Geza Lore 7280307a39 Implement DPI import/export as loose functions 2021-06-13 15:06:28 +01:00
Geza Lore c207e98306
Implement a distinct constant pool (#3013) 
What previously used to be per module static constants created in
V3Table and V3Prelim are now merged globally within the whole model and
emitted as part of a separate constant pool. Members of the constant
pool are global variables which are declared lazily when used (similar to
loose methods).

Geza Lore 60d5f0e86b
Emit model implementation as loose methods. (#3006) 
This patch introduces the concept of 'loose' methods, which semantically
are methods, but are declared as global functions, and are passed an
explicit 'self' pointer. This enables these methods to be declared
outside the class, only when they are needed, therefore removing the
header dependency. The bulk of the emitted model implementation now uses
loose methods.

Geza Lore c67fe02f06 Do not generate debug info in tests 
Pointless and takes up a lot of cache space in CI, so remove -ggdb and
associated debug options from tests.

Add ccache-report target to standard Makefile (#3011) 
Using the standard model Makefile, when in addition to an explicit
target, the target 'ccache-report' is also given, a summary of ccache
hits/misses during this invocation of 'make' will be prited at the end
of the build.

Fix --protect-ids when using SV classes (#2994) 
A few names were incorrectly mangled, which made --protect-ids produce
invalid output when certain SV class constructs were uses. Now fixed and
added a few extra tests to catch this.

Improve Reloop to accept constant index offsets. (#2939) 
V3Reloop now can roll up indexed assignments between arrays if there is a
constant offset between indices on the left and right hand sides, e.g.:

a[0] = b[2];
a[1] = b[3];
...
a[x] = b[x + 2];

Stop checking dtype for better optimization chance in BitOpTree (#2909) 
* Tests: Add more case that does not match native C++ width (8, 16, 32 or 64).

* Use AstVarRef::same() instead of AstNode::sameGateTree() because the latter checks dtype in addition to scope.

AstVarRef may have different minWidth in some cases,
but the difference should be ignored in the context of bitOpTree optimization.

Support ignoring "`pragma protect ..." (#2886)

Allow overlaps in priority case statements (#2864) 
This will still warn if a case item is completely covered by previous
items, but will no longer complain about overlaps like this:

    priority casez (foo_i)
      2'b ?1: bar_o = 3'd0;
      2'b 1?: bar_o = 3'd1;

Before, there was a warning for the second statement because the first
two patterns match 2'b11.

**   Add context->time() and context->timeInc() API calls, to set simulation time.
      These now are recommended in place of the legacy sc_time_stamp().
