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/PrintAsmaux.ml | 3 +++ 1 file changed, 3 insertions(+) (limited to 'backend/PrintAsmaux.ml') diff --git a/backend/PrintAsmaux.ml b/backend/PrintAsmaux.ml index 148c5300..b220659c 100644 --- a/backend/PrintAsmaux.ml +++ b/backend/PrintAsmaux.ml @@ -138,6 +138,9 @@ let cfi_section = let coqint oc n = fprintf oc "%ld" (camlint_of_coqint n) +let coqint64 oc n = + fprintf oc "%Ld" (camlint64_of_coqint n) + (** Programmer-supplied annotations (__builtin_annot). *) let re_annot_param = Str.regexp "%%\\|%[1-9][0-9]*" -- cgit
