Subject: Callgrind: Remove ifdef'ed-out, non-working code.
X-Git-Tag: svn/VALGRIND_3_5_0~1032
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=70084d4fa2ed8c252abfe1cb5837bb7329287008;p=thirdparty%2Fvalgrind.git

Callgrind: Remove ifdef'ed-out, non-working code.

Rechecking the diff of r9080 on the mailing list, I thought
I forgot to replace "|" with "+" in one spot. But that was part
of not-used code, so it actually does not matter.
So better get rid of this code part at all (no need to backport ;-).
