* use eigen as an IMPORTED target in CMakeDan Callaghan2023-01-241-2/+1
| | | | | | | | | | Eigen considers the EIGEN3_INCLUDE_DIRS and EIGEN3_DEFINITIONS variables to be deprecated and they will no longer be exported in the next release after 3.4.0: https://gitlab.com/libeigen/eigen/-/commit/f2984cd0778dd0a1d7e74216d826eaff2bc6bfab Use the IMPORTED target instead, which seems to be the preferred way of consuming third-party CMake libraries.

* Add CMake option to enable IPO (enabled by default).William D. Jones2021-04-071-2/+13
|
* Initial lookahead for FPGA interchange.Keith Rothman2021-03-231-0/+7
| | | | | | | | | Currently the lookahead is disabled by default because of the time to compute and RAM usage. However it does appear to work reasonably well in testing. Further effort is required to lower RAM usage after initial computation, and explore trade-off for cheaper time to compute. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>

* CMake: Don't include Abseil if it is not used.whitequark2021-03-121-1/+3
|
* Only depend on Abseil in threaded builds.whitequark2021-03-101-2/+4
| | | | | | Abseil has a hard dependency on threads (not just in the build system but in many places in the base libraries), so there is no way to use it on WASI at the moment.
* Add absl::flat_hash_map.Keith Rothman2021-03-011-0/+5
| | | | | | | This lowers the CPU cost of using the flat wire map in router2, and should use less memory as well. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>

* cmake: Enable -Wextra, and -Werror in some casesgatecat2021-02-251-3/+8
| | | | | | -Werror is not enabled by default, except on CI and for a few specific common traps, to avoid the inevitable breakages when new compiler versions add new diagnostics. Signed-off-by: gatecat <gatecat@ds0.me>

| * Port nextpnr-{ice40,ecp5} to WASI.whitequark2020-05-231-2/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
