| 355 | 1 1.2: |
| 0 | 2 ---- |
| 355 | 3 - openbsd-4.0-* test/resolve_self fails, but unsure why. dlopen correctly returns RTLD_DEFAULT, which |
| 4 should lookup via dlsym the function in the object itself, but cannot. So... some compiler flag might | |
| 5 be missing to keep symbol names, or some prefixing happens | |
| 6 - dyncall/dyncall_call*h could probably be all removed, as forward declarations in corresponding .c | |
| 7 files would be enough; no headers are needed b/c those functions declared in there are of no public use | |
| 8 - test/thunk win/x64 doesn't output anything decent for stack test (neither sigsegv nor output), which can create a problem for test log file as it'll mess with the subsequent test's output) | |
| 9 - remove test/gen-masm alltogether | |
| 329 | 10 - test code: add sparc tests for when out of register windows, meaning multiple layers deep in the call stack |
| 286 | 11 - ./configure on macOS does not pass CFLAGS etc.. to Makefile.config |
|

- added to configure some detection on how to compile .s/.S with --noexecstack (or similar), as compilers' defaults are often insane

12 - support platforms without shared libraries so they can be built by just typing `./configure;make` (e.g. minix < 3.2.1) |

13 * 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 | 14 - dyncall supports calls to functions where prototype exists (with and without varargs); however not when no |
| 15 prototype exist (e.g. just calling some pointer), without any declaration... even possible in C, as one has | |
| 16 to cast to the function type? need to support? | |

20 - target a minimum c version, for use with -pedantic, etc.? Right now we use e.g. extensions |
| 329 | 21 for anon structs, etc. -> we do now target c99 |
| 86 | 22 - the CallVM-free functions are per VTable, however the latter can be changed out |
| 23 at runtime... which basically changes potentially the deallocator... | |
| 24 same goes for functions setting the mode. think about how to make this safer - currently | |
| 25 we have a higher flexibility and we need to potentially clean up from the mode we are in, | |
| 26 however, this is open to misuse | |
| 78 | 27 - check all vararg calling conv implementations if they promote correctly |
| 28 (e.g. float to double); we used to not care as it was the user's job to | |
| 29 think of that, but we allow users to use ArgFloat, etc. on "..." now, | |
| 30 taking care of the promotion; so it should be consistent all across the | |
| 31 implementations -> also write testcode specifically for that | |
| 0 | 32 - autovar was never really pushed all the way through and still plays second |
| 9 | 33 fiddle to dyncall_macros.h, clean this all up, eventually (Tassilo: for now, I |
| 34 removed out of sync files to avoid confusion; but still probably duped code) | |
| 69 | 35 - add portable "make install" |
| 36 * make install should also install manpages | |
| 0 | 37 - mailing list announcements (html email?) |
| 38 - fix for NDS: | |
| 69 | 39 * ARM: |

52 - pkg-config support? |
| 90 | 53 - quadmath support (long double) |
| 329 | 54 - add tests using alloca(), as this might depend on the frame pointer being correctly set (we don't |
| 55 check for this, currently, at all - but might not affect dyncall's stubs, anyways) - verify | |
| 0 | 56 |

| 60 | |
| 61 dyncall: | |
| 62 -------- | |
| 288 | 63 - merge arm32_thumb_{gas/apple} and include thumb support for portasm |

67 - dyncall_call_mips_n32.h and dyncall_call_mips_n64.h are pretty much the same, share code |
| 0 | 68 - support for return values: aggregate return values |
| 69 - support for argument values: structures, half-precision, vector types, long double | |
| 288 | 70 * make sure that struct support for ellipsis calls are not forgotten (copy everything by value) |
| 0 | 71 - consider automatic type-promotion for arguments passed through DC_CALL_C_ELLIPSIS_VARARGS; |
| 72 this would make it easier to just pass arguments instead of having to know about the C | |
| 278 | 73 type promotions (this is partly done, see todo-item above under 1.1) |
| 0 | 74 - other syscalls |

| 86 dynload: | |
| 87 -------- | |
| 244 | 88 - dlGetLibraryPath: dl_iterate_phdr() used on OpenBSD, but not available on version < 3.7 |
| 0 | 89 - bug: test/nm crashes on qemu mips linux o32 debian etch |
| 90 - rename SymsInit to InitSyms and similar for cleanup function to reflect naming | |
| 91 in dyncall | |
| 92 - get rid of Dl_info and friends (_GNU_SOURCE) in dynload/dynload_syms_elf.c | |
| 93 for implementation of dlSymsNameFromValue(..) | |
| 94 - check if PSP can support dynload (missing elf.h, dlfcn.h, etc.); fixup readme if successful | |

