Hai everyone,

I am asking this just out of curiosity.

I am using Microchip C30 compiler to develop EEPROM driver code for PIC24F.
During this I used C30 builtin functions such as
__builtin_tblwtl(), __builtin_tbloffset etc.
How can I find the location of builtin functions? From Wiki I found this:
Some compilers (for example, GCC[7]) provide built-in versions of many of the functions in the C standard library; that is, the implementations of the functions are written into the compiled object file, and the program calls the built-in versions instead of the functions in the C library shared object file
Click to expand...

Does this mean that these functions are written inside the object files of compiler?So does that mean we cannot see it as a code?
I have searched the entire C30 directory and didn't find these functions.

Thank you
 

Built-in usually means, the code is generated by the compiler. You'll see in in a disassembler view, probably without any comments.
 

Hai,
Ok, so the code is compiler generated. I was searching for the source code of builtin functions in the compiler installed directory. Now,I saw the assembly code in Disassembly listing.

Thank You
