Arm Compiler armasm User Guide : FRAME RESTORE

FRAME RESTORE

The FRAME RESTORE directive informs the assembler that the contents of specified registers have been restored to the values they had on entry to the function.

Syntax

FRAME RESTORE {reglist}

where:

reglist

is a list of registers whose contents have been restored. There must be at least one register in the list.

Usage

You can only use FRAME RESTORE within functions with FUNCTION and ENDFUNC or PROC and ENDP directives. Use it immediately after the callee reloads registers from the stack. You do not have to do this after the last instruction in a function.

reglist can contain integer registers or floating-point registers, but not both.

Note

If your code uses a single instruction to load registers and alter the stack pointer, you can use FRAME POP instead of using both FRAME RESTORE and FRAME ADDRESS.
