theraven 06ff4be6a9 More build system tidies. 15 years ago
thebeing ee7817cf57 Implement a hook that allows the compiler to register the aliases used with the 
@compatibility_alias directive so that they can be resolved at runtime.

theraven faa741b133 Added some header documentation for runtime functions. 15 years ago
theraven ff21fcc43d Added C++ include guards to capabilities.h 15 years ago
theraven 7336df75bc Added some more comments, C++ include guards around runtime.h. 15 years ago
theraven 2c21235cc2 Fix multiple include guard in capabilities.h. 15 years ago
theraven 73e1e2934b It turns out that Apple chose some confusing and non-intuitive semantics for 
catching Objective-C objects in C++ catch statements (i.e. they follow
Objective-C semantics, not C++ semantics, irrespective of whether you use C++
or ObjC syntax).  We now default to Apple-compatible behaviour, but provide a
function that allows users to select the sane semantics if they prefer.

Added a capability bit for the unified exception model, so code can require it.
This is not really required, since any code using it will link against the
ObjC++ personality function and will get a linker failure if it isn't supported.

Also enabled Objective-C++ stuff by default.  This adds a dependency on the C++
standard library (actually on libsupc++, but GNUstep Make wants to link against
libstd++ anyway), which is not ideal.  It can be disabled with:

$ gmake objectiver-cxx=no

I suggest that this is only done by people who know that they will never want
Objective-C++ support.

theraven e0d80861b5 Added some documentation. 15 years ago
theraven 8db63b976f Initial work on developer mode (allows classes to be replaced at run time with new versions, by cooperating IDEs). This support is part of ongoing work to provide fix-and-continue functionality with Clang / Cling and LanguageKit. 15 years ago
theraven bde6bf0e14 Fix truncated comment in header and 'worse than useless' macro. 
Both issues pointed out by Jens Ayton.

ericwa a7ea477400 libobjc2: put libobjc compatibility functions in runtime.h marked __attribute__((deprecated)) 15 years ago
theraven e70d00a76d Restore accidentally deleted toydispatch.h. 15 years ago
theraven 7be9f34619 Fixed @synchronize() with a class that has had an instance used for @synchronize(). 15 years ago
theraven ee32f78b0a Tweaked the GNUmakefile to (more or less) work with gcc. 
Fixed block introspection for the new (Apple-compatible) ABI.

theraven d70523947b Implement some missing runtime functions. 16 years ago
theraven 9c077368a8 Make sel_copyTypes_np() return the number of types in all cases. 16 years ago
theraven a029fb2af3 Expose sel_copyTypes_np(). 16 years ago
ericwa 7ce5a0ab11 libobjc2: make Object.h include runtime.h 16 years ago

theraven b1aa77e450 Commit some missing files. 16 years ago
theraven eb48fda62b Expose a function needed by GNUstep. 16 years ago
theraven e2d848467c Another try... 16 years ago
theraven 00004fe5f3 More tweaks to the GNU-compatibility encoding stuff. This API is too broken to use, but GNUstep seems to want it. 16 years ago
theraven 0177ef56e1 Tweak the type encoding stuff a bit. 16 years ago
theraven 5885fd196a Add defines for ObjC types (GNUstep apparently uses them, even though they are not part of the language spec, but the things that they define are, so they only serve to obfuscate code where they are used). 16 years ago
theraven bd58a33b84 Prevent accidental mixing of GNU runtime headers with GNUstep runtime.h. 16 years ago
theraven f43e7f6845 Fix typo. 16 years ago
theraven ab59ce1d33 Add feature test APIs to libobjc2. 16 years ago
theraven 77d02d075b Add some missing protocol introspection functions. 16 years ago
ericwa 52bdf1484f libobjc2: add dummy objc.h and objc-api.h headers which simply include runtime.h 16 years ago
theraven 0284155f2d Added a hook that defines the behaviour when you call a method with the wrong signature. 16 years ago
theraven e9b129d878 Added low memory profile to libobjc2. This uses a more NeXT-style dtable design, which gives better memory usage at the cost of (significantly) worse worst-case performance. The memory savings seem to be only about 10% in the apps I've tested (Gorm, edlc), so it's probably not worthwhile, but it might be useful for someone finding stuff is just starting to swap... 16 years ago
theraven 2cc96a6f7e Fix message forwarding by, for example, actually calling the public forwarding hook, instead of one that isn't exposed to GNUstep... 16 years ago
theraven fb474dd7f9 Removed hooks from runtime.h that are in hooks.h 16 years ago
theraven f375d20d7a Add support for catching C++ (and Java / Ada) exceptions in Objective-C. 16 years ago
theraven 07758fe521 Removed last bits of legacy code from libobjc2. Added new exception handling implementation. 16 years ago
theraven b1b9baf382 Finished rewrite of message sending. Deleted lots of legacy stuff. 16 years ago
theraven bb8cafaa15 Finished rewriting the loader. It's now cleanly separated into logically-separate components, so there's a chance it might actually be maintainable... 16 years ago
theraven de71ebb6b1 Rewritten class loading. 16 years ago
theraven 7f6f798074 Rewrote some of the class table code to be slightly cleaner. 16 years ago
theraven a9bdab1f44 Reverted last commit - breaks the build with clang. 
Fixed the definition of objc_msgSendSuper().

Tweaked the -dealloc implementation for hidden classes used for locking so that @synchronize(self) will work in a -dealloc method.

theraven ded142ebff Add empty sarray.h - for some reason GNUstep is trying to #include this file (no idea why, as nothing in GNUstep actually uses anything from it). Adding an empty version should prevent breakage for now. 16 years ago
theraven b04cccf46b Fixed some issues in runtime.c when looking up methods. This fixes some issues with DO. 
Removed GNU dtable and sparse array implementations, replaced entirely now with versions based on the Étoilé runtime.  Performance is roughly equivalent in microbenchmarks, memory usage is significantly lower (Gorm goes from 95MB to 50MB on my machine - this will be even more pronounced on 64-bit systems), which should improve cache usage considerably.  Still room for some performance tuning, however.

theraven 2d84b96a72 Tidied up some bits by creating private headers for private data structures. 
Imported selector table code frm the Étoilé runtime.  We can now make dispatch type dependent with a -D switch.  Not enabled yet, but it will be enabled in a warning mode soon - I consider preferable to the existing GNU and Apple solution of corrupting the stack.
