment.
	* config/aarch64/aarch64-builtins.c (ei_UP): Remove.
	(aarch64_simd_intEI_type_node): Likewise.
	(aarch64_simd_builtin_std_type): Remove EImode case.
	(aarch64_init_simd_builtin_types): Don't create/add intEI_type_node.
	* config/aarch64/aarch64-modes.def: Remove EImode.
