ObjFW  History of src/runtime/runtime-private.h of 3de549d6a5689ce6

This explicitly excludes threading.h, as adding nullability annotations
requires adding them everywhere in the file. However, the types in there
are implementation defined, and might be pointers or not: Adding none
when it's a pointer would be an error, and adding one when it's not a
pointer would be an error, too. file: [1aa5ac440a] check-in: [c5b3c8ea87] user: js, branch: trunk, size: 6657 [annotate] [blame] [check-ins using] [diff]

Casts are now written like types in variable declarations. file: [a994a21929] check-in: [4af49a13c3] user: js, branch: trunk, size: 5813 [annotate] [blame] [check-ins using] [diff]

This is necessary for ObjC++ with GCC, as otherwise, this generates an
error. Since the objc_abi_module struct is private anyway, there is not
much reason to have the argument of that type. file: [8959ceec24] check-in: [4e40a57efa] user: js, branch: trunk, size: 5785 [annotate] [blame] [check-ins using] [diff]

Forgot to add 2017, even though I already did quite some changes in
2017. file: [26968fda37] check-in: [44f45c2e35] user: js, branch: trunk, size: 5841 [annotate] [blame] [check-ins using] [diff]

Multiline preprocessor directives now always indent the continued lines
by 4 spaces. The only exception are defines that define to code blocks:
Those are still indented by a tab in order to align with the rest of the
code. file: [c0bf05887e] check-in: [543eb96c02] user: js, branch: trunk, size: 5835 [annotate] [blame] [check-ins using] [diff]

(U)INT_FAST*_MAX is broken on Android, which makes (u)int_fast*_t
dangerous to use while it does not provide any real speed benefit. file: [26a5f2070f] check-in: [d3158d091f] user: js, branch: trunk, size: 5776 [annotate] [blame] [check-ins using] [diff]

While at it, also update the mail address. file: [569575cc7f] check-in: [cec0f072f8] user: js, branch: 0.8, size: 5971 [annotate] [blame] [check-ins using] [diff]

* dtable.m is now the old sparse array, using IMP as type for values and
thus not violating the C standard anymore (functions may not be stored
in void*)
* New sparsearray.m which can work with any size, based on the sparse
array from the fast path of class.m
* Fast path of class.m now uses the new sparsearray.m file: [bdd53fa1db] check-in: [1ebb9eb7b3] user: js, branch: trunk, size: 5963 [annotate] [blame] [check-ins using] [diff]

This should improve the performance for the GCC ABI, as
objc_classname_to_class() is used for all sorts of class lookups, e.g.
objc_lookup_class().

As this performance improvement needs RAM, it is only used after 128
calls into objc_classname_to_class(), so that if the ObjFW ABI is used
and the user does not call into objc_getClass() or similar in a loop, no
memory is wasted.

Runtime internal usage of objc_classname_to_class() does not use the
fast path and does not count as a call into objc_classname_to_class().
The reason for this is that if the runtime calls
objc_classname_to_class(), it already has the lock and thus the
performance gain would be small, but it would waste memory. file: [3c88a5e1a9] check-in: [84a724dd4b] user: js, branch: trunk, size: 5194 [annotate] [blame] [check-ins using] [diff]

This also improves the check for the ABI. file: [a0b575feaf] check-in: [8108a32927] user: js, branch: trunk, size: 5193 [annotate] [blame] [check-ins using] [diff]

Checking at configure time can potentially break universal builds. file: [630ce5911a] check-in: [a4f1bd6c08] user: js, branch: trunk, size: 5120 [annotate] [blame] [check-ins using] [diff]

The only places where BOOL is left are those where they are required by
the ABI. file: [466c124f70] check-in: [c5ef582958] user: js, branch: trunk, size: 4743 [annotate] [blame] [check-ins using] [diff]

ERROR seems to be defined on MinGW32 and it's likely that it's also used
on other systems, thus it's better to prefix it with OBJC_. file: [fdc49ba79e] check-in: [345eb93240] user: js, branch: trunk, size: 5256 [annotate] [blame] [check-ins using] [diff]

For consistency. file: [cfeaa72523] check-in: [963db3089f] user: js, branch: runtime, size: 5249 [annotate] [blame] [check-ins using] [diff]

This is no longer done in objc_msg_lookup() and thus allows direct class
references. file: [0a8ea1ad61] check-in: [dcf845546a] user: js, branch: runtime, size: 5251 [annotate] [blame] [check-ins using] [diff]

It seems Clang sets flags in the lower 8 bits, so they shouldn't be used
for flags that the runtime sets. file: [e12f9f95c1] check-in: [1b3d035041] user: js, branch: runtime, size: 4979 [annotate] [blame] [check-ins using] [diff]

We now have OBJC_CLASS_INFO_{SETUP,LOADED,INITIALIZED}. file: [5779ba0dc9] check-in: [5a719c9b1f] user: js, branch: runtime, size: 4974 [annotate] [blame] [check-ins using] [diff]
