[Qemu-devel] [PATCH v2 4/7] tests/tcg: target/mips: Add wrappers for MSA bit counting instructions |
Date: |
Wed, 13 Feb 2019 16:14:54 +0100 |
From: Aleksandar Markovic <address@hidden>
Add a header that contains wrappers around MSA instructions assembler
invocations. For now, only bit counting instructions (NLOC, NLZC, and
PCNT; each in four data format flavors) are supported.
