L708: A valid list of constants as of libseccomp v2.5.0 is shown below.

This has to be updated to v2.6.0 (and we have to wait for v2.6.0 to be released)

@AkihiroSuda AkihiroSuda added this to the v1.2.0 milestone Mar 14, 2023

Hi AkihiroSuda,
ArchLOONG64 is used here, because the GOARCH name corresponding to the LoongArch64 architecture in golang is loong64.
The support for loong64 will also be integrated into libseccomp-go, and the corresponding PR is: seccomp/libseccomp-golang#106
I understand that it should be a better solution to keep the name of Arch consistent in these two projects.

The variable name here must correspond to the seccomp arch name, not the GOARCH name.
See ArchX86_64 vs amd64, ArchAARCH64 vs arm64.
