This fixes the typelinker test, but not the linking error in
ruamoko/game that it was supposed to represent. I guess there's
something more going on (maybe type encoding relocation issues).
Fixes#6
It turned out that the problem with @zero was caused by initial type
chaining occurring before the structures had been initialized and thus
the linker's @zero type encoding string was incorrect: {?=} instead of
{tag @zero-}, thus when the actual type encoding supplied by an object
file came along (with the correct encoding string), it wasn't found.
It is now "consistent" with the rest of the type building in that it
uses find_type(append_type(return, params)) like the C version, thus
allowing append_type to do its thing with type aliases. This fixes the
overload test.
This is a bit of a weird one because it's a combination of the aliasing
code and mixing C prototypes with QuakeC function definitions, and the
function type rebuilding in qc-parse.y not being very "consistent" in
its abuse of the type system.
The full_type branch of an alias splitter (alias with null name) needs
to mirror the clean side up to the type alias. It is causing problems
with functions, but that's expected because parameters complicate
things.
It's not connected up yet because I'm unsure of just where to put things
(it gets messy fast), but just being able to see the structure of
complex types is nice.
This eases type unaliasing on functions a little.
Still more to to go, but this fixes a really hair-pulling bug: linux's
heap randomiser was making the typedef test fail randomly whenever
typedef.qfo was compiled.
When a type is aliased, the alias has two type chains: the simple type
chain with all other aliases stripped, and the full type chain. There
are still plenty of bugs in it, but having the clean type chain takes
care of the major issue that was in the previous attempt as only the
head of the type-chain needs to be skipped for type comparison.
Most of the bugs are in finding the locations where the head needs to be
skipped.
All simple type checks are now done using is_* helper functions. This
will help hide the implementation details of the type system from the
rest of the compiler (especially the changes needed for type aliasing).
The view is recorded as having focus but is not given focus until the
parent view is actually in focus. This fixes the locals view not having
focus at startup and thus blocking F7.
