Wanda 7f76914b74 Implement RFC 17: Remove log2_int. 
Reexports of `amaranth.utils` functions are removed from
`amaranth._utils` to avoid a circular import issue (for `deprecated`).
Since this is a private module, this should not be a problem.

Jaro Habiger c00e770f01 build.run: deprecate run_script argument in BuildPlan.execute_local() 2024-01-03 14:08:34 +00:00

Jaro Habiger 3200a3961d build.run: factor out extract method 2024-01-03 14:08:34 +00:00
Catherine 5d9ad62f36 build.plat,vendor: start build.sh with #!/bin/sh. 
The build scripts generated by Amaranth are designed to be invoked by
directly running them with any shell (some of them will re-invoke
themselves with `bash` specifically, when it's a toolchain requirement),
and they're not currently marked executable, so there's no shebang.

Add a shebang line to improve compatibility with cases where they are
treated as executables in their own right.

Marcelina Kościelnicka 8c4a15ab92 hdl.mem: lower Memory directly to $mem_v2 RTLIL cell. 
The design decision of using split memory ports in the internal
representation (copied from Yosys) was misguided and caused no end
of misery. Remove any uses of `$memrd`/`$memwr` and lower memories
directly to a combined memory cell, currently the RTLIL one.

Catherine a921261215 build.run: add env= argument to BuildPlan.execute_local(). 
Build scripts are explicitly intended to have overrides that are
done through the use of environment variables, and right now this
would require a very awkward `run_script=False` invocation followed
by copying a bit of code out of the Amaranth codebase, which is
clearly suboptimal.
