From 4622f49fd089ae47d0c853343cb0a05f986c962a Mon Sep 17 00:00:00 2001 From: Xavier Leroy Date: Fri, 27 Mar 2015 08:55:05 +0100 Subject: Extend annotations so that they can keep track of global variables and local variables whose address is taken. - CminorSel, RTL: add "annot" instructions. - CminorSel to Asm: use type "annot_arg" for arguments of "annot" instructions. - AST, Events: simplify EF_annot because constants are now part of the arguments. Implementation is not complete yet. --- backend/Liveness.v | 2 ++ 1 file changed, 2 insertions(+) (limited to 'backend/Liveness.v') diff --git a/backend/Liveness.v b/backend/Liveness.v index 3a5bde97..ce1a798a 100644 --- a/backend/Liveness.v +++ b/backend/Liveness.v @@ -93,6 +93,8 @@ Definition transfer reg_list_live args (reg_sum_live ros Regset.empty) | Ibuiltin ef args res s => reg_list_live args (reg_dead res after) + | Iannot ef args s => + reg_list_live (params_of_annot_args args) after | Icond cond args ifso ifnot => reg_list_live args after | Ijumptable arg tbl => -- cgit
