How to use asm in C++?
Hongkun Liang
Hi, I want to write some lines in C++ by asm
command. But I don't know how to pass a variable
to the asm command.
Thanks!

Could you please provide a reference to the standard for this
assertion? I doubt that you can do better than appendix G.5.10, but
this will hardly do, since the use of asm as a keyword "rendeers an
implementation nonconforming." 'asm' is NOT a reserved keyword in C.

: asm is a reserved keyword in C, but its implementation is compiler and
: platform specific. If possible try doing a search for asm in the source
: files for the system for sample code. In most of the implementations I've
: seen, you shouldn't have to write the interface in assembler (e.g.):
asm isn't reserved in C89 - it might be in C9X, I don't know.

It isn't. Its status in K.5.10 in n843 is the same G.5.10 of 9899:1990.
If your implementation makes it a keyword, you break legal code,
rendering your implementation non-conforming.

reference, but it's good enough for me). Appendix A2.4 "Keywords" where it
says that "Some implementations also reserve the words fortran and asm.", so
I guess I'm not 100% correct. I won't be losing any sleep over it though.
