Hi,
I am working on a project that would collect AST info
and use it 'offline'. I wonder if it is possible to
use some parts of gcc as a dynamic library, to parse
the tree nodes and gimple statements.
For example, I have this naive function to get a field offset:
static unsigned long get_field_offset(tree field)
{
unsigned long ret = 0;
if (DECL_FIELD_OFFSET(field)) {
ret += TREE_INT_CST_LOW(DECL_FIELD_OFFSET(field)) * 8;
}
if (DECL_FIELD_BIT_OFFSET(field)) {
ret += TREE_INT_CST_LOW(DECL_FIELD_BIT_OFFSET(field));
}
return ret;
}
It may work well for some cases, I doubt that it can handle
all cases.
If I can use part of gcc as a dynamic library, it would be quite
easy to parse these tree nodes and gimple statements by using the
internal functions.
Thanks.
