This will be used by fgCanFastTailCall to correctly determine whether an arm64 or x64 linux caller/callee can fastTailCall. It is also a workaround to #12468 to catch early any slot shuffling that would happen in LowerFastTailCall. Which currently assumes all parameters are one slot size.

did this not ship with .net core 2.1.12? |
|
This fix should be in 2.1.12 (and in 2.2.6), but doesn't seem to be called out in the release notes for either. @vivmishra can you check if #24858 (2.1) and #24954 (2.2) was included in the releases but overlooked in the notes? |

Those two PRs did not have correct label or milestone set. I have fixed that now and added CoreCLR to rel notes. Cc: @leecow ; @RussKeldorph |
