| * | Add WASI platform support.whitequark2020-04-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This includes the following significant changes: * Patching ezsat and minisat to disable resource limiting code on WASM/WASI, since the POSIX functions they use are unavailable. * Adding a new definition, YOSYS_DISABLE_SPAWN, present if platform does not support spawning subprocesses (i.e. Emscripten or WASI). This definition hides the definition of `run_command()`. * Adding a new Makefile flag, DISABLE_SPAWN, present in the same condition. This flag disables all passes that require spawning subprocesses for their function.

| * Improved rewrite code for writing to bit slice (disabled for now)Claire Wolf2020-04-151-12/+64
| | | | | | | | | | | | | | | | | | This adds the new rewrite rule. But it's still missing a check that makes sure the new rewrite rule is actually a valid substitute in the always block being processed. Therefore the new rewrite rule is just disabled for now.

| * | ast, rpc: record original name of $paramod\* as \hdlname attribute.whitequark2020-04-182-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The $paramod name mangling is not invertible (the \ character, which separates the module name from the parameters, is valid in the module name itself), which does not stop people from trying to invert it. This commit makes it easy to invert the name mangling by storing the original name explicitly, and fixes the firrtl backend to use the newly introduced attribute.

| * ast/simplify: improve enum handling.whitequark2020-04-151-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, enum values were serialized as attributes of form \enum_<width>_<value> where <value> was a decimal signed integer. This has multiple drawbacks: * Enums with large values would be hard to process for downstream tooling that cannot parse arbitrary precision decimals. (In fact Yosys also did not correctly process enums with large values, and would overflow `int`.) * Enum value attributes were not confined to their own namespace, making it harder for downstream tooling to enumerate all such attributes, as opposed to looking up any specific value. * Enum values could not include x or z, which are explicitly permitted in the SystemVerilog standard. After this commit, enum values are serialized as attributes of form \enum_value_<value> where <value> is a bit sequence of the appropriate width.

| | | | | | | | | | | | | | | | | | | | | (parameters in systemverilog packages can't actually be overridden, so allowing parameters in addition to localparams doesn't actually add any new functionality, but it's useful to be able to use the parameter keyword also)
