TODO

# Major things
- floating-point support
- multi-word integer arithmetic (eg. uint64_t on 32bit arch)
- passing & returning structs in function calls


# Linking support
- support for building shared libraries


# libbcc
- crtbegin.o, crtend.o
- libbcc.a
- riscv32: software multiply seems broken


# Language
- proper switch/case
- allow support for old C-style (function) pointers
- add configure option to disable extensions
- add support for strings containing '\0' values
- implement constant propagation
- <stdarg.h> header
- long long & long double
- <stdint.h>: UINTN_C()


# IR-generation
- more advanced optimization techniques
- fix remove_unreferenced() for function call arguments


# Architecture-specific related
General:
- replace `builtin functions` with `inlinable intrinsics`

x86:
- optimize function calls
- add VLAs back

riscv:
- more simple optimizations
- add VLAs
- check detect_sys.sh on real hardware

arm:
- Support for big-endian
- Add support for aarch64/armv8+
- Add VLAs

# Pre-processor
- create a test-suite
- more test cases for macro expansion
- support for variadic macros
- #pragma


# Test suite


# Known bugs
- not working test cases:
   - 'arraylen(VLA)'
   - 'sizeof(VLA)'
   - 'return struct'
   - 'pass struct'
- multi-core `make` may be broken

# Documentation
- update and finish the manual
- add comments describing the code
- add a guide on how to port this project to a new arch


# Other
- options: -g, --sysroot=
- add zsh-completions
- retire the preliminary bcl wrapper
