3.1 C Preprocessor Predefines
All C/C++ language compilers must have predefined macros as in Table 3-1, in addition to the predefined
macros required by the C and C++ language standards.
3.2 C In-Line Assembly Syntax
A C in-line assembly syntax must be provided. At a minimum, a single line assembly has to be supported:
3.3 C Name Mapping
Externally visible names in the C language are prefixed by “_” when generating assembly language
symbol names. For example, the following:
generates assembly code similar to the following fragment:
SC100 Application Binary Interface
__SC100__
Macro
asm(“wait”);
{
}
_testfunc:
void testfunc()
