Subject: [PATCH 27/40] i386: Emulate MMX ssse3_ph<plusminus_mnemonic>wv4hi3 with SSE
Date: Thu, 14 Feb 2019 12:33:00 -0000	[thread overview]
Message-ID: <20190214123031.13301-28-hjl.tools@gmail.com> (raw)
In-Reply-To: <20190214123031.13301-1-hjl.tools@gmail.com>

Emulate MMX ssse3_ph<plusminus_mnemonic>wv4hi3 with SSE by moving bits
64:95 to bits 32:63 in SSE register.  Only SSE register source operand
is allowed.

	PR target/89021
	* config/i386/sse.md (ssse3_ph<plusminus_mnemonic>wv4hi3):
	Changed to define_insn_and_split to support SSE emulation.
