Nios II C2H Compiler User Guide
int tmp = 1, i;
for (i = 0 ;i<x;i++)
{
}
return tmp;
tmp *= (i+1);
Function Specifiers (Section 6.7.4)
The inline function specifier is ignored in the C2H design flow. The
build process uses the nios2-elf-gcc option –fno-inline.
Functions Declared Without a Return Type
The C2H compiler does not support functions without an explicitly
declared return type. If you are using the implicit int return type, declare
the return type explicitly. If your function has no return value, declare it
as void.
Miscellaneous Unsupported Features
The C2H Compiler does not support the features of ANSI C listed in this
section.
Goto (Section 6.8.6.1)
The goto keyword is not supported.
Identifiers (Section 6.4.2.2)
The predefined identifier __func__ is not supported.
Trigraph Sequences (Section 5.2.1.1)
The use of trigraph sequences to reduce the standard C character set to
the smaller ISO 646 character set is not supported.
The following function call uses unsupported trigraph “??<“ in place of
“{“:
