whitequark e91a5ad934 _toolchain.cxx: ignore another deprecation warning (on Python 3.10). 
Sigh.

whitequark 3379f072a0 _toolchain.cxx: ignore deprecation warning (on Python 3.6). 
This code really shouldn't be using distutils, but for now this will
have to do.

whitequark 369cc59d69 docs: update requirements. 
Sphinx 4.2 or later is required for compatibility with Python 3.10.

A released version of Pygments can now be used for highlighting.

whitequark 8081df1265 _toolchain.cxx: use distutils from setuptools. 
The distutils module from the standard library is deprecated and will
be removed in Python 3.12, and PEP 632 recommends using
distutils.ccompiler from setuptools, instead.

This code should eventually be rewritten to use zig-pypi, but for now
this suffices.

whitequark 11914a1e67 hdl.ast: improve interaction of ValueCastable with custom __getattr__. 
Avoid calling `__getattr__("_ValueCastable__lowered_to")` when
a ValueCastable has custom `__getattr__` implementation; this avoids
the need for downstream code to be aware of this implementataion
detail.

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, Virtex E (also known as Spartan 2, Spartan 2E)
- Virtex 2, Virtex 2 Pro
- Spartan 3, Spartan 3E (in addition to existing Spartan 3A, Spartan 3A
  DSP support)
- Virtex 4
- 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. 
This was an especially insidious bug because the minus character is
valid in case values but has a completely different meaning (wildcard
rather than sign).
