Subject: mips32/mips64: Suppress race condition error.
X-Git-Tag: svn/VALGRIND_3_10_0~687
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=312c647a6e624e5e77b26303e400a183a172a0d6;p=thirdparty%2Fvalgrind.git

mips32/mips64: Suppress race condition error.

On MIPS architecture helgrind is showing race condition error in printf if
the printf is first time called from the child thread. If we call printf
from the main for the first time we will suppress this error on mips.
