I find there are no width 2 and 6 in x86 asm codes, so i remove 2 and 6.
After your remind i find neon codes have 2 and 6.
I will fix this in patch v2.

Why not include block width 2 and 6? I notice that there are already some 
optimization code for that.

[FFmpeg-devel] [PATCH] checkasm/hevc_mc : add hevc_mc for checkasm

2018-04-08 Thread Yingming Fan

From: Yingming Fan 

---
 Hi, there.
 I plane to submit our arm32 neon codes for qpel and epel.
 While before this i will submit hevc_mc checkasm codes.
 This hevc_mc checkasm codes check every qpel and epel function, including 8 10 
and 12 bit.
 Passed test by using 'checkasm --test=hevc_mc' under Linux x86_64 MacOS x86_64 
and Linux arm64 platform.
 Also passed FATE test.
