develonepi3mmicko ZipCPU recommended that I ask you. I was able to build icestorm 8cac6c5840 with Yocto cross compiling for ARM on x86_64, but was seeing QA errors.  They don't recommend installing in /usr/local/.  I pulled the latest ver and now  missing binary operator before token "(" 133 | #if __HAVE_FLOAT16 && __GLIBC_USE (IEC_60559_TYPES_EXT). Any idea?22:23

gromerohi22:58
gromeroI'm getting a syntax error like: ERROR: syntax error, unexpected TOK_REG, expecting TOK_ID22:58
gromerobut it do can synthesize the .v file without any error22:59
gromerohttps://pastebin.com/raw/yfGg15yH22:59
gromeroany clue on what exactly the parser is requesting there?22:59
daveshah"bit" is a SystemVerilog keyword23:00
gromerooh!23:00
gromerodaveshah: thanks a lot. indeed :)23:01
gromeroso it means that for simulation ir's a SystemVerilog parser and for synthesis it's only the synthesizable subset of Verilog?23:03
gromeros/ir's/it's/23:03
daveshahYosys doesn't do significant simulation in the traditional sense, any sim it does do goes through the same elaboration/synth23:17
daveshahIt supports a subset of SystemVerilog features. bit as an alias for reg is one of them.23:18

ZirconiumXWell, cxxrtl makes it look a lot like Verilator23:30
gromerodaveshah: hrm but if it do goes through the same elaboration/synth, why the problematic code I've pasted do really synthetizes fine?23:32
daveshahZirconiumX: Yes that's why I said traditional sense - in the context of parsing23:32
daveshahgromero: but it doesn't you said there was an error23:33
ZirconiumXgromero: AIUI your code should parse fine without -sv23:35
ZirconiumXYou're not using anything actually SV in there23:35
daveshahIndeed, the problem is nothing to do with simulation or synthesis but SystemVerilog vs Verilog23:36
gromeroZirconiumX: daveshah ah got it. thanks :)23:37
