From ca80f1a05af1cfea4ee41221bf1f5923df41066c Mon Sep 17 00:00:00 2001 From: Daniel Sanders Date: Sat, 1 Nov 2014 17:38:22 +0000 Subject: [tablegen] Add CustomCallingConv and use it to tablegen-erate the outermost parts of the Mips O32 implementation Summary: CustomCallingConv is simply a CallingConv that tablegen should not generate the implementation for. It allows regular CallingConv's to delegate to these custom functions. This is (currently) necessary for Mips and we cannot use CCCustom without having to adapt to the different API that CCCustom uses. This brings us a bit closer to being able to remove MipsCC::analyzeCallOperands and MipsCC::analyzeFormalArguments in favour of the common implementation. No functional change to the targets.
