??? It is known that if it were an array of entries, structure elements

`next_same_hash' and `bitmap_index' wouldn't be necessary. However, it is

not clear whether in the final analysis a sufficient amount of memory would

be saved as the size of the available expression bitmaps would be larger

[one could build a mapping table without holes afterwards though].

Assignment entries are placed in the hash table if

- they are of the form (set (pseudo-reg) src),
|
|
|
|
|
- src is something we want to perform const/copy propagation on,
|
|
|
|
|
- none of the operands or target are subsequently modified in the block
|
|
|
|

|

Currently src must be a pseudo-reg or a const_int.

Remove REAL_VALUE_FROM_CONST_DOUBLE
To maintain symmetry after the previous removal of
CONST_DOUBLE_FROM_REAL_VALUE, this patch also gets rid of
REAL_VALUE_FROM_CONST_DOUBLE. All the macro did was copy the
contents of CONST_DOUBLE_REAL_VALUE into a temporary real_value
structure. In many cases there was no need for this temporary
and we could simply use the CONST_DOUBLE_REAL_VALUE directly.
For that reason this patch is less automatic than the others.
Bootstrapped & regression-tested on x86_64-linux-gnu. Also tested by
building one target per CPU directory and checking that there were
no new warnings and no changes in testsuite output at -O2.
