* Fix a couple of compiler warnings (#62)Anton Blanchard2019-10-141-3/+3
| | | | | | | | | | | | | | | | | I see a few compiler warnings on gcc 9.2: src/ghdl.cc: In function ‘Yosys::RTLIL::SigSpec get_src(std::vector<Yosys::RTLIL::Wire*>&, GhdlSynth::Net)’: src/ghdl.cc:123:43: warning: ‘valzx’ may be used uninitialized in this function [-Wmaybe-uninitialized] 123 | switch(((val01 >> i)&1)+((valzx >> i)&1)*2) | ~~~~~~~^~~~~ src/ghdl.cc:123:26: warning: ‘val01’ may be used uninitialized in this function [-Wmaybe-uninitialized] 123 | switch(((val01 >> i)&1)+((valzx >> i)&1)*2) | ~~~~~~~^~~~~ src/ghdl.cc:99:26: warning: ‘val’ may be used uninitialized in this function [-Wmaybe-uninitialized] 99 | bits[i] = (val >> i) & 1 ? RTLIL::State::S1 : RTLIL::State::S0; | ~~~~~^~~~~ These both appear to be spurious, but initialize them to 0 to avoid the warning.
