From 0cb14750e7723c50011c6c9c73dca6e8608486e5 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Tue, 27 Sep 2016 15:08:51 +0000 Subject: [PATCH] MIPS/GCC/doc: Fix `d' constraint description Revert a part of the `d' constraint documentation update made with commit 111868 ("Use define_constraint for MIPS"), , , which inadvertently made the registers covered to be referred to as "address" rather than "general-purpose" registers, and then further clarify the set of registers allowed with MIPS16 code. * config/mips/constraints.md (d): Fix documentation. * doc/md.texi (Machine Constraints): Update accordingly.
