From 5fd96fd51994f8a78491a266f80b30a34d1a6c7b Mon Sep 17 00:00:00 2001 From: Michael Beck Date: Tue, 21 Dec 2010 02:08:45 +0000 Subject: [PATCH] Obstack: Deleted the special windows version, make Win64 warning free. Use PTR_INT_TYPE instead of long which is 32bit on Win64.

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' an obstack - back to a previous state. (You may remove objects much - as you would with a stack.) -*/ - - -/* Don't do the contents of this file more than once. */ - -#ifndef _OBSTACK_H -#define _OBSTACK_H 1 - -/* use function from */ -#define HAVE_STRING_H 1 - -#ifdef __cplusplus -extern "C" { -#endif - -/* We use subtraction of (char *) 0 instead of casting to int - because on word-addressable machines a simple cast to int - may ignore the byte-within-word field of the pointer. */ - -#ifndef __PTR_TO_INT -# define __PTR_TO_INT(P) ((P) - (char *) 0) -#endif - -#ifndef __INT_TO_PTR -# define __INT_TO_PTR(P) ((void *)((P) + (char *) 0)) -#endif - -/* We need the type of the resulting object.
