Re: [webkit-dev] Transformations precision: double - float

What CPU executes single precision floating point values at the same speed as double precision? Here's a benchmark from NASA giving a comparison of single vs. double precision performance for one of their simulations. https://modelingguru.nasa.gov/docs/DOC-1664. Single precision maps better

Re: [webkit-dev] Int/FloatPoint and Int/FloatSize

Subtraction of two points should not equate to a size. That's would be unexpected behavior for anyone used to working in 2D space. Mathematically speaking point - point equates to a vector. When writing a vector math library there typically isn't a differentiation made between a point and a

[webkit-dev] WinCairo Maintainers

I was wondering who was in charge of WinCairo now. We at Sony have been using WinCairo to land anything that isn't specific to our own internal port but we don't have any intention to ship anything using it. We have some outstanding patches for the GitHub requirements repository,

Re: [webkit-dev] WinCairo Maintainers

@annulen I know you've mentioned conan.io before but I've never personally used it so I'm not sure how well it would fit with everything. It's something we can take a look at beforehand and see what it would take vs the single repository setup. @alexchristensen I can make a GitHub org push

Re: [webkit-dev] WebKit GPU rendering possibility

Re: [webkit-dev] WebCore/platform standalone library

I was the one who did the WebCore::PAL namespace so I wanted to chime in on why I went that route. We at Sony are newcomers to pushing to trunk so my explanation might be entirely too idealistic but here goes. I had thought of PAL as a library that is internal to WebCore that provides a clear

[webkit-dev] Intent to implement WebKit for Windows ports

Hi WebKittens, We over at Sony have been committing more resources to WebKit, from revitalizing the WinCairo port, rebooting the cURL network backend, and continued work on the PAL layer. We've had some developers looking at the possibility to move WinCairo from WebKitLegacy over to WebKit and

I took some time today to see how clang-tidy can be run on WebKit code and opened https://bugs.webkit.org/show_bug.cgi?id=171632 with some examples on how to run things. I also attached some output from the modernizer fixes that can be applied. I was thinking of running any code we move from

Did you happen to look at any sort of distributed build system? We use distributed builds here for WebKit and a full rebuild is pretty reasonable. That would negate the need to change how everything is done to get a unity build going. From: webkit-dev

Hi Michael, There are a couple problems with checking in a version of ICU. * Other libraries used by WebKit have dependencies on ICU. For our ports harfbuzz, libxml2, libxslt, libpsl and CFlite all require ICU. * ICU doesn't come with a CMake build system and its non-trivial to make one. We've
