SYNOPSIS

ragg2-cc [-a arch] [-b bits] [-k kernel] [-o file] [-dscxvh]

DESCRIPTION

ragg2-cc is a frontend of CC. It is used to creates tiny binaries (1KB) or shellcodes in binary or hexpairs from a C source.

The compiler used is the one configured by the CC environment. This has been tested with gcc, llvm-gcc and clang.

Uses sflib (shellforge4) includes to get the syscall definitions.

Only linux/darwin x86-32/64 is supported at the moment. Planned support for more architectures.

OPTIONS

-a arch
  set architecture x86, arm
-b bits
  32 or 64
-k kernel
  windows, linux or osx
-o file
  output file to write result of compilation
-h show help message
-v show version
-d show assembler code
-s generate assembly file
-c generate compiled shellcode
-x show hexpair bytes

EXAMPLE

$ cat hi.c
int main() {
write (1, "Hello World\n", 12);
exit (0);
}

$ ragg2-cc hi.c
hi.c.bin

# Linked into a tiny binary. This is 294 bytes
$ wc -c < hi.c.bin
294

$ ./hi.c.bin
Hello World

# The compiled shellcode has zeroes
$ ragg2-cc -x hi.c
