From ac22318350b43bf7a4d72ed620365652cf222e9e Mon Sep 17 00:00:00 2001 From: Segher Boessenkool Date: Wed, 27 Jan 2016 20:44:31 +0100 Subject: [PATCH] rs6000: Put back the 's' output modifier It turns out the 's' output modifier is used in some glibc math code, and is in an installed header even. So let's put it back, it is much less of a burden supporting it a bit longer than to deal with the fallout. (It is also being fixed for glibc.) * config/rs6000/rs6000.c (print_operand): Rollback 's' removal.
