I hope no one else feels this way. It is not true. For example, in the assembler services guide, linkage conventions section: Unless otherwise defined by the individual interface, the calling program should expect, upon return, that The low halves (Bits 32-63) of GPRs 2 through 13 are unchanged The high halves (Bits 0-31) of GPRs 2 through 14 are unchanged ARs 2 through 13 are unchanged FPRs 8 through 15 are unchanged; The Floating Point Control (FPC) Register is unchanged with the exception of two fields: the IEEE exception flags and the data exception code (DXC).
