* Port nextpnr-{ice40,ecp5} to WASI.whitequark2020-05-231-6/+15
| | | | | | | | | | | | | | | | | | | | | 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.

* More adjustments to .bba file locationsLarry Doolittle2020-01-141-1/+1
| | | | | | | | | | Follows PM discussion with Marcus Comstedt. Extend changes in .bba file location (made in commit b6a7b60) to ice40 and MSVC cases, so all cases become compatible with read-only access to git tree. Only known down-side is inefficiency when building out-of-tree for multiple architectures; people following that use case should consider using PREGENERATED_BBA_PATH. It would be nice if there were less copy-paste in MSVC vs. non-MSVC content in family.cmake, but that would have to be addressed by someone more skilled in Cmake and MSVC.
* Remove barrier to out-of-tree buildsLarry Doolittle2020-01-121-2/+1
| | | | | With this change, nextpnr can build successfully (and run correctly) using the git tree as a read-only reference. No change in behavior observed for in-tree builds.

| | | | | | | | | | | | | | | | | | | | | | If a distro-specific "trellis-devel" package is used, the pytrellis.so library might be located in a dedicated directory, rather than under TRELLIS_ROOT. Search for pytrellis.so in a list of directories, then subsequently use the first match as part of PYTHONPATH. Signed-off-by: Gabriel Somlo <gsomlo@gmail.com>
