intrinsic_function

[Jamber_H]

Hi, what's intrinsic_function meaning in flow code?

extern void __mtdcr( const unsigned int,  int) __attribute__((intrinsic_function(2090, 0, "mtdcr") ));

extern void __mtspr( const unsigned int,  int) __attribute__((intrinsic_function(2090, 4, "mtspr") ));

extern int __mfspr( const unsigned int) __attribute__((intrinsic_function(2016, 4, "mfspr") ));

Best regards,

Jamber

OK, but it is not a syntax use with S32 Design Studio or some of its component? Or is it?

The compiler is WindRiver, and IDE is S32DS.

I would apparently forward you to WindRiver support

https://www.windriver.com/support/index.html

because this question is specifically related to directives' syntax of Diab compiler.
