symfpu: Verifying rounding modes 
Works for everything but muladd.
Which I saw coming, but am still frustrated by.

Including tests, but currently only testing rounding modes on multiply.
Also missing the ...01 case.

Merge pull request #5935 from YosysHQ/cat/cmake-macos 
CMake: improve macOS Homebrew compatibility
 2026-06-05 18:28:22 +00:00
Catherine 39ecd0d93f CMake: specify Flex and Bison version requirements. 
macOS ships Bison 2.6, which is too old for Yosys.
 2026-06-05 17:59:23 +00:00
Catherine d50dc9a461 CMake: add all Homebrew packages to root search path. 
Homebrew doesn't provide a merged (FHS) prefix and tools installed from
it cannot be expected to appear on PATH. Furthermore, XCode provides
some tools and headers (Flex, Bison) which must not be used if
a Homebrew alternative is installed.
 2026-06-05 17:58:29 +00:00
Catherine c9e3ae8c9a CMake: improve and vendor upstream `FindBISON` module. 
This change uses the `find_program(VALIDATOR)` functionality available
since CMake 3.25 to find the acceptable Bison executable instead of
failing if the first one found is too old. (macOS ships with Bison 2.6.)

This change also explicitly finds a usable M4 and ensures the Bison
command will use it. (macOS ships with an m4 which can fail if XCode
Tools aren't installed.)

docs: Resolving todos 
Make explicit the location for the `CMakeUserPresets.json` file.
Update docs tests documentation.
Move `BUILD_DIR` and `PROGRAM_PREFIX` comments into the functional tests todo.
Add cmake to MacPorts/FreeBSD install instructions.
Add ccache to example `CMakeUserPresets.json` (it isn't otherwise documented, and is no longer as obvious without an `ENABLE_CCACHE` makevar).

CMake: Add wrapper for test-docs 
Also skip calling `tail` on stubnets log outputs.

Fix auxprog prefixes

i.e. if we've set `YOSYS_PROGRAM_PREFIX=why`, we shouldn't be trying to call `build/yosys` when building docs (because if we've done a clean build it doesn't exist).
I suspect this also affects tests, but I was working on docs when I noticed it.

docs: Remove build dir from tool help 
Pipes the help through sed for the tools that include the path.  Also means we can drop the `|| true` from abc, since we're now reading the sed return instead.

register.cc: Make cmd paths proximate 
The CMake refactor changes relative paths to absolute when calling `source_location::current()`.  Use the path to `register.cc` to find the root yosys dir, and use that as the base for other paths.
Includes provisions for when plugins have a valid location; if it's not in the yosys source tree we shouldn't try to make the path relative, and we shouldn't try to auto group by path (since such groups will never be allocated, leaving them as unknown is preferable).
Limited to non wasm (I think that's the only one where we can't (easily) use `<filesystem>`). But where we do use `<filesystem>` we can also simplify the auto group to use `fs::path::parent_path()`.

Migrate build system to CMake
 2026-06-03 09:31:46 +00:00
Catherine afc0e78d11 Update top-level Python project for CMake compatibility. 
This commit reimplements the (no longer recommended) setuptools based
build system using a standards-based in-tree PEP517 build backend.
The implementation is partially based on
  https://codeberg.org/ziglang/zig-pypi/src/branch/main/make_wheels.py
which is licensed under BSD-0-clause.

It also adds a new option `YOSYS_BUILD_PYTHON_ONLY` that is available
only if the binary or the library aren't going to be installed, which
turns off these targets entirely, as well as some dependent ones
(e.g. tests).
