From c971112be543c579d9257d7d6951de0c1d6f9615 Mon Sep 17 00:00:00 2001 From: Austin Clements Date: Tue, 18 Nov 2014 15:18:52 -0500 Subject: [dev.cc] 9a: make RET a synonym for RETURN; use "g" instead of "R30" Previously, 9a was the only assembler that had a different name for RET, causing unnecessary friction in simple files that otherwise assembled on all architectures. Add RET so these work on 9a. This also renames "R30" to "g" to avoid unintentionally clobbering g in assembly code. This parallels a change made to 5a.
