You use the way that is defined in the C++ standard:

asm(" ........ ");

So you would do:
---
asm(
    "movb $0x20, %ah \n"
    "movb %ah, %bl \n"
    "incb %bl \n"
    "addb %bl, %ah \n"
);
---

Remember, GCC uses AT&T syntax by default. If you want to work with 
Intel syntax use the "-masm" option:

|-masm=|dialect||
    Output asm instructions using selected dialect. Supported choices 
are |intel| or |att| (the default one).
