Hello everybody,
I have a strange problem with writing multi section C++ code using the
prc-tools 2.0. I have written the following class:
#include "HostFile.h" // This is an interface to the HostControl API
#define STRING_SECTION __attribute__ ((section ("String")))
...
class String {
private:
MemHandle valueHandle;
...
public:
...
String(char *) STRING_SECTION;
char *getValue() STRING_SECTION; // Locks valueHandle and returns
chunk
void ungetValue() STRING_SECTION; // Unlocks chunk
friend HostFile& operator <<(HostFile&, const String&) STRING_SECTION;
};
The friend function looks like this:
HostFile& operator <<(HostFile& h, const String& string) {
char *s = string.getValue();
HostFile& hfile = h << s; // Put s on the host stream
string.ungetValue();
return hfile;
}
Using the << operator in my code, e.g. with
HostFile hout = Hostfile("foo.log");
String s = String("foo");
hout << s << '\n';
I get a fatal error in Pose: "... just executed an illegal or unknown
machine language instruction. The opcode ... was 0xFFF8"
If I put the friend function into the default section, everything works
fine.
I have compiled the code with -fno-default-inline -fno-exceptions
-fno-rtti and linked it to libnoexcept.
Are there any restrictions to using friend functions in custom code
sections?
Cheers,
--Bernd Abel--
