Failed to analyze file with synopsys package

[Chopper455]

I've downloaded old FP adder to test the synthesis, it uses synopsys packages. So I've run synthesis in yosys + module.so mode. Command: ghdl --ieee=synopsys -fexplicit fpadd_normalize_struct.vhd -e FPadd_normalize

The output is:

2. Executing GHDL. ERROR: vhdl import failed.

without explicit flag it seems to see all the syntax, the output is:

1. Executing GHDL. fpadd_normalize_struct.vhd:145:56:error: operator ""="" is overloaded fpadd_normalize_struct.vhd:145:56:error: possible interpretations are: ../../src/synopsys/std_logic_unsigned.vhdl:64:14:error: function "=" [std_logic_vector, std_logic_vector return boolean] ../../src/ieee/v93/std_logic_1164.vhdl:90:8:error: function "=" [std_logic_vector, std_logic_vector return boolean] fpadd_normalize_struct.vhd:145:56:error: (you may want to use the -fexplicit option) fpadd_normalize_struct.vhd:148:59:error: operator ""/="" is overloaded fpadd_normalize_struct.vhd:148:59:error: possible interpretations are: ../../src/synopsys/std_logic_unsigned.vhdl:68:14:error: function "/=" [std_logic_vector, std_logic_vector return boolean] ../../src/ieee/v93/std_logic_1164.vhdl:90:8:error: function "/=" [std_logic_vector, std_logic_vector return boolean] ERROR: vhdl import failed.

I definitely remember that i synthesized long ago in some commercial product.

Now fixed. If you have test vectors, that would be very nice!
