/* string blocks
|

|
I had a couple of choices when deciding upon this data structure.
|
|
gas uses null terminated strings for all its internal work. This
|
|
often means that parts of the program that want to examine
|
|
substrings have to manipulate the data in the string to do the
|
|
right thing (a common operation is to single out a bit of text by
|
|
saving away the character after it, nulling it out, operating on
|
|
the substring and then replacing the character which was under the
|
|
null). This is a pain and I remember a load of problems that I had with
|
|
code in gas which almost got this right. Also, it's harder to grow and
|
|
allocate null terminated strings efficiently.
|
|
|
|
Obstacks provide all the functionality needed, but are too
|
|
complicated, hence the sb.
|
|
|
|
An sb is allocated by the caller, and is initialized to point to an
|
|
sb_element. sb_elements are kept on a free lists, and used when
|
|
needed, replaced onto the free list when unused.
