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. --- .gitignore | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to '.gitignore') diff --git a/.gitignore b/.gitignore index 02379a3b..9e530127 100644 --- a/.gitignore +++ b/.gitignore @@ -28,12 +28,18 @@ Makefile.config compcert.ini ia32/ConstpropOp.v ia32/SelectOp.v +ia32/SelectLong.v powerpc/ConstpropOp.v powerpc/SelectOp.v +powerpc/SelectLong.v arm/ConstpropOp.v arm/SelectOp.v +arm/SelectLong.v +x86_64/ConstpropOp.v +x86_64/SelectOp.v +x86_64/SelectLong.v backend/SelectDiv.v -backend/SelectLong.v +backend/SplitLong.v backend/CMlexer.ml backend/CMparser.ml backend/CMparser.mli -- cgit
