Subject: [PATCH 26/41] i386: Emulate MMX umulv1siv1di3 with SSE2
Date: Mon, 18 Feb 2019 18:44:00 -0000 [thread overview]
Message-ID: <20190218183657.16296-27-hjl.tools@gmail.com> (raw)
In-Reply-To: <20190218183657.16296-1-hjl.tools@gmail.com>
Emulate MMX umulv1siv1di3 with SSE2. Only SSE register source operand
is allowed.
PR target/89021
* config/i386/mmx.md (sse2_umulv1siv1di3): Add SSE emulation
support.
