1.0: ---- - the CallVM-free functions are per VTable, however the latter can be changed out at runtime... which basically changes potentially the deallocator... same goes for functions setting the mode. think about how to make this safer - currently we have a higher flexibility and we need to potentially clean up from the mode we are in, however, this is open to misuse - check all vararg calling conv implementations if they promote correctly (e.g. float to double); we used to not care as it was the user's job to think of that, but we allow users to use ArgFloat, etc. on "..." now, taking care of the promotion; so it should be consistent all across the implementations -> also write testcode specifically for that - autovar was never really pushed all the way through and still plays second fiddle to dyncall_macros.h, clean this all up, eventually (Tassilo: for now, I removed out of sync files to avoid confusion; but still probably duped code) - ppc32 callback fixes on bsd - add portable "make install" * make install should also install manpages - mailing list announcements (html email?) - fix for NDS: * ARM: - callback_plain retval wrong (not only platform), area on stack where it's stored is probably not zeroed, so half-words, etc., come with garbage * THUMB: - ellipsis (might be test itself, not respecting fixed part of args) - callback_plain retval, see above under ARM - callf - fix Minix/x86 callbacks (see callback_suite) - armhf ellipsis: fix weirdness with long long as first ... arg - support Solaris11 CFLAGS with -D_FILE_OFFSET_BITS=64 - make sure selinux works (esp. regarding NX bits, asm might need (or similar): .section .note.GNU-stack,"",@progbits) Daniel has a patch for it, if needed, implementing allocwx with two memory blocks, one for w^x, mmaped to one for r|x - support /SAFESEH on cl/win32 - test code functions should be in .so files, optionally, so the suites can directly be used to test dycnall bindings - pkg-config support? - quadmath support (long double) - add tests using alloca(), as this might depend on the frame pointer being correctly set; we don't check for this, currently, at all portasm: -------- - add solaris support for x64 dyncall: -------- - support for return values: aggregate return values - support for argument values: structures, half-precision, vector types, long double - varargs for mips (might exist, but test all ABIs (mipseb n64 already confirmed)) - consider automatic type-promotion for arguments passed through DC_CALL_C_ELLIPSIS_VARARGS; this would make it easier to just pass arguments instead of having to know about the C type promotions (this is partly done, see todo-item above under 1.0) - syscalls for x64 * bsd * linux - other syscalls - MIPS32 softfloat support (-msoft-float) - MIPS64 little-endian needs testing (current port works on openbsd/octeon, which is big endian) - implement MIPS64 N32 (gcc -mabi=n32); both, little and big-endian (looks like NetNBSD on and EdgeRouter lite uses this: https://blog.netbsd.org/tnf/entry/hands_on_experience_with_edgerouter) - implement MIPS64 EABI (gcc -mabi=eabi); both, little and big-endian dynload: -------- - bug: test/nm crashes on qemu mips linux o32 debian etch - test/resolve_self crashes/asserts on windows and bsds - rename SymsInit to InitSyms and similar for cleanup function to reflect naming in dyncall - get rid of Dl_info and friends (_GNU_SOURCE) in dynload/dynload_syms_elf.c for implementation of dlSymsNameFromValue(..) - check if PSP can support dynload (missing elf.h, dlfcn.h, etc.); fixup readme if successful - some functionality like java's System.mapLibraryName('name') might be helpful? dyncallback: ------------ - add SPARC and SPARC64 callback support - callback_plain's return value not correct anymore on NDS (maybe just broken testcode?), see above under 1.0 items * check other platforms also, if asm stub initializes retval space, correctly - finish PPC32 callbacks (see bugs section, below, BSD not working) - MIPS32 softfloat support (-msoft-float) - test MIPS o32 big endian (current port works on netbsd/pmax, which is little endian, and gcc -EB doesn't work on there) - test MIPS n64 little endian (current port works on openbsd/octeon, which is big endian) - implement MIPS64 N32 (gcc -mabi=n32); both, little and big-endian (looks like NetNBSD on and EdgeRouter lite uses this: https://blog.netbsd.org/tnf/entry/hands_on_experience_with_edgerouter) - implement MIPS64 EABI (gcc -mabi=eabi); both, little and big-endian bindings: --------- - release bindings as standalone packages (already done for rbdc as a gem and rdyncall on cran) * add note to documentation, where bindings are and that some bindings are svn-only ATM - add rdoc documentation to ruby gem - add pydoc for python - add manpage for shdc - expose callf-convenience functions to go - add godoc for godc - add javadoc to java - add more bindings - add callback support for erlang, go, java, lua, python and ruby (and shell? how?) - add call-conv-mode-support for rbdc through signature manual: ------- - callconv diagrams: * good idea to review it all, anyways, if the calling conventions are actually represented correctly (and if they are in sync with the .pdf, we used to have problems with multirow.4ht) - provide more examples on how to use dyncall, dynload and dyncallback * e.g. enhance manual with a couple of examples (e.g. calling MessageBoxA on windows, etc.) - manuals for bindings (as stated in bindings-section, above) - under "dyncall support", in each calling convention appendix, list crucial details of e.g. big/little endian support, etc. - specify integer models in use, use common ILP32, LLP64, etc. terms regressions: ------------ - finish SPARC/SPARC64 calling conventions in doc's callconv-appendix !!! - Haiku/gmake build doesn't build dynload due to the fact, that elf.h is not found on default installations (one has to install the system headers) * add to doc - Solaris/gmake build doesn't build dynload and tests anymore (maybe not even dyncallback) - test arm32/ATPCS/THUMB (and then change Status in doc Appendix) - look over code and fix TODO or @@@ marks - add ppc-support to doc (both, 32 and 64, as well as little and big endian remarks) nice to have: ------------- - update: microsoft visual c++ build files - integrate all test suites in solution file - consistency: on x64 platforms: make both ABIs available ('win64','sysv') for all x64 OS ports - microsoft build enhancement: autodetect assembly via C preprocessor (like with .S gcc files) - test/thunk: some platforms do not allow for allocation of executable code on heap and stack -- currently this test will crash, maybe we should collect information which platforms allow and which not. bugs: ----- - setting callconv, specifically for platforms that have only one (default)) excepts on some platforms, eg. setting X64_sysv on amd64/Linux - keeping cdecl which is the same in this case, works (this should work now...) - vararg function calls don't work for ARM THUMB mode (Daniel's new interface for modesetting for varag args should be used); adapt test/ellipsis and/or retest missing implementations (descending priority): ---------------------------------------------- - riscv - itanium - superh/j-core - 68k, 88k, 6502, etc. - arc - alpha - cell - blackfin - seaforth - s/390 - z80 - hppa - vax - atmel avr - propeller - amd29k
