5 * also make sure minix with shared library support builds and works in general (>= 3.2.1) as well as ELF on Minix (>= 3.2.0) to begin with (as that's the base, and we only test on 3.1.8 so far) |
| 201 | 6 - dyncall supports calls to functions where prototype exists (with and without varargs); however not when no |
| 7 prototype exist (e.g. just calling some pointer), without any declaration... even possible in C, as one has | |
| 8 to cast to the function type? need to support? | |

13 for anon structs, etc. |
| 86 | 14 - the CallVM-free functions are per VTable, however the latter can be changed out |
| 15 at runtime... which basically changes potentially the deallocator... | |
| 16 same goes for functions setting the mode. think about how to make this safer - currently | |
| 17 we have a higher flexibility and we need to potentially clean up from the mode we are in, | |
| 18 however, this is open to misuse | |
| 78 | 19 - check all vararg calling conv implementations if they promote correctly |
| 20 (e.g. float to double); we used to not care as it was the user's job to | |
| 21 think of that, but we allow users to use ArgFloat, etc. on "..." now, | |
| 22 taking care of the promotion; so it should be consistent all across the | |
| 23 implementations -> also write testcode specifically for that | |
| 0 | 24 - autovar was never really pushed all the way through and still plays second |
| 9 | 25 fiddle to dyncall_macros.h, clean this all up, eventually (Tassilo: for now, I |
| 26 removed out of sync files to avoid confusion; but still probably duped code) | |
| 69 | 27 - add portable "make install" |
| 28 * make install should also install manpages | |
| 0 | 29 - mailing list announcements (html email?) |
| 30 - fix for NDS: | |

57 - dyncall_call_mips_n32.h and dyncall_call_mips_n64.h are pretty much the same, share code |
| 0 | 58 - support for return values: aggregate return values |
| 59 - support for argument values: structures, half-precision, vector types, long double | |
| 60 - consider automatic type-promotion for arguments passed through DC_CALL_C_ELLIPSIS_VARARGS; | |
| 61 this would make it easier to just pass arguments instead of having to know about the C | |
| 278 | 62 type promotions (this is partly done, see todo-item above under 1.1) |

| 120 - make stack layout diagrams better, e.g. add grow direction (example: https://developer.apple.com/library/content/documentation/Xcode/Conceptual/iPhoneOSABIReference/art/arm_stack.jpg on https://developer.apple.com/library/content/documentation/Xcode/Conceptual/iPhoneOSABIReference/Articles/ARMv6FunctionCallingConventions.html#//apple_ref/doc/uid/TP40009021-SW1) | |

124 problems with multirow.4ht) |
| 0 | 125 - provide more examples on how to use dyncall, dynload and dyncallback |
| 126 * e.g. enhance manual with a couple of examples (e.g. calling MessageBoxA on windows, etc.) | |
| 127 - manuals for bindings (as stated in bindings-section, above) | |
| 117 | 128 - under "dyncall support", in each calling convention appendix, list crucial details of e.g. big/little endian support, etc. |
| 129 - specify integer models in use, use common ILP32, LLP64, etc. terms | |
| 0 | 130 |
| 88 | 131 regressions: |
| 132 ------------ | |
| 0 | 133 - Haiku/gmake build doesn't build dynload due to the fact, that elf.h is not found |
| 134 on default installations (one has to install the system headers) | |
| 135 * add to doc | |
| 136 - Solaris/gmake build doesn't build dynload and tests anymore (maybe not even dyncallback) | |
| 137 - test arm32/ATPCS/THUMB (and then change Status in doc Appendix) | |
| 138 - look over code and fix TODO or @@@ marks | |
| 139 - add ppc-support to doc (both, 32 and 64, as well as little and big endian remarks) | |
| 140 | |
| 141 nice to have: | |
| 142 ------------- | |
| 143 - update: microsoft visual c++ build files - integrate all test suites in solution file | |
| 144 - consistency: on x64 platforms: make both ABIs available ('win64','sysv') for all x64 OS ports | |
| 145 - microsoft build enhancement: autodetect assembly via C preprocessor (like with .S gcc files) | |
| 146 - test/thunk: some platforms do not allow for allocation of executable code on heap and stack -- | |
| 147 currently this test will crash, maybe we should collect information which platforms allow and which not. | |
| 148 | |
| 149 bugs: | |
| 150 ----- | |
| 88 | 151 - setting callconv, specifically for platforms that have only one (default)) excepts on some |
| 6 | 152 platforms, eg. setting X64_sysv on amd64/Linux - keeping cdecl which is the same in |
| 88 | 153 this case, works (this should work now...) |
| 0 | 154 - vararg function calls don't work for ARM THUMB mode (Daniel's new interface for modesetting for varag |
| 155 args should be used); adapt test/ellipsis and/or retest | |
