cxxrtl: reduce stack space used by the `debug_info()` function
 2024-05-08 05:48:29 +01:00
Catherine 6e003e1af6 cxxrtl: minimize stack space consumed by `debug_info()`. 
This commit uses parameter packs to sink `debug_item()` construction
into the `debug_info()`-specific `add()` overload. This makes the stack
space use sub-linear in typical case rather than linear (which is still
the worst case). Oddly, the stack slots that get allocated now are all
for the `0` literal for `lsb_offset`. This could be fixed by allocating
numbers statically but the existing reduction in stack use of ~98% for
a representative example (Minerva SoC) should be enough.

Catherine 80798daf53 cxxrtl: reduce stack space consumed by `debug_info()` further. 
Before this commit, this function would create a temporary `std::string`
per debug item (and scope). After this commit, an additional overload is
used to push that down the call stack. This reduces stack usage by
about 50% more on top of the previous commit.

Catherine 9134cd1928 cxxrtl: reduce stack space consumed by `debug_info()`. 
Before this commit, the creation of (constant) attribute maps caused
`debug_info()` (which is built with `__attribute__((optnone))`) to
consume large amounts of stack space; up to tens of megabytes. This
caused problems particularly on macOS, where the default stack size
is 512 KiB.

After this commit, `std::map` objects are no longer created inline in
the `debug_info()` function, but are compiled to and then expanded from
a string literal in a subroutine call. This reduces stack space usage
by about 50%.

Catherine 43ddd89ba5 cxxrtl: fix `escape_c_string` hex literal fiasco. 
In C and C++, a `\x` escape sequence consumes as many hexadecimal digits
as there are available, so it is not composable with arbitrary alnum
characters afterwards. An octal escape sequence like `\000` always has
fixed width, avoiding an issue where `\x01c` and `\x1c` produce the same
string.

Jannis Harder a52088b6af smtbmc: Improvements for --incremental and .yw fixes 
This extends the experimental incremental JSON API to allow arbitrary
smtlib subexpressions, defining smtlib constants and to allow access of
signals by their .yw path.

It also fixes a bug during .yw writing where values would be re-emitted
in later cycles if they have no newer defined value and a potential
crash when using --track-assumes.
