| braderhart | Hello. Would you be willing to release a 64bit version of MuPDF 1.14.0 for Windows? | 16:50.11 |
| sebras | Robin_Watts: maybe we ought to do both 32- and 64-bit releases for windows as braderhart seems to indicate? | 18:23.40 |
| Robin_Watts | I have no objection to that. | 18:24.04 |
| sebras | Robin_Watts: is it useful? would e.g. the file API accept larger files or what would be the difference? | 18:24.12 |
| Robin_Watts | I think the file size we'd handle would be the same. | 18:24.46 |
| sebras | though, PDFs larger than 2Gbyte are a bit rare. | 18:24.48 |
| | ok. | 18:24.57 |
| | in that case, what'd be the difference? would there be a performance increase on 64-bit machines? | 18:25.47 |
| Robin_Watts | More memory availability. | 18:26.36 |
| sebras | Robin_Watts: it is not often that I hit any 2Gbyte or 4Gbyte limit rendering files. | 18:27.48 |
| Robin_Watts | indeed. | 18:27.56 |
| sebras | braderhart: is there some situation where the current 32-bit binary is causing you grief? | 18:28.06 |
| Robin_Watts | braderhart: What do you see the benefit of this being? | 18:28.07 |
| sebras | Robin_Watts: the request seems reasonable, but just adding another build to the release for no obvious benefit seems... wasteful. :) | 18:28.53 |
| Robin_Watts | Yeah, I'd like to understand what the perceived benefit is. | 18:29.12 |
| moolc | sebras: uhm.. i'd measure it... but 64bit builds would alleviate register starvation a bit... otoh the memory pressure will go up (pointers will take twice as much).. | 18:33.54 |
| sebras | moolc: if there's a performance increase that is significant that might motivate it. | 18:35.30 |
| moolc | sebras: i'd read the discussions on x32 ABI for linux, that (probably) contains some more (useful) info | 18:37.11 |
| Robin_Watts | Our tests with gs a while ago had the 64bit build as being slower. | 18:38.19 |
| | (fractionally) | 18:38.24 |
| moolc | Robin_Watts: forth/postscript (interpreters) in general take a hit due to higher memory pressure and lots of pointers | 18:39.10 |
| sebras | Robin_Watts: are you still around? | 23:10.12 |
| | if so perhaps I can interest you in a proposed bug fix? http://git.ghostscript.com/?p=user/sebras/mupdf.git;a=commitdiff;h=9b183c560ef9183f7d4ab32af56d8bad0b494f36;hp=cb530cdc26f5e04601f00140da02299b4b59a55b | 23:10.47 |
| | at least in reviewing it. :) | 23:10.52 |
| Robin_Watts | sebras: lgtm | 23:50.19 |
| | Forward 1 day (to 2018/11/01)>>> | |
