+/* $Id$
+ *
+ * This file is a modified version of 'a.out.h'. It is to be used in all
+ * GNU tools modified to support the i80960 (or tools that operate on
+ * object files created by such tools).
+ *
+ * All i80960 development is done in a CROSS-DEVELOPMENT environment. I.e.,
+ * object code is generated on, and executed under the direction of a symbolic
+ * debugger running on, a host system. We do not want to be subject to the
+ * vagaries of which host it is or whether it supports COFF or a.out format,
+ * or anything else. We DO want to:
+ *
+ * o always generate the same format object files, regardless of host.
+ *
+ * o have an 'a.out' header that we can modify for our own purposes
+ * (the 80960 is typically an embedded processor and may require
+ * enhanced linker support that the normal a.out.h header can't
+ * accommodate).
+ *
+ * As for byte-ordering, the following rules apply:
+ *
+ * o Text and data that is actually downloaded to the target is always
+ * in i80960 (little-endian) order.
+ *
+ * o All other numbers (in the header, symbols, relocation directives)
+ * are in host byte-order: object files CANNOT be lifted from a
+ * little-end host and used on a big-endian (or vice versa) without
+ * modification.
+ * ==> THIS IS NO LONGER TRUE USING BFD. WE CAN GENERATE ANY BYTE ORDER
+ * FOR THE HEADER, AND READ ANY BYTE ORDER. PREFERENCE WOULD BE TO
+ * USE LITTLE-ENDIAN BYTE ORDER THROUGHOUT, REGARDLESS OF HOST. <==
+ *
+ * o The downloader ('comm960') takes care to generate a pseudo-header
+ * with correct (i80960) byte-ordering before shipping text and data
+ * off to the NINDY monitor in the target systems. Symbols and
+ * relocation info are never sent to the target.

+/* Summary:
+
+All the apparent functions defined here are macros. The idea
+is that you would use these pre-tested macros to solve a
+very specific set of problems, and they would run fast.
+Caution: no side-effects in arguments please!! They may be
+evaluated MANY times!!
+
+These macros operate a stack of objects. Each object starts life
+small, and may grow to maturity. (Consider building a word syllable
+by syllable.) An object can move while it is growing. Once it has
+been "finished" it never changes address again. So the "top of the
+stack" is typically an immature growing object, while the rest of the
+stack is of mature, fixed size and fixed address objects.
+
+These routines grab large chunks of memory, using a function you
+supply, called `obstack_chunk_alloc'. On occasion, they free chunks,
+by calling `obstack_chunk_free'. You must define them and declare
+them before using any obstack macros.
+
+Each independent stack is represented by a `struct obstack'.
+Each of the obstack macros expects a pointer to such a structure
+as the first argument.
+
+One motivation for this package is the problem of growing char strings
+in symbol tables. Unless you are "fascist pig with a read-only mind"
+[Gosper's immortal quote from HAKMEM item 154, out of context] you
+would not like to put any arbitrary upper limit on the length of your
+symbols.
+
+In practice this often means you will build many short symbols and a
+few long symbols. At the time you are reading a symbol you don't know
+how long it is. One traditional method is to read a symbol into a
+buffer, realloc()ating the buffer every time you try to read a symbol
+that is longer than the buffer. This is beaut, but you still will
+want to copy the symbol from the buffer to a more permanent
+symbol-table entry say about half the time.
+
+With obstacks, you can work differently. Use one obstack for all symbol
+names. As you read a symbol, grow the name in the obstack gradually.
+When the name is complete, finalize it. Then, if the symbol exists already,
+free the newly read name.
+
+The way we do this is to take a large chunk, allocating memory from
+low addresses. When you want to build a symbol in the chunk you just
+add chars above the current "high water mark" in the chunk. When you
+have finished adding chars, because you got to the end of the symbol,
+you know how long the chars are, and you can create a new object.
+Mostly the chars will not burst over the highest address of the chunk,
+because you would typically expect a chunk to be (say) 100 times as
+long as an average object.
+
+In case that isn't clear, when we have enough chars to make up
+the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed)
+so we just point to it where it lies. No moving of chars is
+needed and this is the second win: potentially long strings need
+never be explicitly shuffled. Once an object is formed, it does not
+change its address during its lifetime.
+
+When the chars burst over a chunk boundary, we allocate a larger
+chunk, and then copy the partly formed object from the end of the old
+chunk to the beginning of the new larger chunk. We then carry on
+accreting characters to the end of the object as we normally would.
+
+A special macro is provided to add a single char at a time to a
+growing object. This allows the use of register variables, which
+break the ordinary 'growth' macro.
+
+Summary:
+ We allocate large chunks.
+ We carve out one object at a time from the current chunk.
+ Once carved, an object never moves.
+ We are free to append data of any size to the currently
+ growing object.
+ Exactly one object is growing in an obstack at any one time.
+ You can run one obstack per control block.
+ You may have as many control blocks as you dare.
+ Because of the way we do it, you can `unwind' a obstack
+ back to a previous state. (You may remove objects much
+ as you would with a stack.)
