ObjFW  History of src/runtime/selector.m of 2e9336b1efd820b3

This is more compatible with the various conventions used on various
systems. file: [99b2d0f965] check-in: [79fe29dbf4] user: js, branch: trunk, size: 3651 [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: [6c2deedb05] check-in: [ef6d69931e] user: js, branch: trunk, size: 3503 [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: [7ad9a1d734] check-in: [482698c5be] user: js, branch: trunk, size: 3570 [annotate] [blame] [check-ins using] [diff]

This also renames ObjFW-RT to ObjFW_RT, as hyphens should not be in
framework names. file: [c1a16c1dcc] check-in: [0f42b0eafd] user: js, branch: trunk, size: 3464 [annotate] [blame] [check-ins using] [diff]

This is required to create a .library on MorphOS. file: [f5a125315c] check-in: [79011c5f56] user: js, branch: trunk, size: 3547 [annotate] [blame] [check-ins using] [diff]

Casts are now written like types in variable declarations. file: [57debffc40] check-in: [4af49a13c3] user: js, branch: trunk, size: 3448 [annotate] [blame] [check-ins using] [diff]

Forgot to add 2017, even though I already did quite some changes in
2017. file: [b4065297e3] check-in: [44f45c2e35] user: js, branch: trunk, size: 3442 [annotate] [blame] [check-ins using] [diff]

While at it, also update the mail address. file: [1df1d6cb9f] check-in: [2a27cf3000] user: js, branch: trunk, size: 3442 [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: [c0034eeff2] check-in: [1ebb9eb7b3] user: js, branch: trunk, size: 3432 [annotate] [blame] [check-ins using] [diff]

Not using -std=gnu11 means _GNU_SOURCE does not get defined anymore,
therefore this commit also adds the required feature defines for glibc.

Additionally, this adds of_strdup in macros.h, as strdup is an
extension. file: [915bbfe8d7] check-in: [2f5af58573] user: js, branch: trunk, size: 3333 [annotate] [blame] [check-ins using] [diff]

When a selector was created using sel_registerName(), it was not free'd
on exit, as selectors not created using sel_registerName did not need
any freeing. This adds a list of selectors created using
sel_registerName() and frees them on exit.

This is only relevant if objc_exit() is used to free all memory occupied
by the runtime. objc_exit() is only useful for debugging memory leaks,
so there was no real world effect. file: [743b892159] check-in: [0ede45ce93] user: js, branch: trunk, size: 3298 [annotate] [blame] [check-ins using] [diff]

The only places where BOOL is left are those where they are required by
the ABI. file: [64e4076187] check-in: [c5ef582958] user: js, branch: trunk, size: 2873 [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: [c767975d02] check-in: [345eb93240] user: js, branch: trunk, size: 2866 [annotate] [blame] [check-ins using] [diff]

The first was that sel_registerName would crash if no selector has ever
been registered before. This caused a crash on NetBSD in has_load, as
the first class being loaded there (Protocol) had no selectors and
has_load uses sel_registerName in order to get the load selector.

The second one was that the hashtable was read without a lock to see if
the selector has already been registered before. file: [f1aef89fda] check-in: [e5b241b72d] user: js, branch: trunk, size: 2851 [annotate] [blame] [check-ins using] [diff]

This way, the sparsearrays for the dtables should be smaller. file: [ce39c495db] check-in: [3f0b9df793] user: js, branch: runtime, size: 2789 [annotate] [blame] [check-ins using] [diff]
