From 7967d1da7af01c49661241c47708caa6dec78adb Mon Sep 17 00:00:00 2001 From: =?utf8?q?Alex=20Benn=C3=A9e?= Date: Tue, 23 Mar 2021 16:52:54 +0000 Subject: [PATCH] linux-user/riscv: initialise the TaskState heap/stack info MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Arguably the target_cpu_copy_regs function for each architecture is misnamed as a number of the architectures also take the opportunity to fill out the TaskState structure. This could arguably be factored out into common code but that would require a wider audit of the architectures. For now just replicate for riscv so we can correctly report semihosting information for SYS_HEAPINFO.
