Subject: Add the sqlite3VdbeLoadString() and sqlite3VdbeMultiLoad() routines to help
X-Git-Tag: version-3.9.0~158
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=076e85f59ce4b477ff6b979596515769e69c41aa;p=thirdparty%2Fsqlite.git

Add the sqlite3VdbeLoadString() and sqlite3VdbeMultiLoad() routines to help
with code generation, especially on PRAGMAs.  Rename sqlite3VdbeAddGoto()
to just sqlite3VdbeGoto().
