This is not less portable, it is very dangerous. Any change to your code might make the compiler use different registers for the temporary storage. This is the fundamental flaw in most attempts to mix inline assembler in 'C' source. That's why I always say: Don't mess with inline assembler; if it needs to be done in assembler, do it in a proper assembler module. |
