hdl.ast: remove quadratic time complexity in Statement.cast(). 
Using `sum(lst, [])` to flatten a list of lists has quadratic time
complexity. Use `chain.from_iterable()` instead. While not strictly
necessary to improve performance, convert to `map()`.

A test case writing out verilog for a 512k entry FIFO is 120x faster
with this applied.

vendor.xilinx: avoid using / for hierarchy in ISE constraint files. 2021-09-25 10:41:23 +00:00
Marcelina Kościelnicka bdbe8bff27 Unify Xilinx platforms into a single class, support more devices 
This merges existing code, and also adds support for:

- Virtex 5
- Virtex 6
- ISE synthesis for Series 7

Fixes #552.

Adam Jeliński da8a492be7 _toolchain: Properly set compiler/linker executables on Gentoo 
The `test_toolchain_cxx.py` tests on Gentoo definitely use compiler and
linker set with `_so_cxx`-suffixed executables. Tests use a proper
executable instead of `c++` after this change.

vendor.xilinx_7series: fix tool names for symbiflow. 
Prefix "tools" with symbiflow_ as is done for the QuickLogic Symbiflow
toolchain. Installing symbiflow gives me the tools with the preifx, so I
guess this is the correct way to move forward.

whitequark 818c8bc464 hdl.ast: normalize case values to two's complement, not signed binary.

valid in case values but has a completely different meaning (wildcard
rather than sign).

whitequark 36bc1d2b4d vendor.quicklogic: write OpenOCD scripts as part of build process.

hdl.rec: proxy operators correctly. 
Commit abbebf8e used __getattr__ to proxy Value methods called on 
Record. However, that did not proxy operators like __add__ because
Python looks up the special operator methods directly on the class
and does not run __getattr__ if they are missing.

Instead of using __getattr__, explicitly enumerate and wrap every
Value method that should be proxied. This also ensures backwards
compatibility if more methods are added to Value later.

Fixes #533.
