Note that basic asm is part of the standard C++ syntax. "An asm
declaration has the form
asm-definition:
asm ( string-literal ) ;
The asm declaration is conditionally-supported; its meaning is
implementation-defined. [ Note: Typically
it is used to pass information through the implementation to

There's a proposal working through the C++ committee to define the order
of evaluation of subexpressions that previously had unspecified ordering:

I agree with much of this, but was concerned about the proposal to
define order

Here is a test that shows that on at least PowerPC the basic asm is
