Icarus 0.8.3 seems to have problems with a literal expression in a
conditional statement:
module test;
initial
main;
task main;
begin
if(2)
$write("taken 'if' branch\n");
else
$write("taken 'else' branch\n");
end
endtask
endmodule
This (machine-generated) code takes the else branch, and not the if
branch. iverilog seems to be checking just the bottom bit of the
conditional; 'if(3)' works Ok.
This code segfaults on compilation:
module test;
initial
main;
task main;
begin
if(1)
;
end
endtask
endmodule
