Subject: Jack up the size of the translation cache from 16 MB to 40 MB (!).
X-Git-Tag: svn/VALGRIND_1_0_3~259
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=72c633f338d84ae369c73fcf26a22349fc967762;p=thirdparty%2Fvalgrind.git

Jack up the size of the translation cache from 16 MB to 40 MB (!).
This is needed to give reasonable behaviour for the insanity of a
Mozilla debug build, apparently even worse than the insanity of a
KDE 3 debug build.  Change some limit calculations to use double
rather than int, so as to avoid overflows.
