2018-11-01Provide a bit more clarity in the README file for updating.Dale Curtis
BUG=766721 Change-Id: I0d62c8e718714ad227f579d5c41ed34a77c47110
2018-11-01Fix windows build warning / error.Dale Curtis
2018-11-01Just use the built-in msvc.h instead of a hand generated Windows one.Dale Curtis
Per local benchmarks on test/avx512f.asm, a config.h generated using Cygwin plus clang-cl yielded a compilation time of ~450ms, while just using the built in msvc.h yielded ~405ms. So this is a no brainer: one less platform to generate and it's faster. BUG=766721 Change-Id: Ic6e930bce1a99adef037ac3fd56fef205696febc
2018-11-01Fix comment characters in config.hDale Curtis
2018-11-01Merge "Add codereview.settings file to suppress warning spam."Dale Curtis
2018-11-01Change config.h into a platform specific includer. Mac needs config.Dale Curtis
Unfortunately Mac needs its own build config, possibly Windows does too, so we need to create special configs per platform. Since the nasm source also explicitly include "config/config.h" we need to change the base config.h into one that includes the right platform config. This only fixes Mac for the moment, I'll send a fix for Windows once I've tried clang-cl on my Windows machine. At present the config-win.h file is just a copy of the Linux one.

2018-11-01Add codereview.settings file to suppress warning spam.Dale Curtis
I don't think this is used for anything anymore, but this clones the file from the ffmpeg repository to avoid spam when operating with some depot tools. BUG=766721 R=davidben Change-Id: I424d550edf59c47b1c764e9cf8e68b8ac83140f7
2018-10-31Add all the chromium stuff necessary to build nasm.Dale Curtis
This adds the BUILD file and configuration davidben at chromium.org wrote originally on https://chromium-review.googlesource.com/c/chromium/src/+/1119211 This is the last CL enabling nasm usage in Chromium (fingers crossed), but may need some tweaks to build on Windows mac. A subsequent Chromium CL adding the DEP will test this theory. BUG=766721 Change-Id: I481fc8d7f1747dad74cd0a02a251a65cfd78a134
2018-10-31Add all sources generated by "make perlreq"Dale Curtis
This step is required to turn source templates into sources. A later commit will document this process in README.chromium. This is one of the initial commits preparing NASM for use in Chrome. BUG=766721
2018-10-31Apply deterministic build patch.Dale Curtis
This removes __DATE__ from a few places to ensure the build is always the same. Patch originally authored by davidben at chromium.org This is one of the initial commits preparing NASM for use in Chrome. BUG=766721 Change-Id: I4217f9ffed1455b8f244b024dc10dbb8c5c0664d
2018-10-31Update .gitignore not to ignore generated files Chrome needs.Dale Curtis
By default any file generated by "make perlreq" is hidden by the .gitignore. This may require ongoing maintanence, so a PRESUBMIT has been added to prevent future regressions. This is the first of the commits preparing NASM for use in Chrome. BUG=766721 TEST=none Change-Id: Ib6cae0b2e6ad0420185a01497e2184c094cc105e

2018-10-28misc: Nindent -- Drop expand tabs with space optionCyrill Gorcunov
Currently out code is rather a mix of space/tabs with sometime different indent level. Mostly because some of developers are came from kernel space. Lets shift to kernel coding standart with small steps, file by file. It really helps when you're sitting in front of laptop more than 10 hours long.

All include paths to nasm must already have a trailing separator prefix which is uncommon among tools.
