こんなボクでもやっとC言語でHello, World!が書けるようになりました！ ref: http://qiita.com/make_now_just/items/e7a92a64a613a50ea698

hello.c

const char main[]="H1\xc0H\xff\xc0H\x89\xc7H1\xd2H\2155\xb\0\0\0\xb2\xe\xf\5\xb0\x3cH1\xff\xf\5Hello, World!\n";

hello_orig.c

const char main[] =
/* main: */
"\x48\x31\xc0"                 /* xor %rax, %rax */
"\x48\xff\xc0"                 /* inc %rax */
"\x48\x89\xc7"                 /* mov %rax, %rdi */
"\x48\x31\xd2"                 /* xor %rdx, %rdx */
"\x48\x8d\x35\x0b\x00\x00\x00" /* lea msg(%rip), %rsi */
"\xb2\x0e"                     /* mov $14, %dl */
"\x0f\x05"                     /* syscall */
"\xb0\x3c"                     /* mov $60, %ral */
"\x48\x31\xff"                 /* xor %rdi, %rdi */
"\x0f\x05"                     /* syscall */
/* msg: */
"Hello, World!\n";
