extern

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.

		bool	is_public,
		const char *	comment,

extern

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).

void dw2_asm_output_nstring	(	const char *	str,
		size_t	orig_len,
		const char *	comment,
			... )

extern

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.

◆ dw2_asm_output_offset() [2/2]

void dw2_asm_output_offset	(	int	size,
		const char *	label,
		section *	base,
		const char *	comment,
			... )

extern

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.

◆ dw2_asm_output_symname_uleb128()

void dw2_asm_output_symname_uleb128	(	const char *	lab1,
		const char *	comment,
			... )

extern

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.

References ap, ASM_COMMENT_START, asm_out_file, assemble_name(), fputc(), gcc_unreachable, and vfprintf().

extern

◆ dw2_assemble_integer()

void dw2_assemble_integer	(	int	size,
		rtx	x )

extern

◆ dw2_force_const_mem()

rtx dw2_force_const_mem	(	rtx	x,
		bool	is_public )

extern

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).
