altivec_vrsave
Description:
Controls whether or not Altivec registers should be saved between function calls.
Compatibility:
This pragma is compatible with the following platform targets:
Prototype:
#pragma altivec_vrsave on | off | reset | allon
Remarks:
When this option is on, the compiler generates extra instructions at the beginning and end of functions to set VRSave register to specify which Altivec registers should be saved. When allon is used, all Altivec registers will be saved.
To check whether this option is on, use __option (altivec_vrsave), described in "Checking Options."
