Clang generates a warning if the format string of a printf-like function is
not a literal ("-Wformat-nonliteral"). On the default configuration, it
causes a build failure (unless "--disable-werror" is specified).
To avoid warnings on the printf-like wrapper, it requires proper
__attribute__((format)) and we have ATTRIBUTE_PRINTF macro for this reason.
This commit adds ATTRIBUTE_PRINTF to the printf-like functions.
For the error function defined in sim_calls.c, the ATTRIBUTE_NORETURN
has been moved to the function declaration.

These functions provide the interface between the modeled targets

environment.

The underlying model is responsible for co-ordinating I/O

interactions such as:

close(1);
|

write(out, mess, sizeof(mess))

|

|
That is to say, the underlying model would, in implementing dup()
|
|
recorded the fact that any output directed at fid-OUT should be
|
|
displayed using sim_io_write_stdout(). While for the code stub:
|
|
|
|
main()
|
|
{
|
|
const char mess[] = "Hello World\r\n";
|
|
int out;
|
|
close(1);

out = open("output", 0x0001|0x0200, 0); // write+create
|
|
out = dup(1);
|
|
write(out, mess, sizeof(mess))

}

would result in output to fid-1 being directed towards the file
