besta-tools's Issues

Dynamic linking

BPABI should allow converting AAELF shared objects to user format DLLs. Figure out how so we can generate DLLs and import tables.

Handle relative RELs

Some features such as exceptions depend on those.

Use section flag-based conversion instead of segment-based

Segment-based conversion assumes the segment structure of the ELF/the ldscript used to generate such ELF, which is not very generic and only works with the custom ldscript that was part of the old devkitPro-based toolchain. It should instead use section flags (or maybe segment flags?) to decide what ELF segments to map to what PE section and use segment info to ensure these sections are contiguous and within the appropriate segments.

Note that the old ldscript behavior may be simulated by passing the ldflags -Wl,-z,max-page-size=0x1000,-z,separate-code on the new toolchain or any other arm-none-eabi toolchains with GCC's default ldscript.

Consider silencing "Byte 0x00 makes up x% of the file's contents" warning

It's useless when the file is just a couple of pages long and it will be guaranteed to trip.

Better way is to check the # of ELF pages (which will be turned into PE pages) and inhibit this warning if page count is extremely low.

Is it possible to build a custom PRIME_APP.DAT with your tools?

Your project looks like very promising, I'd be very interested to know if it is possible to build KhiCAS for the Prime G1 using your tools, like ExistOS does for the hp39gii.
This would bring up some welcome enhancements on the G1 wrt the builtin CAS including:

• up to date Giac/Xcas version with all commands available
• inclusion of LGPL-ed libraries: GMP, MPFR, MPFI: faster bigint support, bigfloat library with arbitrary number of digits computation, interval arithmetic
• programming editor and shell with syntax coloration, parenthese match
• 3d geometry app
• javascript support
  That way the Prime G1 would match other ports of KhiCAS on the Casio fxcg50, Numworks N0110/N0115/N0120 and TI Nspire.
