Subject: [PATCH 9/9] avutil/x86/asm: Remove wrong comment, rename FF_REG_sp
Before FFmpeg commit 531b0a316b24f00965cd8a88efdbea2c6d63147f,
FFmpeg used REG_SP as macro for the stack pointer, yet this
clashed with a REG_SP define in Solaris system headers, so it
was changed to REG_sp and a comment was added for this.
Libav fixed it by adding an FF_ prefix to the macros in
1e9c5bf4c136fe9e010cc8a7e7270bba0d1bf45e. FFmpeg switched
to using these prefixes in 9eb3da2f9942cf1b1148d242bccfc383f666feb6,
using FF_REG_sp instead of Libav's FF_REG_SP. In said commit
the comment was changed to claim that Solaris system headers
define FF_REG_SP, but this is (most likely) wrong.
This commit removes the wrong comment and renames the (actually unused)
macro to FF_REG_SP to make it consistent with FF_REG_BP.

AAC decoder in ffmpeg but it's still useful to
have FDK-AAC available for decoding when running into edge cases on the native
AAC decoder, or to decode USAC while the new decoder is under development, etc.

That is nothing that 'professionals' should pay out of their budget or

This is comparing int with uint64_t. We should probably just use int