119 - MIPS64 n32 softfloat support (-msoft-float) |
| 129 | 120 - implement MIPS64 EABI (gcc -mabi=eabi); both, little and big-endian |
| 141 | 121 - support for Minix/arm |
| 0 | 122 |
| 123 bindings: | |
| 124 --------- | |
| 125 - release bindings as standalone packages (already done for rbdc as a gem and rdyncall on cran) | |
| 126 * add note to documentation, where bindings are and that some bindings are svn-only ATM | |
| 127 - add rdoc documentation to ruby gem | |
| 128 - add pydoc for python | |
| 129 - add manpage for shdc | |
| 130 - expose callf-convenience functions to go | |
| 131 - add godoc for godc | |
| 132 - add javadoc to java | |
| 133 - add more bindings | |
| 134 - add callback support for erlang, go, java, lua, python and ruby (and shell? how?) | |
| 135 - add call-conv-mode-support for rbdc through signature | |
| 136 | |
| 137 manual: | |
| 138 ------- | |
| 201 | 139 - introduce doc overview tables and common vocab for calling convention specifics, following example of table on page 13 of https://www.linux-mips.org/pub/linux/mips/doc/ABI/MIPS-N32-ABI-Handbook.pdf; also as inspiration, e.g. user 'preserved' instead of 'permanent', etc. https://developer.apple.com/library/content/documentation/Xcode/Conceptual/iPhoneOSABIReference/Articles/ARMv6FunctionCallingConventions.html#//apple_ref/doc/uid/TP40009021-SW4 |
| 329 | 140 * also, get inspiration for naming for GCC predefs as talked about in https://stffrdhrn.github.io/software/embedded/openrisc/2018/06/08/gcc_stack_frames.html |
| 201 | 141 - 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) |
| 332 | 142 * another example, chapter 3 of: ftp://www.sourceware.org/pub/binutils/ppc-docs/ppc-poweropen/ |
| 0 | 143 - provide more examples on how to use dyncall, dynload and dyncallback |
| 144 * e.g. enhance manual with a couple of examples (e.g. calling MessageBoxA on windows, etc.) | |
| 145 - manuals for bindings (as stated in bindings-section, above) | |
| 117 | 146 - under "dyncall support", in each calling convention appendix, list crucial details of e.g. big/little endian support, etc. |
| 147 - specify integer models in use, use common ILP32, LLP64, etc. terms | |
| 0 | 148 |
| 88 | 149 regressions: |
| 150 ------------ | |
| 0 | 151 - Haiku/gmake build doesn't build dynload due to the fact, that elf.h is not found |
| 152 on default installations (one has to install the system headers) | |
| 153 * add to doc | |
| 154 - Solaris/gmake build doesn't build dynload and tests anymore (maybe not even dyncallback) | |
| 155 - look over code and fix TODO or @@@ marks | |
| 156 - add ppc-support to doc (both, 32 and 64, as well as little and big endian remarks) | |
| 157 | |
| 158 nice to have: | |
| 159 ------------- | |
| 160 - update: microsoft visual c++ build files - integrate all test suites in solution file | |
| 161 - consistency: on x64 platforms: make both ABIs available ('win64','sysv') for all x64 OS ports | |
| 162 - microsoft build enhancement: autodetect assembly via C preprocessor (like with .S gcc files) | |
| 163 - test/thunk: some platforms do not allow for allocation of executable code on heap and stack -- | |
| 329 | 164 currently this test will segfault (handled), maybe we should collect information which platforms allow and which not. |
| 165 - PSP | |
| 166 - automate ppsspp stuff, seems to print to stdout for callback_suite? but not for call_suite.. (?) | |
| 167 - fix link with dummy versions of the following for test-bins: | |
| 168 void __stack_chk_fail(){} | |
| 169 void __stack_chk_guard(){} | |
| 0 | 170 |
| 171 bugs: | |
| 172 ----- | |
| 88 | 173 - setting callconv, specifically for platforms that have only one (default)) excepts on some |
| 6 | 174 platforms, eg. setting X64_sysv on amd64/Linux - keeping cdecl which is the same in |
| 88 | 175 this case, works (this should work now...) |
| 0 | 176 - vararg function calls don't work for ARM THUMB mode (Daniel's new interface for modesetting for varag |
| 177 args should be used); adapt test/ellipsis and/or retest | |
| 178 | |
