DESCRIPTION

mcc is a machine code compiler. It reads binary ASCII text '0' and '1' mapping to machine code instructions. All other characters are ignored except the comment token ';'. Comments begin with ';' and continue until EOL. The -h option enables parsing hexadecimal rather than binary text.
Use the -o option to specify the output filename. The default is to put the executable in a.out.
Supports little-endian x86-64 and i386 execution environments using the System V application binary interface. 64-bit is the default mode, 32-bit mode is specified with the -3 option.
When writing to the .bss section, specify the size of memory reserved using the -m option. If the size is zero (default), no .bss section will be written for the executable.
In 64-bit mode the .bss and .text sections start at 0x402000 and 0x401000 respectively, and in 32-bit mode 0x804a000 and 0x8049000 respectively. Use the -b and -t options to specify custom addresses.
Program header segment alignment is set to 0x1000 (the page size on most systems).
.bss is aligned to a 16-byte constraint and .text to an 8-byte constraint.
Use the -s option to mark the .text section as writable, allowing self-modifying code.
