Subject: [PATCH 12/43] i386: Emulate MMX vec_dupv2si with SSE
Date: Sun, 10 Feb 2019 00:20:00 -0000 [thread overview]
Message-ID: <20190210001947.27278-13-hjl.tools@gmail.com> (raw)
In-Reply-To: <20190210001947.27278-1-hjl.tools@gmail.com>
Emulate MMX vec_dupv2si with SSE. Only SSE register source operand is
allowed.
PR target/89021
* config/i386/mmx.md (*vec_dupv2si): Changed to
define_insn_and_split and also allow TARGET_MMX_WITH_SSE to
support SSE emulation.
* config/i386/sse.md (*vec_dupv4si): Renamed to ...
(vec_dupv4si): This.
