prefix of array attribute must be an object name #1152
Description
The MWE below is extracted from VUnit/vunit#631. Since a few days ago, the MWE fails during analysis:
test.vhd:14:54:error: prefix of array attribute must be an object name
ghdl:error: compilation error
I think it might be a regression, since the same code has worked for many months. Moreover, if the commented ret_range and ret_val are used instead, the MWE works as expected.
How to reproduce?
entity ent is
end;
architecture arch of ent is
type range_t is array (integer range <>) of bit;
function get_range (constant code : string) return range_t is
constant ret_val : range_t(1 to 10) := (others => '0');
begin
return ret_val;
end function get_range;
signal ret_val : boolean_vector(get_range("HELLO")'range) := (others => false);
--constant ret_range : range_t := get_range("HELLO");
--signal ret_val : boolean_vector(ret_range) := (others => false);
begin
end;ghdl -a --std=08 ent.vhd
