Subject: When compiling with VDBE_PROFILE, add the sqlite3NProfileCnt global variable
X-Git-Tag: version-3.23.0~137
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=35043cc32a4717edcc36153b2a1ced67d8750232;p=thirdparty%2Fsqlite.git

When compiling with VDBE_PROFILE, add the sqlite3NProfileCnt global variable
which can be used to measure per-opcode values other than elapse time, if
non-zero.
