ObjFW  History of src/runtime/private.h of 93c947c919dc6ddb

This will be moved to the "amiga-library" branch entirely in order to
not block the 1.0 release, as this is still far from finished. file: [7ee10f418d] check-in: [f0b0aacf36] user: js, branch: trunk, size: 9264 [annotate] [blame] [check-ins using] [diff]

It's just a less awkward name and also what the BSDs use. file: [9ac7fac548] check-in: [b7a4e61b88] user: js, branch: trunk, size: 11687 [annotate] [blame] [check-ins using] [diff]

There is nothing left that needs errno. file: [67e48517bd] check-in: [8c90e88939] user: js, branch: trunk, size: 11418 [annotate] [blame] [check-ins using] [diff]

This prevents leaking resources like open files. file: [62a0f3f2e0] check-in: [169832c303] user: js, branch: trunk, size: 11536 [annotate] [blame] [check-ins using] [diff]

This is unused now that only the Apple runtime can be used on macOS. file: [8bfde7861e] check-in: [5672243f7f] user: js, branch: 1.0, size: 11114 [annotate] [blame] [check-ins using] [diff]

If it is an inline, changing how tagged pointers work internally would
break the ABI and require recompiling everything, making future changes
harder. file: [7f0c22271c] check-in: [2fee820b5d] user: js, branch: trunk, size: 11195 [annotate] [blame] [check-ins using] [diff]

The newest compilers for macOS/PowerPC, Apple GCC 4.0.1 and Apple GCC
4.2.1, both fail to compile any code that contains fast enumeration when
using -fgnu-runtime (both crash with a bus error). This means that using
the ObjFW runtime on macOS/PowerPC is no longer possible since ObjFW
started requiring ObjC 2.

macOS/PowerPC with the Apple runtime is still fully supported. file: [44543549b6] check-in: [3580326d70] user: js, branch: trunk, size: 11129 [annotate] [blame] [check-ins using] [diff]

This already makes tagged pointers work in the non-assembly lookup. file: [e3fff27493] check-in: [8707dd73c4] user: js, branch: tagged-pointers, size: 11282 [annotate] [blame] [check-ins using] [diff]

This way the runtime's linklib will use the ones passed to the ObjFW
.library. file: [6a201be4b3] check-in: [45a8b2333d] user: js, branch: amiga-library, size: 11184 [annotate] [blame] [check-ins using] [diff]

This avoids needing to #undef std{in,out,err} and then providing a new
symbol. file: [5d82a9b9bc] check-in: [514944f1ea] user: js, branch: amiga-library, size: 11131 [annotate] [blame] [check-ins using] [diff]

tlskey.m used OFMapTable only on AmigaOS. This became a problem when
autorelease pools were moved into the runtime, as autorelease pools use
TLS. The build then broke, as there suddenly was a dependency from the
runtime on ObjFW.

This now uses the hashtable from the runtime and also no longer uses
OFList, thus fixing the build. As we always use the runtime on AmigaOS
anyway, this is fine. file: [82de8c2339] check-in: [49aee5736e] user: js, branch: trunk, size: 11152 [annotate] [blame] [check-ins using] [diff]

amiga-gcc now links in __init_eh(). However, since we init EH ourselves,
there's no need for it, so we replace it with an empty one. file: [62b52db4cc] check-in: [7342a6e98b] user: js, branch: trunk, size: 8771 [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: [88abdbc6a0] check-in: [ede088a30d] user: js, branch: trunk, size: 8978 [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: [69f97ea107] check-in: [ef6d69931e] user: js, branch: trunk, size: 8798 [annotate] [blame] [check-ins using] [diff]

The only reason the runtime should ever terminate the process is because
a fatal error occurred, and for that it should use abort(). file: [9809c03572] check-in: [a37a78d51b] user: js, branch: trunk, size: 8759 [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: [5f7c093a7a] check-in: [482698c5be] user: js, branch: trunk, size: 12445 [annotate] [blame] [check-ins using] [diff]

They are still required for the function table in amiga-library.m. file: [86b6d19cbd] check-in: [86863a8845] user: js, branch: trunk, size: 10693 [annotate] [blame] [check-ins using] [diff]

This adds the same workaround for objc_enumerationMutation() as for
objc_exception_throw(). file: [457aeb2c70] check-in: [dff419362e] user: js, branch: trunk, size: 10524 [annotate] [blame] [check-ins using] [diff]
