whitequark ebbbe2156e flatten: rename techmap-related stuff. NFC. 2020-06-04 00:02:12 +00:00
whitequark 76c4ee4ea5 techmap, flatten: remove dead options. 
After splitting the passes, some options can never be activated,
and most conditions involving them become dead. Remove them, and also
all of the newly dead code.

whitequark 6ac54a74fe flatten: split from techmap. 
Although the two passes started out very similar, they diverged over
time and now have little in common. Moreover, `techmap` is extremely
complex while `flatten` does not have to be, and this complexity
interferes with improving `flatten`.

Add flooring division operator 
The $div and $mod cells use truncating division semantics (rounding
towards 0), as defined by e.g. Verilog. Another rounding mode, flooring
(rounding towards negative infinity), can be used in e.g. VHDL. The
new $divfloor cell provides this flooring division.

This commit also fixes the handling of $div in opt_expr, which was
previously optimized as if it was $divfloor.

in several languages, but this name is ambiguous).

Rupert Swarbrick d681c9df85 Pass some more args by reference in select.cc 
Before this patch, the code passed around std::string objects by
value. It's probably not a hot-spot, but it can't hurt to avoid the
copying.

Removing the copy and clean-up code means the resulting code is ~6.1kb
smaller when compiled with GCC 9.3 and standard settings.
 2020-05-27 09:42:23 +01:00
Rupert Swarbrick 061d1f0c07 Minor optimisations in select.cc's match_ids function 
- Pass a string argument by reference

  - Avoid multiple calls to IdString::str and IdString::c_str

  - Avoid combining checks for size > 0 and first char (C strings are
    null terminated, so foo[0] != '\0' implies that foo has positive
    length)
 2020-05-27 09:36:33 +01:00
Rupert Swarbrick 0d9beb5b2e Silence warning in select.cc 
With GCC 9.3, at least, compiling select.cc spits out a warning about
an implausible bound being passed to strncmp. This comes from inlining
IdString::compare(): it turns out that passing std::string::npos as a
bound to strncmp triggers it.

This patch replaces the compare call with a memcmp with the same
effect. The repeated calls to IdString::c_str are slightly
inefficient, but I'll address that in a follow-up commit.

misc: Add `printattrs` command. 2020-05-27 08:00:00 +00:00
Rupert Swarbrick 7746bba69a Simplify a modport check in hierarchy.cc 
This code originally comes from commit 458a940. When an interface is
used via a modport, code in genrtlil.cc sets '\\interface_type' and
'\\interface_modport' properties on the wire.

In hierarchy.cc, we pick up the modport name and add it to a dict
called modports_used_in_submodule (that maps connection source to
modport name).

Before this patch, the modport name is retrieved as a strpool and then
iterated over in an arbitrary order, discarding all entries but the
last. In practice, the pool will always have 0 or 1 entries because
the string used to construct it is a valid identifier, so doesn't
contain any pipe symbols.

This patch changes the code to retrieve the modport name as just a
string. This will have the same effect in practice, but may be a bit
less confusing!

The code also gets moved down closer to where the result is used,
which might be a bit more efficient since we won't always get as far
as the check.

The patch also removes some commented-out code, which I think was
intended to add some typechecking at some point, but was never
implemented. Since this dates back to October 2018, I think it makes
more sense to just take it out.

qbfsat: Add `-solver` option and allow choice of Z3 or Yices, making Yices the default. 
Ensures that "BV" is the logic whenever solving an exists-forall problem with Yices, moves the "(set-logic ...)" directive above any non-info line, sets the `ef-max-iters` parameter to a very high number when using Yices in exists-forall mode so as not to prematurely abandon difficult problems, and does not provide the incompatible "--incremental" Yices argument when in exists-forall mode.

whitequark b43c282e4e Add WASI platform support. 
This includes the following significant changes:
  * Patching ezsat and minisat to disable resource limiting code
    on WASM/WASI, since the POSIX functions they use are unavailable.
  * Adding a new definition, YOSYS_DISABLE_SPAWN, present if platform
    does not support spawning subprocesses (i.e. Emscripten or WASI).
    This definition hides the definition of `run_command()`.
  * Adding a new Makefile flag, DISABLE_SPAWN, present in the same
    condition. This flag disables all passes that require spawning
    subprocesses for their function.
