0 | 1 1.0: |
2 ---- | |
86 | 3 - the CallVM-free functions are per VTable, however the latter can be changed out |
4 at runtime... which basically changes potentially the deallocator... | |
5 same goes for functions setting the mode. think about how to make this safer - currently | |
6 we have a higher flexibility and we need to potentially clean up from the mode we are in, | |
7 however, this is open to misuse | |
78 | 8 - check all vararg calling conv implementations if they promote correctly |
9 (e.g. float to double); we used to not care as it was the user's job to | |
10 think of that, but we allow users to use ArgFloat, etc. on "..." now, | |
11 taking care of the promotion; so it should be consistent all across the | |
12 implementations -> also write testcode specifically for that | |
0 | 13 - autovar was never really pushed all the way through and still plays second |
9 | 14 fiddle to dyncall_macros.h, clean this all up, eventually (Tassilo: for now, I |
15 removed out of sync files to avoid confusion; but still probably duped code) | |
0 | 16 - ppc32 callback fixes on bsd |
69 | 17 - add portable "make install" |
18 * make install should also install manpages | |
0 | 19 - mailing list announcements (html email?) |
20 - fix for NDS: | |

26 - callback_plain retval, see above under ARM |
69 | 27 - callf |
24 | 28 - support Solaris11 CFLAGS with -D_FILE_OFFSET_BITS=64 |
29 - make sure selinux works (esp. regarding NX bits, asm might need (or similar): .section .note.GNU-stack,"",@progbits) | |
54 | 30 Daniel has a patch for it, if needed, implementing allocwx with two memory blocks, one for w^x, mmaped to one for r|x |
68 | 31 - support /SAFESEH on cl/win32 |

48 - dyncall_call_mips_n32.h and dyncall_call_mips_n64.h are pretty much the same, share code |
0 | 49 - support for return values: aggregate return values |
50 - support for argument values: structures, half-precision, vector types, long double | |
51 - consider automatic type-promotion for arguments passed through DC_CALL_C_ELLIPSIS_VARARGS; | |
52 this would make it easier to just pass arguments instead of having to know about the C | |
88 | 53 type promotions (this is partly done, see todo-item above under 1.0) |
0 | 54 - syscalls for x64 |
55 * bsd | |
56 * linux | |
57 - other syscalls | |
110 | 58 - MIPS32 softfloat support (-msoft-float) |
135 | 59 - test MIPS32 eabi big endian (current port works on psp, which is little endian) |

69 dynload: | |
70 -------- | |
71 - bug: test/nm crashes on qemu mips linux o32 debian etch | |
72 - test/resolve_self crashes/asserts on windows and bsds | |
73 - rename SymsInit to InitSyms and similar for cleanup function to reflect naming | |
74 in dyncall | |
75 - get rid of Dl_info and friends (_GNU_SOURCE) in dynload/dynload_syms_elf.c | |
76 for implementation of dlSymsNameFromValue(..) | |
77 - check if PSP can support dynload (missing elf.h, dlfcn.h, etc.); fixup readme if successful | |
84 | 78 - some functionality like java's System.mapLibraryName('name') might be helpful? |

94 bindings: | |
95 --------- | |
96 - release bindings as standalone packages (already done for rbdc as a gem and rdyncall on cran) | |
97 * add note to documentation, where bindings are and that some bindings are svn-only ATM | |
98 - add rdoc documentation to ruby gem | |
99 - add pydoc for python | |
100 - add manpage for shdc | |
101 - expose callf-convenience functions to go | |
102 - add godoc for godc | |

114 problems with multirow.4ht) |
0 | 115 - provide more examples on how to use dyncall, dynload and dyncallback |
116 * e.g. enhance manual with a couple of examples (e.g. calling MessageBoxA on windows, etc.) | |
117 - manuals for bindings (as stated in bindings-section, above) | |
117 | 118 - under "dyncall support", in each calling convention appendix, list crucial details of e.g. big/little endian support, etc. |
119 - specify integer models in use, use common ILP32, LLP64, etc. terms | |
0 | 120 |
88 | 121 regressions: |
122 ------------ | |
0 | 123 - finish SPARC/SPARC64 calling conventions in doc's callconv-appendix !!! |
124 - Haiku/gmake build doesn't build dynload due to the fact, that elf.h is not found | |
125 on default installations (one has to install the system headers) | |
126 * add to doc | |
127 - Solaris/gmake build doesn't build dynload and tests anymore (maybe not even dyncallback) | |
128 - test arm32/ATPCS/THUMB (and then change Status in doc Appendix) | |
129 - look over code and fix TODO or @@@ marks | |
130 - add ppc-support to doc (both, 32 and 64, as well as little and big endian remarks) | |
131 | |
132 nice to have: | |
133 ------------- | |
134 - update: microsoft visual c++ build files - integrate all test suites in solution file | |
135 - consistency: on x64 platforms: make both ABIs available ('win64','sysv') for all x64 OS ports | |
136 - microsoft build enhancement: autodetect assembly via C preprocessor (like with .S gcc files) | |
137 - test/thunk: some platforms do not allow for allocation of executable code on heap and stack -- | |
138 currently this test will crash, maybe we should collect information which platforms allow and which not. | |
139 | |
140 bugs: | |
141 ----- | |
88 | 142 - setting callconv, specifically for platforms that have only one (default)) excepts on some |
6 | 143 platforms, eg. setting X64_sysv on amd64/Linux - keeping cdecl which is the same in |
88 | 144 this case, works (this should work now...) |
0 | 145 - vararg function calls don't work for ARM THUMB mode (Daniel's new interface for modesetting for varag |
146 args should be used); adapt test/ellipsis and/or retest | |
147 | |
