75ee2fc4e6 Move RelPtr/RelSlice out of arches into common 
The bba approach seems widely used enough that it's reasonable for this
to become part of common code.

3fc5455ec5 ecp5: Switch from RelPtr to RelSlice 
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.

Update CMakeLists.txt 
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.

b18ea204c2 Remove wire alias API 
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.

f6e30f22f4 CMake: fix path checks in chipdb build scripts. 
`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
 2020-05-24 14:23:35 +01:00

e7bb04769d Port nextpnr-{ice40,ecp5} to WASI. 
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.
