// Helper function used by compiler to restore ppc floating point registers at
|
|
// the end of the function epilog. This function returns to the address
|
|
// in the LR slot. So a function epilog must branch (b) not branch and link
|
|
// (bl) to this function.
|
|
// If the compiler wants to restore f27..f31, it does a "b restFP+52"
|
|
//
|
|
// This function should never be exported by a shared library. Each linkage
|
|
// unit carries its own copy of this function.
