From 655a8355666bc3a238e6461409995f30817aff67 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Sat, 5 Nov 2016 00:21:33 +0000 Subject: [PATCH] re PR go/78172 (gen-sysinfo.go vs AIX cred.h) PR go/78172. libgo: avoid confusion in upcase_fields in mksysinfo.sh The mksysinfo.sh script could get confused when there were multiple types starting with the same name. I believe this is the underlying cause of GCC PR 78172. Also redirect a grep to /dev/null to avoid extraneous messages during the build.
