Jannis Harder d8687e87b1 kernel: Avoid including files outside include guards
This adjusts the way the headers kernel/{yosys,rtlil,register,log}.h
include each other to avoid the need of including headers outside of
include guards as well as avoiding the inclusion of rtlil.h in the
middle of yosys.h with rtlil.h depending on the prefix of yosys.h, and
the suffix of yosys.h depending on rtlil.h.

To do this I moved some of the declaration in yosys.h into a new header
yosys_common.h. I'm not sure if that is strictly necessary.

Including any of these files still results in the declarations of all
these headers being included, so this shouldn't be a breaking change for
any passes or external plugins.

My main motivation for this is that ccls's (clang based language server)
include guard handling gets confused by the previous way the includes
were done. It often ends up treating the include guard as a generic
disabled preprocessor conditional, breaking navigation and highlighting
for the core RTLIL data structures.

Additionally I think avoiding cyclic includes in the middle of header
files that depend on includes being outside of include guards will also
be less confusing for developers reading the code, not only for tools
like ccls.

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.)

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.

Catherine 8388846e3a fmt,cxxrtl: add support for uppercase hex format.
This is necessary for translating Python format strings in Amaranth.

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.
