 1.1:
 ----
-- plain_cpp only supports windows; fix
+- test code: add sparc tests for when out of register windows, meaning multiple layers deep in the call stack
 - ./configure on macOS does not pass CFLAGS etc.. to Makefile.config
 - support platforms without shared libraries so they can be built by just typing `./configure;make` (e.g. minix < 3.2.1)
 * 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)
 - dyncall supports calls to functions where prototype exists (with and without varargs); however not when no
 prototype exist (e.g. just calling some pointer), without any declaration... even possible in C, as one has
 to cast to the function type? need to support?
 - dyncallback's "stack_cleanup" can be removed from non x86 impls... test if they still work
 - target a minimum c version, for use with -pedantic, etc.? Right now we use e.g. extensions
-for anon structs, etc.
+for anon structs, etc. -> we do now target c99
 - 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
 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:
 - 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
+- add tests using alloca(), as this might depend on the frame pointer being correctly set (we don't
-set; we don't check for this, currently, at all
+check for this, currently, at all - but might not affect dyncall's stubs, anyways) - verify
 portasm:
 --------
 - add solaris support for x64
 * test return values
 * convert from c++ to c, to have it also on plan9, and more portability
 dynload:
 --------
-- RTLD_LAZY in darwin, why not in unix?
 - dlGetLibraryPath: dl_iterate_phdr() used on OpenBSD, but not available on version < 3.7
 - 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
 dyncallback:
 ------------
 - callback_plain's return value not correct anymore on NDS (maybe just broken testcode?),
 see above under 1.1 items
 * check other platforms also, if asm stub initializes retval space, correctly
-- finish PPC32 callbacks (see bugs section, below, BSD not working)
 - test MIPS32 eabi big endian (current port works on psp, which is little 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)
 - MIPS64 n32 softfloat support (-msoft-float)
 - implement MIPS64 EABI (gcc -mabi=eabi); both, little and big-endian
 - add call-conv-mode-support for rbdc through signature
 manual:
 -------
 - 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
+* 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
 - 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)
-- 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
 ------------
 - 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.
+currently this test will segfault (handled), maybe we should collect information which platforms allow and which not.
+- PSP
+	- automate ppsspp stuff, seems to print to stdout for callback_suite? but not for call_suite.. (?)
+	- fix link with dummy versions of the following for test-bins:
+		void __stack_chk_fail(){}
+		void __stack_chk_guard(){}
 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
