Commit Message

Richard Earnshaw Jan. 20, 2022, 11:27 a.m. UTC 
A couple of patterns in the crypto support code were hard-coding the
mode rather than using the iterators.  While not incorrect, it was
slightly confusing, so adapt those patterns to the style of the rest
of the file.

Also fix some white space issues.

gcc/ChangeLog:

	* config/arm/crypto.md (crypto_<CYRPTO_AES:crypto_pattern>): Use
	<crypto_mode> rather than hard-coding the mode.
	(crypto_<CRYPTO_AESMC:crypto_pattern>): Fix white space.
	(crypto_<CRYPTO_AES:crypto_pattern>): Likewise.
	(*aarch32_crypto_aese_fused): Likewise.
	(*aarch32_crypto_aesd_fused): Likewise.
	(crypto_<CRYPTO_BINARY:crypto_pattern>): Likewise.
	(crypto_<CRYPTO_TERNARY:crypto_pattern>): Likewise.
	(crypto_sha1h_lb): Likewise.
	(crypto_vmullp64): Likewise.
	(crypto_<CRYPTO_SELECTING:crypto_pattern>): Likewise.
	(crypto_<CRYPTO_SELECTING:crypto_pattern>_lb): Likewise.
