[Iverilog-devel] Subdividing the ivtest compiler regression test lists

[Martin W. <mai...@ma...>]

I suggested this a while ago, but have now got round to trying it. Rather than 
have a single regress.list, I've split it into a number of separate lists:

   regress-vlg.list      - tests that should work with any standard
                           Verilog (1364-2005) simulator
   regress-sv.list       - tests that should work with any standard
                           SystemVerilog (1800-2012) simulator
   regress-vhdl.list     - tests that should work with any standard
                           VHDL simulator
   regress-vams.list     - tests that should work with any standard
                           Verilog-AMS simulator
   regress-ivl1.list     - tests that use Icarus Verilog extensions
                           or known deviations from the standard,
                           excluding those in regress-ivl2.list
   regress-ivl2.list     - tests that rely on lossless expressions
                           or on the default vvp unformatted real
                           number display
   regress-synth.list    - tests that exercise the Icarus Verilog
                           synthesis functionality
   regress-v0.9.list     - test exceptions for v0.9
   regress-v0.10.list    - test exceptions for v0.10
   regress-vlog95.list   - test exceptions for the vlog95 target

(I may not have put all the tests in their proper categories, but I think it's 
mostly right).

The main aim of this change is to reduce the effort needed to maintain the 
lists when adding tests that aren't supported by older versions of Icarus or 
by the vlog95 target. The scripts only load the test lists that are 
appropriate to the compiler version and target being exercised.

I've taken this opportunity to sort the main lists into alphabetic/numeric 
order and to make the tabulation more consistent (and hopefully more readable).

I've pushed these new lists, plus two modified scripts, new_vvp_reg.pl and 
new_vlog95_reg.pl, to the ivtest master branch. The original regress.list and 
perl scripts are still there, unmodified.

Take a look and let me know what you think.

P.S. I haven't created a test exception list for v0.8 - do we still want/need 
to support this?
