... as a preliminary for extending the emulation to sized ints and uints.
compiler/int_emu.m:
Move all the emulation operations from uint_emu.m to int_emu.m,
moving each uint operation next to its int equivalent. To make this
possible without naming conflicts, add a distinguishing prefix
to the name of each emulation predicate. (The emulations of each op
for signed and unsigned ints are related though somewhat different,
and both the similarities and differences are easily visible and checkable
when their code is next to each other.)
On the other hand, the emulation code for an operation for e.g.
int/int8/int16/int32/int64 can be *identical* when the number of bits
is a parameter of that code, and the next diff will exploit this fact.
Unify the target_bits_per_int predicate from int_emu.m and the
target_bits_per_uint predicate from uint_emu.m, which had exactly
the same logic, and call it target_word_bits.
compiler/uint_emu.m:
Delete this module.
compiler/libs.m:
Delete both int_emu.m and uint_emu as a submodule of this package.
compiler/parse_tree.m:
Move int_emu.m to become a submodule of this package, to allow the next
change to it to use the some_int_const type in prog_data.m.
compiler/notes/compiler_design.html:
Generalize the description of int_emu.m. Note that the description
of uint_emu.m cannot be deleted, because it didn't exist :-(
compiler/const_prop.m:
compiler/simplify_goal_call.m:
Conform to the changes above.
