ObjFW  History of src/runtime/exception.m of 8b0ab1157cdedadf

A better approach would probably be to have a separate header which
makes some classes available to pure C. file: [0555413ebe] check-in: [14c70763b0] user: js, branch: trunk, size: 19879 [annotate] [blame] [check-ins using] [diff]

errno is problematic for Amiga libraries and is also not thread-safe on
some systems, even though it should. file: [50eac6751c] check-in: [5b37fbeb82] user: js, branch: trunk, size: 19890 [annotate] [blame] [check-ins using] [diff]

It seems to be garbage on some platforms and both libsupc++ and libobjc
don't check its return value either. file: [ff0a7a161b] check-in: [0d383aeb8a] user: js, branch: trunk, size: 19855 [annotate] [blame] [check-ins using] [diff]

This allows the runtime to only link against the parts it needs, without
pulling in unnecessary parts like thread spawning, TLS and conditions. file: [00f195dbf4] check-in: [5358e9ea6a] user: js, branch: trunk, size: 19860 [annotate] [blame] [check-ins using] [diff]

This is more compatible with the various conventions used on various
systems. file: [fae3aff94d] check-in: [79fe29dbf4] user: js, branch: trunk, size: 19864 [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: [3d1d7d2d6b] check-in: [ef6d69931e] user: js, branch: trunk, size: 19857 [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: [2ef4db4bbd] check-in: [482698c5be] user: js, branch: trunk, size: 20010 [annotate] [blame] [check-ins using] [diff]

This removes the special casing for Itanium and makes compilation on
OpenBSD/SPARC64 work with clang. file: [dc5760d5ce] check-in: [879e69dd3d] user: js, branch: trunk, size: 19891 [annotate] [blame] [check-ins using] [diff]

This also renames ObjFW-RT to ObjFW_RT, as hyphens should not be in
framework names. file: [2f76cd89bc] check-in: [0f42b0eafd] user: js, branch: trunk, size: 19781 [annotate] [blame] [check-ins using] [diff]

DW_EH_PE_datarel can be handled via _Unwind_GetGR on GR 1, while
DW_EH_PE_textrel cannot be handled at all. file: [ba1f5e6f08] check-in: [60ce701c5c] user: js, branch: trunk, size: 19758 [annotate] [blame] [check-ins using] [diff]

Casts are now written like types in variable declarations. file: [9516bed461] check-in: [4af49a13c3] user: js, branch: trunk, size: 19582 [annotate] [blame] [check-ins using] [diff]

Forgot to add 2017, even though I already did quite some changes in
2017. file: [59e66d5415] check-in: [44f45c2e35] user: js, branch: trunk, size: 17321 [annotate] [blame] [check-ins using] [diff]

This allows handling C++ exceptions. file: [438f4d8af0] check-in: [974d386554] user: js, branch: trunk, size: 17318 [annotate] [blame] [check-ins using] [diff]

Use OBJC_ERROR() to print an error message instead of silently aborting. file: [30cec995ef] check-in: [85a52c4717] user: js, branch: trunk, size: 16342 [annotate] [blame] [check-ins using] [diff]

No functional change. file: [9ee77747e2] check-in: [b919654740] user: js, branch: trunk, size: 16040 [annotate] [blame] [check-ins using] [diff]

While at it, also update the mail address. file: [e01b920560] check-in: [cec0f072f8] user: js, branch: 0.8, size: 15988 [annotate] [blame] [check-ins using] [diff]

While at it, also update the mail address. file: [f01e2fc526] check-in: [2a27cf3000] user: js, branch: trunk, size: 15788 [annotate] [blame] [check-ins using] [diff]

No functional change intended. file: [bf6c15d416] check-in: [9da9b2b64c] user: js, branch: trunk, size: 15923 [annotate] [blame] [check-ins using] [diff]

This also gets rid of RAISE_EXCEPTION and instead defines
_Unwind_RaiseException to _Unwind_SjLj_RaiseException for SjLj.

Additionally, it moves the defines to the top of the file. file: [c587b3ed95] check-in: [65a0124f8d] user: js, branch: trunk, size: 15918 [annotate] [blame] [check-ins using] [diff]

Does not work yet due to a GCC bug. I already found the bug and also
have a fix for it, but it needs to get upstreamed. file: [02a3674deb] check-in: [d7883de826] user: js, branch: trunk, size: 16083 [annotate] [blame] [check-ins using] [diff]

This caused the landingpad to be 0 on MIPS/N32. file: [d295243776] check-in: [a655ba9020] user: js, branch: trunk, size: 15251 [annotate] [blame] [check-ins using] [diff]

It seems that this call is fine with Clang, but crashes with GCC.
Removing this call does not seem to introduce a leak (verified with
valgrind). file: [8bf5e39212] check-in: [6dcd43ed6c] user: js, branch: trunk, size: 15217 [annotate] [blame] [check-ins using] [diff]

The only places where BOOL is left are those where they are required by
the ABI. file: [33f7be3a9f] check-in: [c5ef582958] user: js, branch: trunk, size: 14384 [annotate] [blame] [check-ins using] [diff]

m68k seems to use an empty class name instead of NULL. file: [375c6e97c6] check-in: [ebaf70c292] user: js, branch: trunk, size: 14372 [annotate] [blame] [check-ins using] [diff]

This makes it easier to use runtime functions in portable code. file: [d52bb65783] check-in: [120caad331] user: js, branch: trunk, size: 14280 [annotate] [blame] [check-ins using] [diff]

This partly reverts 93dad6d, as it did fix ARC + -fobjc-arc-exceptions
with Clang, but broke exceptions in general with GCC. file: [ef3f114f24] check-in: [aecc08c367] user: js, branch: trunk, size: 14250 [annotate] [blame] [check-ins using] [diff]

There still seems to be an issue with Clang on 32 bit systems, but it
works with GCC now. file: [467b03e18b] check-in: [ce6282e019] user: js, branch: trunk, size: 11377 [annotate] [blame] [check-ins using] [diff]
