3.5.3 Integer Routines
The integer routines listed in Table 3-4 should comply with the ABI calling conventions. The routines have
no side effects.
3.6 Function Argument and Return Type Checking
in C
Level 1 conforming implementations support the following mechanism for checking that arguments and
return types of function calls match the called functions’ signatures.
3.6.1 Signature Symbols
For every direct call to a non-static function in a source file (i.e., a call using the function name as opposed
to a call through a function pointer), the compiler system produces in the ELF object file a symbol of the
following convention:
For every non-static function definition, the compiler system produces a symbol of the following
convention:
Table 3-5 explains the construction of the italized fields in the symbol names:
