Define Documentation

#define REG_LR (   )     0

Fetches the value of the current LR (link register) This is a NOOP on non PPC750 platforms. Returns: 0, always

#define REG_MSR (   )     0

Fetches the value of the current MSR (machine status register) This is a NOOP on non PPC750 platforms. Returns: 0, always

#define REG_PC (   )     0

Fetches the value of the current PC. This is a NOOP on non PPC platforms. Returns: 0, always

#define REG_PVR (   )     0

Fetches the value the Processor Version Register, effectively a NOOP on non PPC platforms. Returns: 0, always Warning: This macro is provided only a portability aid. No code running on a non PPC platform should depend on the results of this macro.

#define REG_SP (   )     0

Fetches the value of the current Stack Pointer This is a NOOP on PPC platforms. Returns: The value of stack pointer where this macro is called The exact value of the SP is not specified and differs on an implementation by implementation basis. Since it is only meant to be indicate roughly where the SP is, this should cause no problems.

#define REG_SP (   )     0

Fetches the value of the current Stack Pointer This is a NOOP on PPC platforms. Returns: The value of stack pointer where this macro is called The exact value of the SP is not specified and differs on an implementation by implementation basis. Since it is only meant to be indicate roughly where the SP is, this should cause no problems.

#define REG_SPR (  _spr   )     0

Fetches the value the specified SPR. Returns: The value the specified SPR Parameters: _spr  The SPR register number. Warning: This macro is provided only a portability aid. No code running on a non PPC platform should depend on the results of this macro.
