/* This isn't quite a "constant" pool. Some of the values may get
|
|
adjusted at run time, e.g., for symbolic relocations when shared
|
|
libraries are in use. It's more of a "literal" pool.
|
|
|
|
On the Alpha, this should be used for .lita and .lit8. (Is there
|
|
ever a .lit4?) On the MIPS, it could be used for .lit4 as well.
|
|
|
|
The expressions passed here should contain either constants or symbols,
|
|
not a combination of both. Typically, the constant pool is accessed
|
|
with some sort of GP register, so the size of the pool must be kept down
|
|
if possible. The exception is section offsets -- if you're storing a
|
|
pointer to the start of .data, for example, and your machine provides
|
|
for 16-bit signed addends, you might want to store .data+32K, so that
|
|
you can access all of the first 64K of .data with the one pointer.
|
|
|
|
This isn't a requirement, just a guideline that can help keep .o file
|
|
size down. */
