From 08c91ab698c91dc4b8fbc597c03ac1ca10eb403c Mon Sep 17 00:00:00 2001 From: Dmitry Vyukov Date: Sat, 2 Sep 2017 13:34:24 +0200 Subject: sys: support ptr64 type ptr64 is like ptr, but always takes 8 bytes of space. Needed for some APIs. Unfortunately, most of these APIs use buffer type, so we can't use ptr64 immidiately. --- pkg/compiler/testdata/errors.txt | 4 ++++ pkg/compiler/types.go | 6 +++++- 2 files changed, 9 insertions(+), 1 deletion(-) (limited to 'pkg/compiler') diff --git a/pkg/compiler/testdata/errors.txt b/pkg/compiler/testdata/errors.txt index d5a596457..68c9895bf 100644 --- a/pkg/compiler/testdata/errors.txt +++ b/pkg/compiler/testdata/errors.txt @@ -133,6 +133,10 @@ s6 { f1 int8 } [align_foo] ### bad struct s6 alignment foo +s7 { + f1 ptr64[in, int32] +} + u3 [ f1 int8 f2 int32 diff --git a/pkg/compiler/types.go b/pkg/compiler/types.go index 710bc1b60..de663f61e 100644 --- a/pkg/compiler/types.go +++ b/pkg/compiler/types.go @@ -74,11 +74,15 @@ var typeInt = &typeDesc{ } var typePtr = &typeDesc{ - Names: []string{"ptr"}, + Names: []string{"ptr", "ptr64"}, CanBeArg: true, Args: []namedArg{{"direction", typeArgDir}, {"type", typeArgType}}, Gen: func(comp *compiler, t *ast.Type, args []*ast.Type, base sys.IntTypeCommon) sys.Type { base.ArgDir = sys.DirIn // pointers are always in + base.TypeSize = comp.ptrSize + if t.Ident == "ptr64" { + base.TypeSize = 8 + } return &sys.PtrType{ TypeCommon: base.TypeCommon, Type: comp.genType(args[1], "", genDir(args[0]), false), -- cgit mrf-deployment
