Subject: [PATCH 01/66] perf tools: Fix bug in isupper() and islower()
From: Sukadev Bhattiprolu <sukadev@...ux.vnet.ibm.com>
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.
