[FFmpeg-devel] [PATCH] Fix gas-preprocessor to translate .rdata sections for armasm and armasm64

[Lukas Fellechner]

Compiling FFmpeg with gas-preprocessor.pl and armasm or armasm64 fails since FFmpeg 4.2.

New .rdata sections have been added in ARM NEON assembly code (e.g. libavutil/aarch64/asm.S).
This fix allows gas-preprocessor to translate those sections to armasm compatible code.

Gas-preprocessor is maintained in https://github.com/FFmpeg/gas-preprocessor
