__builtin_nop
Description:
Generates a nop instruction.
Prototype:
void _ _builtin_nop(void);
Argument:
None.
Return Value:
Returns a no operation (nop).
Assembler Operator / Machine Instruction:
nop
__builtin_psvoffset
Description:
Returns the psv page offset of the object whose address is given as a parameter. The argument
p must be the address of an object in an EE data, PSV or executable memory space; otherwise
an error message is produced and the compilation fails. See the space attribute in
Section 2.3.1 “Specifying Attributes of Variables” of the “MPLAB
®
C Compiler for PIC24
MCUs and dsPIC
®
DSCs User’s Guide” (DS51284).
Prototype:
unsigned int __builtin_psvoffset(const void *p);
Argument:
p object address
Return Value:
Returns the psv page number offset of the object whose address is given as a parameter.
Assembler Operator / Machine Instruction:
psvoffset
Error Messages:
The following error message is produced when this function is used incorrectly:
“Argument to _ _builtin_psvoffset() is not the address of an object in code, psv, or
eedata section”.
The argument must be an explicit object address.
For example, if obj is object in an executable or read-only section, the following syntax is valid:
unsigned page = _ _builtin_psvoffset(&obj);
