Subject: Align pointers by 16 bytes boundary.
X-Git-Tag: 1.0.0~580
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0ea297d18f73e96247af1081993a05a36f75ccee;p=thirdparty%2Frspamd.git

Align pointers by 16 bytes boundary.

Many operations on x86 are much faster if the pointers are aligned
properly. Obviously, that would increase memory usage slightly, however,
rspamd always prefers speed to compactness.
