From b84b4b4b63aa13dd3257827ec0b0b777a1fbe159 Mon Sep 17 00:00:00 2001 From: Luc Van Oostenryck Date: Sat, 4 Jul 2020 15:05:37 +0200 Subject: add memory asm constraint for S390 The 'Q', 'R', 'S' & 'T'' asm constraint are used for for memory operands on S390 but only 'Q' belong to the 'common constraints'. Fix this by handling the 3 others with an arch-specific method.
