The two target implementations are very close clones of each other. The only known differences are the following: * The asm component of the linux target has `.type` and `.size` declarations for the functions defined therein, while the darwin target doesn't support those. * Linux uses `__NR_xxx` mnemonics for syscall numbers, while darwin uses `SYS_xxx` format. * Darwin does not have `exit_group` syscall but `exit` only. * The linux target has a commented out `jrt_set_mem_limits` fuction declaration at the end of the C source. (Based on its name, this function does not really belong here.) Simple preprocessor macros can unify the first three differences. While for the sake of legacy, we can keep the fourth commented-out code in the code base; it might turn out to be useful elsewhere in the future. Since it remains commented out it wont cause any problems on any OSs. So, this patch gets rid of a lot of duplication. JerryScript-DCO-1.0-Signed-off-by: Akos Kiss akiss@inf.u-szeged.hu
