Subject: [Qemu-devel] [PATCH 06/13] linux-user/sparc: Use WREG constants in sparc/target_cpu.h
Date: Sun, 19 May 2019 13:19:46 -0700	[thread overview]
Message-ID: <20190519201953.20161-7-richard.henderson@linaro.org> (raw)
In-Reply-To: <20190519201953.20161-1-richard.henderson@linaro.org>

This fixes a naming bug wherein we used "UREG_FP" to access the
stack pointer.  OTOH, the "UREG_FP" constant was also defined
incorrectly such that it *did* reference the stack pointer.

Note that the kernel legitimately uses the name "FP", because it
utilizes the rolled stack window in processing the system call.
