* cleanup: Remove dead/unused codeD. Shah2021-01-281-25/+0

* Move RelPtr/RelSlice out of arches into commonD. Shah2021-01-271-37/+1
| | | | | | | The bba approach seems widely used enough that it's reasonable for this to become part of common code. Signed-off-by: D. Shah <dave@ds0.me>
* ecp5: Switch from RelPtr to RelSliceD. Shah2021-01-273-165/+143
| | | | | | | | | | This replaces RelPtrs and a separate length field with a Rust-style slice containing both a pointer and a length; with bounds checking always enforced. Thus iterating over these structures is both cleaner and safer. Signed-off-by: D. Shah <dave@ds0.me>

* Update CMakeLists.txtYehowshua Immanuel2020-11-171-1/+1
| | | | | I believe Prjtrellis has CMAKE define pytrellis as a shared module, not library. On MacOS, this makes a difference and NextPNR expected ``.dylib`` instead of ``.so``. Things still work on Linux.

* RelPtr: remove copy constructor and copy assignmentDavid Shah2020-11-131-0/+3
| | | | | | | These operations are meaningless for a data structure that references another structure relative to its location. Signed-off-by: David Shah <dave@ds0.me>

* Remove wire alias APIDavid Shah2020-10-151-9/+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>

| | | | | | | | | | | | | | `if(NOT DEFINED)` is not appropriate since a variable that contains `-NOTFOUND` still counts as `DEFINED`. This can cause issues if configuration fails, writes `-NOTFOUND` to the cache, and is then restarted.

| * Port nextpnr-{ice40,ecp5} to WASI.whitequark2020-05-232-8/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
