Willy Tarreau 84340d108b OPTIM: buffers: avoid a useless wrapping check for ofs == 0 ... As mentioned in previous commit, b_peek_ofs() performs a wrapping check but is often called with ofs == 0 as a constant. We can detect this case with __builtin_const_p() so it makes sense to use it. A test shows a size reduction of about 320 bytes, which is not much, but it happens in hot code paths, and each 16 bytes reduction indicates an eliminated conditional branch. Some clear winners are ci_getblk_nc() (-48 bytes), h2c_dec_hdrs (-141B), h1_copy_msg_data (-124B), tcpcheck_spop_expect_hello (-80B), h1_parse_msg_data (-44B). These ones will definitely benefit from doing less conditional jumps.		2024-10-18 18:42:47 +02:00
