From e637d041c5c2ee3a3ed395a7dab6c9101e8eb16c Mon Sep 17 00:00:00 2001 From: Xavier Leroy Date: Sat, 1 Oct 2016 17:25:18 +0200 Subject: Support for 64-bit architectures: generic support - Introduce Archi.ptr64 parameter. - Define module Ptrofs of integers as wide as a pointer (64 if Archi.ptr64, 32 otherwise). - Use Ptrofs.int as the offset type for Vptr values and anywhere pointer offsets are manipulated. - Modify Val operations that handle pointers (e.g. Val.add, Val.sub, Val.cmpu) so that in 64-bit pointer mode it is the "long" operation (e.g. Val.addl, Val.subl, Val.cmplu) that handles pointers. - Update the memory model accordingly. - Modify C operations that handle pointers (e.g. addition, subtraction, comparisons) accordingly. - Make it possible to turn off the splitting of 64-bit integers into pairs of 32-bit integers. - Update the compiler front-end and back-end accordingly. --- backend/Debugvar.v | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'backend/Debugvar.v') diff --git a/backend/Debugvar.v b/backend/Debugvar.v index 5d31831a..1f361030 100644 --- a/backend/Debugvar.v +++ b/backend/Debugvar.v @@ -136,7 +136,7 @@ Definition kill_at_call (s: avail) : avail := Definition eq_arg (a1 a2: builtin_arg loc) : {a1=a2} + {a1<>a2}.
