void dw2_asm_output_addr ( int  size,
const char *  label,
const char *  comment,
  ... 
)

Output an absolute reference to a label.

void dw2_asm_output_addr_rtx ( int  size,
rtx  addr,
const char *  comment,
  ... 
)

Similar, but use an RTX expression instead of a text label.

void dw2_asm_output_data ( int  size,
unsigned HOST_WIDE_INT  value,
const char *  comment,
  ... 
)

Output an immediate constant in a given SIZE in bytes.

Referenced by add_pubtype(), calc_die_sizes(), output_aranges(), output_die(), output_ranges(), schedule_generic_params_dies_gen(), and size_of_aranges().

void dw2_asm_output_data_raw ( int  ,
unsigned  HOST_WIDE_INT 
)
void dw2_asm_output_data_sleb128 ( HOST_WIDE_INT  value,
const char *  comment,
  ... 
)

Output a signed LEB128 quantity.

void dw2_asm_output_data_uleb128 ( unsigned HOST_WIDE_INT  value,

Output an unsigned LEB128 quantity.

void dw2_asm_output_data_uleb128_raw ( unsigned  HOST_WIDE_INT)
void dw2_asm_output_delta ( int  size,
const char *  lab1,
const char *  lab2,
const char *  comment,
  ... 
)

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.

)
void dw2_asm_output_encoded_addr_rtx ( int  encoding,
rtx  addr,
bool  is_public,
const char *  comment,
  ... 
)

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).

 NULL is <em>always</em> represented as a plain zero, as is 1 for Ada's
 "all others".   
     Allow the target first crack at emitting this.  Some of the
     special relocations require special directives instead of
     just ".4byte" or whatever.   
     Indirection is used to get dynamic relocations out of a
     read-only section.   
         It is very tempting to use force_const_mem so that we share data
         with the normal constant pool.  However, we've already emitted
         the constant pool for this function.  Moreover, we'd like to
         share these constants across the entire unit of translation and
         even, if possible, across the entire application (or DSO).   
         Other encodings should have been handled by
         ASM_MAYBE_OUTPUT_ENCODED_ADDR_RTX.   

References dw2_force_const_mem().

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

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.

If an explicit length was given, we can't assume there is a null termination in the string buffer.

References ASM_COMMENT_START.

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

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.

Referenced by output_die(), and unmark_all_dies().

void dw2_asm_output_vms_delta ( int  size,
const char *  lab1,
const char *  lab2,
const char *  comment,
  ... 
)

Output the difference between two symbols in instruction units in a given size.

VMS Delta is only special on ia64-vms, but this function also gets called on alpha-vms so it has to do something sane.
