[PATCH v3 28/34] target/arm/tcg: Move v8m_stackcheck() from op_helper.c


From: Philippe Mathieu-Daudé
Subject: [PATCH v3 28/34] target/arm/tcg: Move v8m_stackcheck() from op_helper.c to m_helper.c
Date: Mon, 19 Jun 2023 17:55:04 +0200

No need to have the v8m_stackcheck() helper in the generic
op_helper.c, move it with the rest of the M-profile helpers.
