[FFmpeg-devel] [PATCH] Add support for "omp simd" pragma.

[Reimar Döffinger]

> If building with MSVC tools, yes you're right that armasm.exe/armasm64.exe takes a different syntax. But the gas-preprocessor tool (which is picked up automatically by our configure, one just needs to make sure it's available) handles expanding all the macros and rewriting directives into the armasm form, and feeding it to the armasm tools. Works fine and have done so for years. There's even a wiki page which tries to explain how to do it (although it's probably outdated in some aspects), see https://trac.ffmpeg.org/wiki/CompilationGuide/WinRT.

I went with the instructions in doc/platform.texi and that did not work at all,
It even tried to use cl.exe to compile the assembler files!

> All of these run with full assembly optimizations enabled. So please don't tell me that our assembly doesn't work on windows on arm, because it does, and it has for years.

My apologies. I’ll correct to: it doesn’t work using the instructions
shipping with the source code (as far as I can tell) :)
