Abstract
In an approach for locating, preserving, and receiving registers, a register located within a central processing unit is modified a preservation bit, wherein the preservation bit designates when the register is to be preserved. The preservation bit of the register is activated. A preservation bit requests a subroutine to access content held on the register. A register is pushed to a memory source. The bitmask is pushed to a memory source, wherein the bitmask contains information regarding the content pushed to the memory source. The bitmask is popped, at the request of the subroutine, to determine that that content is to be popped. The content is popped from the memory source to the register. The content is returned from the subroutine.
