From 71e7e09092dc262b7cddbfc99e1b92e81ac58f21 Mon Sep 17 00:00:00 2001 From: Zachary Snow Date: Sat, 29 Oct 2022 15:14:11 -0400 Subject: verilog: Support module-scoped task/function calls This is primarily intended to enable the standard-permitted use of module-scoped identifiers to refer to tasks and non-constant functions. As a side-effect, this also adds support for the non-standard use of module-scoped identifiers referring to constant functions, a feature that is supported in some other tools, including Iverilog. --- frontends/ast/simplify.cc | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'frontends') diff --git a/frontends/ast/simplify.cc b/frontends/ast/simplify.cc index 49bf9af09..c932e2c49 100644 --- a/frontends/ast/simplify.cc +++ b/frontends/ast/simplify.cc @@ -3656,6 +3656,8 @@ skip_dynamic_range_lvalue_expansion:; goto apply_newNode; } + if (current_scope.count(str) == 0) + str = try_pop_module_prefix(); if (current_scope.count(str) == 0 || current_scope[str]->type != AST_FUNCTION) log_file_error(filename, location.first_line, "Can't resolve function name `%s'.\n", str.c_str()); } @@ -3727,6 +3729,8 @@ skip_dynamic_range_lvalue_expansion:; goto apply_newNode; } + if (current_scope.count(str) == 0) + str = try_pop_module_prefix(); if (current_scope.count(str) == 0 || current_scope[str]->type != AST_TASK) log_file_error(filename, location.first_line, "Can't resolve task name `%s'.\n", str.c_str()); } -- cgit v1.2.3
