Guarantees that the given SPARCAddress given before is loadable by subsequent load/store instruction. If the displacement exceeds the simm13 value range, the value is put into a scratch register.

Parameters:

addr - Address to modify

masm - assembler to output the potential code to store the value in the scratch register

scratch - The register as scratch to use

Returns:

a loadable SPARCAddress

This method creates a load from the constant section. It automatically respects the different patterns used for small constant sections (<8k) and large constant sections (>=8k). The generated patterns by this method must be understood by CodeInstaller::pd_patch_DataSectionReference (jvmciCodeInstaller_sparc.cpp).
