Subject: [PATCH 12/41] i386: Emulate MMX vec_dupv2si with SSE
Date: Sat, 16 Feb 2019 22:40:00 -0000 [thread overview]
Message-ID: <20190216224032.4889-13-hjl.tools@gmail.com> (raw)
In-Reply-To: <20190216224032.4889-1-hjl.tools@gmail.com>
Emulate MMX vec_dupv2si with SSE. Add the "Yw" constraint to allow
broadcast from integer register for AVX512BW with TARGET_AVX512VL.
Only SSE register source operand is allowed.
PR target/89021
* config/i386/constraints.md (Yw): New constraint.
* config/i386/mmx.md (*vec_dupv2si): Changed to
define_insn_and_split and also allow TARGET_MMX_WITH_SSE to
support SSE emulation.
