Macros for SDB and DWARF Output

Here are macros for SDB and DWARF output.

SDB_DEBUGGING_INFO

Define this macro if GNU CC should produce COFF-style debugging output for SDB in response to the `-g' option.

DWARF_DEBUGGING_INFO

Define this macro if GNU CC should produce dwarf format debugging output in response to the `-g' option.

DWARF2_DEBUGGING_INFO

Define this macro if GNU CC should produce dwarf version 2 format debugging output in response to the `-g' option. To support optional call frame debugging information, you must also define INCOMING_RETURN_ADDR_RTX and either set RTX_FRAME_RELATED_P on the prologue insns if you use RTL for the prologue, or call dwarf2out_def_cfa and dwarf2out_reg_save as appropriate from FUNCTION_PROLOGUE if you don't.

PUT_SDB_...

Define these macros to override the assembler syntax for the special SDB assembler directives. See `sdbout.c' for a list of these macros and their arguments. If the standard syntax is used, you need not define them yourself.

SDB_DELIM

Some assemblers do not support a semicolon as a delimiter, even between SDB assembler directives. In that case, define this macro to be the delimiter to use (usually `\n'). It is not necessary to define a new set of PUT_SDB_op macros if this is the only change required.

SDB_GENERATE_FAKE

Define this macro to override the usual method of constructing a dummy name for anonymous structure and union types. See `sdbout.c' for more information.

SDB_ALLOW_UNKNOWN_REFERENCES

Define this macro to allow references to unknown structure, union, or enumeration tags to be emitted. Standard COFF does not allow handling of unknown references, MIPS ECOFF has support for it.

SDB_ALLOW_FORWARD_REFERENCES

Define this macro to allow references to structure, union, or enumeration tags that have not yet been seen to be handled. Some assemblers choke if forward tags are used, while some require it.
