/* Implement TARGET_ASM_FUNCTION_RODATA_SECTION.
The complication here is that, with the combination TARGET_ABICALLS
&& !TARGET_GPWORD, jump tables will use absolute addresses, and should
therefore not be included in the read-only part of a DSO. Handle such
cases by selecting a normal data section instead of a read-only one.
The logic apes that in default_function_rodata_section. */
