Output the difference between two symbols in a given size.
??? There appear to be assemblers that do not like such subtraction, but do support ASM_SET_OP. It's unfortunately impossible to do here, since the ASM_SET_OP for the difference symbol must appear after both symbols are defined.

Like dw2_asm_output_addr_rtx, but encode the pointer as directed. If PUBLIC is set and the encoding is DW_EH_PE_indirect, the indirect reference is shared across the entire application (or DSO).

Output the first ORIG_LEN characters of STR as a string. If ORIG_LEN is equal to -1, ignore this parameter and output the entire STR instead. If COMMENT is not NULL and comments in the debug information have been requested by the user, append the given COMMENT to the generated output.

Output a section-relative reference to a LABEL, which was placed in BASE. In general this can only be done for debugging symbols. E.g. on most targets with the GNU linker, this is accomplished with a direct reference and the knowledge that the debugging section will be placed at VMA 0. Some targets have special relocations for this that we must use.

Output symbol LAB1 as an unsigned LEB128 quantity. LAB1 should be an assembler-computed constant, e.g. a view number, because we can't have relocations in LEB128 quantities.

Put X, a SYMBOL_REF, in memory. Return a SYMBOL_REF to the allocated memory. Differs from force_const_mem in that a single pool is used for the entire unit of translation, and the memory is not guaranteed to be "near" the function in any interesting sense. IS_PUBLIC controls whether the symbol can be shared across the entire application (or DSO).
