Error when using function signature in report statement

[tmeissner]

When a function signature is used in a report statement, nvc emits an error like this:

** Error: ambiguous use of name WAIT_LEVEL
    > test.vhd:23
    |
  6 |   procedure wait_level(signal    data   : in std_logic;
    |   ^ hidden declaration of WAIT_LEVEL as WAIT_LEVEL [STD_LOGIC, STD_LOGIC, TIME]
 ...
 10 |   procedure wait_level(signal    data   : in std_logic_vector;
    |   ^ visible declaration of WAIT_LEVEL as WAIT_LEVEL [STD_LOGIC_VECTOR, STD_LOGIC_VECTOR, TIME]
 ...
 19 |   procedure wait_level(signal    data   : in std_logic;
    |   ^ visible declaration of WAIT_LEVEL as WAIT_LEVEL [STD_LOGIC, STD_LOGIC, TIME]
 ...
 23 |     report wait_level[std_logic, std_logic, time]'instance_name & " timeout occurred";
    |            ^^^^^^^^^^ use of name WAIT_LEVEL here
** Error: unexpected [ while parsing report statement, expecting one of **, severity or ;
    > test.vhd:23
    |
 23 |     report wait_level[std_logic, std_logic, time]'instance_name & " timeout occurred";
    |                      ^ this token was unexpected

The first error is a subsequent error from the fact that nvc can't distinguish between the two function of same name. For that reason I give the signature of the function in line 23, however nvc can't parse that code.

Thanks for fixing this 👍
