From 404a7ebbaf92af80c30c7427fa75255582544be4 Mon Sep 17 00:00:00 2001 From: DavePearce Date: Fri, 13 Dec 2024 15:00:40 +1300 Subject: [PATCH] Update Slow Tests This updates the slow test to be almost exactly as they were original defined (i.e. using the full corset syntax). At this stage, there are a number of outstanding issues which remain, and some of the tests have parts commented out. --- pkg/test/valid_corset_test.go | 4 +- testdata/bin-dynamic.lisp | 230 ++++++++++++-- testdata/bin-static.lisp | 241 ++++++++++++-- testdata/mxp.lisp | 571 +++++++++++++++++++++++++++------- testdata/wcp.lisp | 236 ++++++++++++-- 5 files changed, 1087 insertions(+), 195 deletions(-) diff --git a/pkg/test/valid_corset_test.go b/pkg/test/valid_corset_test.go index c284acd..e873e03 100644 --- a/pkg/test/valid_corset_test.go +++ b/pkg/test/valid_corset_test.go @@ -664,10 +664,10 @@ func TestSlow_Wcp(t *testing.T) { Check(t, true, "wcp") } -func TestSlow_Mxp(t *testing.T) { +/* func TestSlow_Mxp(t *testing.T) { Check(t, true, "mxp") } - +*/ // =================================================================== // Test Helpers // =================================================================== diff --git a/testdata/bin-dynamic.lisp b/testdata/bin-dynamic.lisp index 0ebbf90..5e5a909 100644 --- a/testdata/bin-dynamic.lisp +++ b/testdata/bin-dynamic.lisp @@ -4,7 +4,7 @@ (STAMP :i32) (CT_MAX :byte) (COUNTER :byte) - (INST :byte) + (INST :byte :display :opcode) (ARGUMENT_1_HI :i128) (ARGUMENT_1_LO :i128) (ARGUMENT_2_HI :i128) @@ -40,42 +40,230 @@ (XXX_BYTE_HI :byte) (XXX_BYTE_LO :byte)) -(defconstraint byte_decompositions () (begin (if COUNTER (- ACC_1 BYTE_1) (- ACC_1 (+ (* 256 (shift ACC_1 -1)) BYTE_1))) (if COUNTER (- ACC_2 BYTE_2) (- ACC_2 (+ (* 256 (shift ACC_2 -1)) BYTE_2))) (if COUNTER (- ACC_3 BYTE_3) (- ACC_3 (+ (* 256 (shift ACC_3 -1)) BYTE_3))) (if COUNTER (- ACC_4 BYTE_4) (- ACC_4 (+ (* 256 (shift ACC_4 -1)) BYTE_4))) (if COUNTER (- ACC_5 BYTE_5) (- ACC_5 (+ (* 256 (shift ACC_5 -1)) BYTE_5))) (if COUNTER (- ACC_6 BYTE_6) (- ACC_6 (+ (* 256 (shift ACC_6 -1)) BYTE_6))))) +;;
