N19 Reference Compiler
Made to compile fast and produce acceptable output. Currently only 386 output supported (protected and partially real mode).
Composed of the following passes:
- Lexing
- Parsing & loop_second_pass
- Dumbification
- Codegen
UD-chains are generated during parsing. Codegen uses on primitive patterns within the AST, possible thanks to dumbification. This technique is applicable owing to Nectar's already low-level nature
Installation
make
sudo make install
Command-line usage
ntc arg1=val1 arg2=val2 ... argn=valn
Valid arguments
This will be ported into a man page later:
(TBA) x86_target: Target processor feature set (0 for 8086, 3 for 80386, m for generic x86_64)
(TBA) x86_mode: Target operating mode (16 for 16-bit real mode, 32 for 32-bit protected mode or long mode, 64 for 64-bit long mode)
in: Input Nectar source file
Unknown arguments are ignored.
Example
$ ntc < tests/bf.nct > out.asm
$ nasm -f elf -o out.o out.asm
$ ld -dynamic-linker /lib/ld-linux.so.2 -m elf_i386 -o bf out.o -lc
$ ./bf < tests/mandelbrot.b
