From 2e3df911c5bb8199b72427a36ce68a8fe2decf1f Mon Sep 17 00:00:00 2001 From: "Wladimir J. van der Laan" Date: Thu, 27 Jun 2019 02:34:54 -0700 Subject: [PATCH] disas/riscv: Fix `rdinstreth` constraint The constraint for `rdinstreth` was comparing the csr number to 0xc80, which is `cycleh` instead. Fix this.
