Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.

/* Output dbx-format symbol table data.
This consists of many symbol table entries, each of them
a .stabs assembler pseudo-op with four operands:
a "name" which is really a description of one symbol and its type,
a "code", which is a symbol defined in stab.h whose name starts with N_,
an unused operand always 0,
and a "value" which is an address or an offset.
The name is enclosed in doublequote characters.
Each function, variable, typedef, and structure tag
has a symbol table entry to define it.
The beginning and end of each level of name scoping within
a function are also marked by special symbol table entries.
The "name" consists of the symbol name, a colon, a kind-of-symbol letter,
and a data type number. The data type number may be followed by
"=" and a type definition; normally this will happen the first time
the type number is mentioned. The type definition may refer to
other types by number, and those type numbers may be followed
by "=" and nested definitions.
This can make the "name" quite long.
When a name is more than 80 characters, we split the .stabs pseudo-op
into two .stabs pseudo-ops, both sharing the same "code" and "value".
The first one is marked as continued with a double-backslash at the
end of its "name".
The kind-of-symbol letter distinguished function names from global
variables from file-scope variables from parameters from auto
variables in memory from typedef names from register variables.
See `dbxout_symbol'.
The "code" is mostly redundant with the kind-of-symbol letter
that goes in the "name", but not entirely: for symbols located
in static storage, the "code" says which segment the address is in,
which controls how it is relocated.
The "value" for a symbol in static storage
is the core address of the symbol (actually, the assembler
label for the symbol). For a symbol located in a stack slot
it is the stack offset; for one in a register, the register number.
For a typedef symbol, it is zero.
If DEBUG_SYMS_TEXT is defined, all debugging symbols must be
output while in the text section.
For more on data type definitions, see `dbxout_type'. */

Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.

Fix conflicts. This brings rev 1.2 (fix stabs ordering for a.out) into EGCS 1.1.2.
