>From fd349681226bf7b27c9d0f72b0f3941b5aa94f78 Mon Sep 17 00:00:00 2001 From: Sukadev Bhattiprolu <[email protected]> Date: Fri, 29 Mar 2013 12:14:43 -0700 Subject: [PATCH] perf: fix bug in isupper() and islower()
One of the reasons 'perf test' is failing on Power appears to be due to a bug in isupper(). isupper(c) and islower(c) should be checking 'c' against the mask 0x20. Instead they are checking sane_ctype[c] which causes isupper() to be true for lower case letters.
