Catherine d9a4a42389 write_verilog: don't `assign` to a `reg`. 
Fixes #2035.

Catherine cb07710162 write_verilog: only warn on processes with sync rules. 
Processes without sync rules correspond to simple decision trees that
directly correspond to `always @*` or `always_comb` blocks in Verilog,
and do not need a warning.

This removes the need to suppress warnings during the RTLIL-to-Verilog
conversion performed by Amaranth.

Catherine 94170388a9 fmt: if enabled, group padding zeroes. 
Before this commit, the combination of `_` and `0` format characters
would produce a result like `000000001010_1010`.
After this commit, it would be `0000_0000_1010_1010`.

This has a slight quirk where a format like `{:020_b}` results in
the output `0_0000_0000_1010_1010`, which is one character longer than
requested. Python has the same behavior, and it's not clear what would
be strictly speaking correct, so Python behavior is implemented.

Catherine 27cb4c52b4 fmt: allow padding characters other than `'0'` and `' '`. 
When converted to Verilog, padding characters are replaced with one of
these two. Otherwise padding is performed with exactly that character.

Catherine ddf7b46955 fmt,cxxrtl: fix printing of non-decimal signed numbers. 
Also fix interaction of `NUMERIC` justification with `show_base`.
 2024-04-02 12:13:22 +02:00
Catherine 00c5b60dfd fmt,cxxrtl: add option to group digits in numbers. 
The option is serialized to RTLIL as `_` (to match Python's option with
the same symbol), and sets the `group` flag. This flag inserts an `_`
symbol between each group of 3 digits (for decimal) or four digits (for
binary, hex, and octal).
 2024-04-02 12:13:22 +02:00
Catherine 7b94599162 fmt,cxxrtl: add option to print numeric base (`0x`, etc). 
The option is serialized to RTLIL as `#` (to match Python's and Rust's
option with the same symbol), and sets the `show_base` flag. Because
the flag is called `show_base` and not e.g. `alternate_format` (which
is what Python and Rust call it), in addition to the prefixes `0x`,
`0X`, `0o`, `0b`, the RTLIL option also prints the `0d` prefix.

Catherine bf5a960668 fmt,cxxrtl: add `UNICHAR` format type. 
This format type is used to print an Unicode character (code point) as
its UTF-8 serialization. To this end, two UTF-8 decoders (one for fmt,
one for cxxrtl) are added for rendering. When converted to a Verilog
format specifier, `UNICHAR` degrades to `%c` with the low 7 bits of
the code point, which has equivalent behavior for inputs not exceeding
ASCII. (SystemVerilog leaves source and display encodings completely
undefined.)

Catherine 1780e2eb1e fmt,cxxrtl: add support for `NUMERIC` justification. 
Before this commit, the existing alignments were `LEFT` and `RIGHT`,
which added the `padding` character to the right and left just before
finishing formatting. However, if `padding == '0'` and the alignment is
to the right, then the padding character (digit zero) was added after
the sign, if one is present.

After this commit, the special case for `padding == '0'` is removed,
and the new justification `NUMERIC` adds the padding character like
the justification `RIGHT`, except after the sign, if one is present.
(Space, for the `SPACE_MINUS` sign mode, counts as the sign.)
 2024-04-02 12:13:22 +02:00
Catherine 6d6b138607 fmt,cxxrtl: support `{,PLUS_,SPACE_}MINUS` integer formats. 
The first two were already supported with the `plus` boolean flag.
The third one is a new specifier, which is allocated the ` ` character.
In addition, `MINUS` is now allocated the `-` character, but old format
where there is no `+`, `-`, or `-` in the respective position is also
accepted for compatibility.
 2024-04-02 12:13:22 +02:00
Catherine 8388846e3a fmt,cxxrtl: add support for uppercase hex format. 
This is necessary for translating Python format strings in Amaranth.
 2024-04-02 12:13:22 +02:00
Catherine a5441bc00c fmt: `FmtPart::{STRING→LITERAL},{CHARACTER→STRING}`. 
Before this commit, the `STRING` variant inserted a literal string;
the `CHARACTER` variant inserted a string. This commit renames them
to `LITERAL` and `STRING` respectively.
