[09:04:05 CEST] <nevcairiel> you would think someone trying to report weird static analyzer findings would understand reference counted structures, but apparently not

[17:43:06 CEST] <durandal_1707> which SIMD instruction compares registers and raturns mask if < or > ?
[17:44:13 CEST] <Lynne> pcmpgt*
[20:16:29 CEST] <cone-953> ffmpeg 03Paul B Mahol 07master:79522411fa53: avfilter/vf_lenscorrection: make width/height int
[21:07:59 CEST] <durandal11707> how to use maskmovdqu ?
[21:10:16 CEST] <Lynne> don't unless you like your SIMD slow
[21:10:27 CEST] <nevcairiel> wasnt maskmov one of those instructions that are really only useful for compilers and not for SIMD writers
[21:10:40 CEST] <iive> it works great on Intel CPU's
[21:11:12 CEST] <iive> on "most" AMD cpu's it could make the SIMD code slower than plain C.
[21:12:38 CEST] <iive> (even if used ones or twice per stride).
[21:17:52 CEST] <cone-953> ffmpeg 03Michael Niedermayer 07master:0c07eb52050b: tools/target_dec_fuzzer: Also fuzz block_align
[21:17:53 CEST] <cone-953> ffmpeg 03Michael Niedermayer 07master:2d3ccfa86334: tools/target_dec_fuzzer: Also fuzz FF_COMPLIANCE_EXPERIMENTAL
[21:17:54 CEST] <cone-953> ffmpeg 03Michael Niedermayer 07master:cc50d113c88f: tools/target_dec_fuzzer: Also fuzz codec_tag
[21:22:30 CEST] <durandal11707> how to divide words in SIMD?
[21:22:41 CEST] <durandal11707> a / b
[21:24:18 CEST] <BtbN> you load the values in registers, and call the divide instruction?
[21:24:51 CEST] <durandal11707> how smart!
[21:25:30 CEST] <durandal11707> i need packed variant
[21:28:33 CEST] <Lynne> no integer simd divide
[21:29:11 CEST] <Lynne> you have to mult + right shift with magic constants
[21:30:36 CEST] <durandal11707> i have number ranging from 5 to 129 for division
[21:31:31 CEST] <Lynne> the divisor matters more
[21:32:04 CEST] <durandal11707> yes i divide with 5-129
[23:10:40 CEST] <durandal11707> michaelni: looks like AV_RSHIFT macro changes first operand if it is unsigned
[23:11:45 CEST] <durandal11707> actually it probably does not work with unsigneds at all
[23:13:30 CEST] <michaelni> yes
