[PATCH] target/loongarch: Use actual operand size with vbsrl check


From: Bibo Mao
Subject: [PATCH] target/loongarch: Use actual operand size with vbsrl check
Date: Thu, 12 Dec 2024 16:22:34 +0800

Hardcoded 32 bytes is used for vbsrl emulation check, there is
problem when options lsx=on,lasx=off is used for vbsrl.v instruction
in TCG mode. It injects LASX exception rather LSX exception.

Here actual operand size is used.
