[PATCH] D141020: [X86][ABI] Clobber %RAX for preserve_allcc and preserve_mostcc CCs

[Juergen Ributzka via Phabricator via llvm-commits]

If this can be fixed without affecting any potential clients, then I am all for it. In hindsight it might have been better to make a use case specific calling convention instead and not a generic one that everyone could depend on. Oen possible solution would be to make a Chromium specific calling convention and also name it as such. This would provide clear expectations what it is intended for and how is supposed to use it. Furthermore this would give you the option of changing it in the future if the need should arise.
