Hugo Melder	ab23f14fd7	Initial Windows on ARM (AArch64) Support (#249 ) * Conditionally include ntdll.dll * Use text relocation instead of GOT * Use FlushInstructionCache instead of clear_cache for arm64 * Load address in two stages (adrp, add) * objc_msgSend.aarch64.S add comments * Add seh directives * Move .seh_proc into slow sloop section * Comment out cfi directives * Substitute raw .seh directives with macros * Add documentation of SEH annotations * Detect CPU Architecture with preprocessor * Cleanup CMakeLists.txt Co-authored-by: David Chisnall <davidchisnall@users.noreply.github.com> * Remove line in objc_msgSend.aarch64.S Co-authored-by: David Chisnall <davidchisnall@users.noreply.github.com> * Change Test CMakeList to use ARCHITECTURE var * Use existing clear cache macro * Change _WIN64 to _WIN32 and reorder labels * Remove macro and replace _WIN64 with _WIN32 * Remove argument from non-win32 macro --------- Co-authored-by: David Chisnall <davidchisnall@users.noreply.github.com>	2 years ago
Niels Grewe	0e84e318e7	Use (anonymous) mmap() when available. Should fix #147 (SELinux related segfault)	6 years ago
Frederik Seiffert	d16faeded9	Fixed warning in imp_implementationWithBlock. This was caused by switching the method signature to use "id" for the block parameter.	7 years ago
Frederik Seiffert	a2463192d0	Use `id` as type for block runtime functions. Fixes #103.	7 years ago
Frederik Seiffert	f4b381febb	Replace valloc() with posix_memalign(). valloc() no longer exists in some toolchains like Android arm64.	7 years ago
David Chisnall	1bc7ac26f8	Improve block-to-IMP code on Windows. This version will work with Windows Store apps. Patch by Dustin Howett!	8 years ago
David Chisnall	934cd13a7a	Initial pass at Windows support. All tests now pass with the new ABI on x86-64, with the new ABI. Some of the code is ugly and other platforms are probably broken.	8 years ago
David Chisnall	4ab78aa49a	Check for Thumb-2 more explicitly.	10 years ago
David Chisnall	c8848614b5	Now that we’re not marking the block trampoline functions as functions, the start and end symbols will appear as normal data pointers with no Thumb mangling, so remove the code that unmangles them.	10 years ago
David Chisnall	9e51aabc98	Fix block trampolines to work when mixed with Thumb-2 code.	10 years ago
David Chisnall	ef458104dd	Remove some debugging code.	10 years ago
David Chisnall	1933167046	Copy (retain) blocks when they are used as IMPs.	10 years ago
David Chisnall	e8604511a6	Fix block metadata address calculation.	10 years ago
David Chisnall	77df8d3d92	Remove debugging line.	10 years ago
David Chisnall	7eeffe9d09	Rewrite the block-to-imp code so that: - We reuse the memory allocated for blocks - We no longer have the same physical page mapped write and execute	10 years ago
ivucica	4742f71d29	Added #define __has_builtin into block_to_imp.c.	12 years ago
theraven	dc241dc1bf	Make sure that we flush the instruction cache when creating a new IMP at run time.	12 years ago
theraven	6394126bfe	Some cleanups in block to IMP conversion. On FreeBSD (and other platforms that choose to implement the , allocate the memory via the anonymous shared memory mechanism, removing the need for the temporary file. On other POSIX platforms, correctly use mkstemp().	12 years ago
theraven	8baefbe5c8	Expose asprintf() with glibc.	13 years ago
thebeing	f845df37c1	Add objc/blocks_private.h header to expose some internals of the blocks runtime that are accessed by libdispatch. Also rename the relevant structs to be compatible with the BlocksRuntime from compiler-rt.	14 years ago
thebeing	e8645c8ceb	Small QNX compatibility tweak.	14 years ago
theraven	f9f2e4e313	Added a function for getting the type encoding for a block returned by imp_implementationFromBlock().	14 years ago
theraven	43ee8b9819	Add initial support for imp_implementationWithBlock() and friends. Currently only works on x86 and x86-64 and doesn't work with sret functions.	14 years ago
