Bug ID: 161
Summary: GDC prevents backend from removing dead functions
Product: GDC
Version: development
Hardware: All
OS: All
Status: NEW
Severity: minor
Priority: Low
Component: gdc
Assignee: ibuc...@gdcproject.org
Reporter: johannesp...@gmail.com
Private functions which are never used could be removed by the GCC backend, but
we somehow prevent the backend from doing that.
Example: C
--------------
static void foo() {}
--------------
gcc -S -O test.c
D:
--------------
private void foo() {}
--------------
gdc -S -O test.c
The problem is probably in d-decls.cc(FuncDeclaration::toSymbol) and is one of
(or a combination of) these: TREE_PUBLIC set, TREE_USED set, TREE_STATIC not
set?
