.SH NAME
|
|
|
|
M2-Planet \- The PLAtform NEutral Transpiler (Or just terrible C compiler)
|
|
|
|
.SH SYNOPSIS
|
|
.na
|
|
|
|
M2-Planet --architecture ARCHITECTURE --file FILE [--output FILE] [--debug]
|
|
|
|
.SH DESCRIPTION
|
|
|
|
M2 is the most minimal C compiler that can be bootstrapped from Hex
|
|
.br
|
|
At it's core is the minimal subset of the C language required
|
|
to make a more powerful C compiler. (with a few extras for convience)
|
|
|
|
.br
|
|
Those core primitives being: if (with continue), while (with
|
|
break), asm, structs (with -> support) gotos (with labels) and return.
|
|
|
|
With do and for loops, arrays and function pointers as nice extras
|
|
.br
|
|
The supported ARCHITECTURES are as follows: knight-native,
|
|
knight-posix, x86, amd64, armv7l, aarch64.
|
|
(with planned ports to z80 and 6502)
|
|
If you fail to specify an architecture, the default of knight-native
|
|
will be used.
|
|
|
|
.br
|
|
|
|
As M2-Planet's libc is literally only a half-dozen lines of assembly
|
|
you will likely need to import libc primitives when building or
|
|
having previously built them seperately.
|
|
|
|
You can find examples for such primitives in:
|
|
test/common_x86/functions/
|
|
test/common_amd64/functions/
|
|
test/common_armv7l/functions/
|
|
test/common_aarch64/functions/
|
|
test/common_knight/functions/
|
|
|
|
with the default libc implementations and elf-headers in the
|
|
parent directories correspondingly.
|
|
|
|
.br
|
|
|
|
.SH EXAMPLES
|
|
|
|
Typically, M2-Planet will be called in scripts used in bootstrapping
|
|
|
|
.br
|
|
# M2-Planet --architecture x86 -f return.c -o return.M1
|
|
.br
|
|
|
|
Then to convert the assembled output into a working binary,
|
|
M1 and hex2 are used to convert the assembly output of M2-Planet;
|
|
with blood-elf generating dwarf stubs if additional debug info is
|
|
desired.
|
|
.br
|
|
|
|
# M1 -f test/common_x86/x86_defs.M1 -f test/common_x86/libc-core.M1 \
|
|
-f return.M1 --LittleEndian --architecture x86 -o return.hex2
|
|
|
|
|
|
# hex2 -f test/common_x86/ELF-i386.hex2 -f return.hex2 --LittleEndian \
|
|
--architecture x86 --BaseAddress 0x8048000 -o example --exec_enable
|
|
.br
|
|
|
|
.SH COMPATIBILITY
|
|
|
|
M2-Planet is compatible with all Turing complete machines;
|
|
even the ones that try to be Turing complete -1
