Implement a more cache-friendly translation of lookup switches. Previously,
for a switch such as the one in
:- pred p(foo::in, string::out, bar::out, float::out) is semidet.
p(d, "four", f1, 4.4).
p(e, "five", f2, 5.5).
p(f, "six", f4("hex"), 6.6).
p(g, "seven", f5(77.7), 7.7).
we generated three static cells, one for each argument, and then indexed
into each one in turn to get the values of HeadVar__2, HeadVar__3 and
HeadVar__4. The different static cells each represent a column here.
Each of the loads accessing the columns will access a different cache block,
so with this technique we expect to get as many cache misses as there are
output variables.
This diff changes the code we generate to use a vector of static cells
where each cell represents a row. The assignments to the output variables
will now access the different fields of a row, which will be next to each
other. We thus expect only one cache miss irrespective of the number of output
variables, at least up to the number of variables that actually fit into one
cache block.
compiler/global_data.m:
Provide a mechanism for creating not just single (scalar) static cells,
but arrays (vectors) of them.
compiler/lookup_switch.m:
Use the new mechanism to generate code along the lines described above.
Put the information passed between the two halves of the lookup switch
implementation (detection and code generation) into an opaque data
structure.
compiler/switch_gen.m:
Conform to the new interface of lookup_switch.m.
compiler/ll_pseudo_type_info.m:
compiler/stack_layout.m:
compiler/string_switch.m:
compiler/unify_gen.m:
compiler/var_locn.m:
Conform to the change to global_data.m.
compiler/llds.m:
Define the data structures for holding vectors of static cells. Rename
the function symbols we used to use to refer to static cells to make
clear that they apply to scalar cells only. Provide similar mechanisms
for representing static cell vectors and references to them.
Generalize heap_ref heap references to allow the index to be computed
at runtime, not compile time. For symmetry's sake, do likewise
for stack references.
compiler/llds_out.m:
Add the code required to write out static cell vectors.
Rename decl_ids to increase clarity and avoid ambiguity.
compiler/code_util.m:
compiler/exprn_aux.m:
Modify code that traverses rvals to now also traverse the new rvals
inside memory references.
compiler/name_mangle.m:
Provide the prefix for static cell vectors.
compiler/layout_out.m:
compiler/rtti_out.m:
compiler/opt_debug.m:
Conform to the change to data_addrs and decl_ids.
compiler/code_info.m:
Provide access to the new functionality in global_data.m, and conform
to the change to llds.m.
Provide a utility predicate needed by lookup_switch.m.
compiler/hlds_llds.m:
Fix the formatting of some comments.
tools/binary:
tools/binary_step:
Fix the bit rot that has set in since they were last used (the rest
of the system has changed quite a lot since then). I had to do so
to debug one part of this change.
tests/hard_coded/dense_lookup_switch2.{m,exp}:
tests/hard_coded/dense_lookup_switch3.{m,exp}:
New test cases to exercise the new algorithm.
tests/hard_coded/Mmakefile:
Enable the new test cases, as well as an old one (from 1997!)
that seems never to have been enabled.

% This module contains code to output the RTTI data structures defined in
|
|
% rtti.m as C code.
|
|
%
|
|
% This module is part of the LLDS back-end. The decl_set data type that it
|
|
% uses, which is defined in llds_out.m, represents a set of LLDS declarations,
|
|
% and thus depends on the LLDS. Also the code to output code_addrs depends on
|
|
% the LLDS.
|
|
%
|
|
% The MLDS back-end does not use this module; instead it converts the RTTI
|
|
% data structures to MLDS (and then to C or Java, etc.).
