ObjFW  History of src/runtime/lookup.m of e061c2b66e539d23

This is more compatible with the various conventions used on various
systems. file: [f359b0b2e3] check-in: [79fe29dbf4] user: js, branch: trunk, size: 4837 [annotate] [blame] [check-ins using] [diff]

This now calls +[initialize] several times on the same class if it is
unimplemented in one or more of the classes in the chain, to match the
behavior of the Apple runtime. While the behavior before was safer, it
can lead to testing against the ObjFW runtime and everything working,
but then failing when trying to use it with the Apple runtime. file: [15533381ae] check-in: [ede088a30d] user: js, branch: trunk, size: 4838 [annotate] [blame] [check-ins using] [diff]

ObjFW_RT used to be a separate project that followed the BSD style, as
it was written in pure C, while ObjFW's style is based on the BSD style
with changes to make it a better fit for Objective-C. This commit
changes ObjFW_RT to use the same style as ObjFW. file: [5c7645fb2a] check-in: [ef6d69931e] user: js, branch: trunk, size: 4932 [annotate] [blame] [check-ins using] [diff]

This currently uses __saveds on all exported functions for simplicity.
As an optimization, __saveds can be removed from some functions later
after careful verification that no code path starting from that function
accesses any data. file: [2d11be3866] check-in: [482698c5be] user: js, branch: trunk, size: 4787 [annotate] [blame] [check-ins using] [diff]

As we define the ABI, we can just replace BOOL with bool everywhere,
including in ObjFW itself. For the Apple platforms where BOOL and bool
are different, this is not a problem as BOOL and bool are passed and
returned the same way in the ABI.

This still defines BOOL to bool for compatibility, except on AmigaOS and
Wii, which both have its own BOOL type. file: [107b957fe8] check-in: [fe2cbe0021] user: js, branch: trunk, size: 4681 [annotate] [blame] [check-ins using] [diff]

This also renames ObjFW-RT to ObjFW_RT, as hyphens should not be in
framework names. file: [d66050c602] check-in: [0f42b0eafd] user: js, branch: trunk, size: 4681 [annotate] [blame] [check-ins using] [diff]

This is required to create a .library on MorphOS. file: [5175096ba7] check-in: [79011c5f56] user: js, branch: trunk, size: 4723 [annotate] [blame] [check-ins using] [diff]

Forgot to add 2017, even though I already did quite some changes in
2017. file: [b142ca0e6c] check-in: [44f45c2e35] user: js, branch: trunk, size: 4665 [annotate] [blame] [check-ins using] [diff]

While at it, also update the mail address. file: [9bfc2a372f] check-in: [2a27cf3000] user: js, branch: trunk, size: 4659 [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: [c4fa11142c] check-in: [1ebb9eb7b3] user: js, branch: trunk, size: 4574 [annotate] [blame] [check-ins using] [diff]

It behaves like in the Apple runtime now. file: [cccd16e367] check-in: [3cd9d0ad69] user: js, branch: trunk, size: 4592 [annotate] [blame] [check-ins using] [diff]

It matches the Apple API and ABI now and the forwarding handler itself
determines whether it should forward or not.

This moves handling of +[resolve{Class,Instance}Method:] to the runtime
and allows adding new kinds of forwarding without changing the runtime.

Also fixes a potential stack problem in the forwarding for MIPS. file: [5baad6528e] check-in: [0c332aa2d2] user: js, branch: trunk, size: 4453 [annotate] [blame] [check-ins using] [diff]

The assembly implementations of the lookup and forwarding still need to
be adjusted. Those just alias to the non-stret version for now so that
linking works, meaning the behaviour is still the same as without
support for objc_msg_lookup_stret for now. file: [1c3a42c0f8] check-in: [9713ad857d] user: js, branch: trunk, size: 3487 [annotate] [blame] [check-ins using] [diff]

The only places where BOOL is left are those where they are required by
the ABI. file: [7a62dc26ba] check-in: [c5ef582958] user: js, branch: trunk, size: 2524 [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: [ef50fd350e] check-in: [345eb93240] user: js, branch: trunk, size: 2511 [annotate] [blame] [check-ins using] [diff]

This is no longer done in objc_msg_lookup() and thus allows direct class
references. file: [584f60ba59] check-in: [dcf845546a] user: js, branch: runtime, size: 2432 [annotate] [blame] [check-ins using] [diff]

Subdirectories don't really work without traversing them and having a
Makefile in them and it's not really worth the effort for just 2 files. file: [29b33e14c4] check-in: [3dbfc001c0] user: js, branch: runtime, size: 1723 [annotate] [blame] [check-ins using] [diff]
