From d9389827d21ba1adf0663d4122acfa467b2d7ad8 Mon Sep 17 00:00:00 2001 From: Yaxun Liu Date: Wed, 14 Mar 2018 15:02:28 +0000 Subject: CodeGen: Reduce LValue and CallArgList memory footprint before recommitting r326946 Recent change r326946 (https://reviews.llvm.org/D34367) causes regression in Eigen due to increased memory footprint of CallArg. This patch reduces LValue size from 112 to 96 bytes and reduces inline argument count of CallArgList from 16 to 8. It has been verified that this will let the added deep AST tree test pass with r326946. In the long run, CallArg or LValue memory footprint should be further optimized.
