* Remove wire alias APIDavid Shah2020-10-151-2/+0
| | | | | | It has not actually been implemented in any router for over 2.5 years and causes nothing more than confusion. It can always be added back if it forms part of a future solution; possibly as part of a more general database structure rethink. Signed-off-by: David Shah <dave@ds0.me>

| | | | | | | In order to make debugging the critical path easier, add an option that will log the location each net was defined, if known. If the file that contains the definition is known, and is readable, also print the part of the source HDL responsible for the signal definition.

| * Port nextpnr-{ice40,ecp5} to WASI.whitequark2020-05-234-8/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This involves very few changes, all typical to WASM ports: * WASM doesn't currently support threads or atomics so those are disabled. * WASM doesn't currently support exceptions so the exception machinery is stubbed out. * WASM doesn't (and can't) have mmap(), so an emulation library is used. That library currently doesn't support MAP_SHARED flags, so MAP_PRIVATE is used instead. There is also an update to bring ECP5 bbasm CMake rules to parity with iCE40 ones, since although it is possible to embed chipdb into nextpnr on WASM, a 200 MB WASM file has very few practical uses. The README is not updated and there is no included toolchain file because at the moment it's not possible to build nextpnr with upstream boost and wasi-libc. Boost requires a patch (merged, will be available in boost 1.74.0), wasi-libc requires a few unmerged patches.
