GEP_tup_like finds interior pointers by creating a tuple of all the types
preceding the element it wants a pointer to, then asks for the size of that
tuple. This results in incorrect pointers when the alignment of that tuple
is not the alignment of the interior type you're getting a pointer to.
Under this scheme when parsing foo.rc the parser will also look for
foo.rs to fill in the crate-level module, and when evaluating a
directory module directive it will look for a .rs file with the
same name as the directory.
You almost never want a function with pinned type params. For
types, objects, resources, and tags, pinned types are actually often
more sane. For most of these, shared rarely makes sense. Only tricky
case is objs -- you'll have to think about the kinds you want there.
Issue #1076
Note: I found a bug in c-stack-cdecl which codes not permit such
native functions to be used as values. I added an xfail-test
(c-stack-as-value) documenting it.
In the main test, I call the wrapper instead of the native fn, as intended.
I also added an xfail-test that exercises the broken code path. Will
file a bug.
Description of the broken code path:
The code path is that when we look up the external identifier we go through
trans_external_path() -> type_of_ty_param_kinds_and_ty() ->
type_of_fn_from_ty() -> type_of_fn(), and type_of_fn() adds a lot of external
parameters. Problem is, I guess, that we don't pass the native ABI (or even the
fact that it's a native function!), just the types and kinds of the parameters.
there is one test failure, stdtest/sys.rs, which inexplicably
(thus far) fails to compile because it invokes
sys::rustrt::last_os_error() instead of invoking
sys::last_os_error(). If stdtest/sys.rs is updated to invoke
the wrapper, it passes. Still tracing the source of this error.
Had to ignore some task failure tests due to the current implementation
of spawn which guarantees that there's always something in the spawned
task that needs to be unwound.
Fixed some win-specific build problems.
also repair various errors in the parser related to such blocks.
rename checked_blk to default_blk to reflect the fact that it
inherits its purity from the surrounding context.
