Remove compiler and cpp_std from `build-yosys` matrix. Using `config-$CC` will instead fall back to default values.
Drop `Tool versions` step and introduce `yosys-config` output instead.
Rename `test-builds` to `test-compile`.
`os_name` in include section needs to be explicit (putting it at the end doesn't
apply to the extra jobs).
Move macOS test to extra job instead of doing all gcc/clang (which isn't setup
for mac anyway).
Also adds name to build-yosys task.
Switch build artifact to a default clang build.
Testing with the build artifact locally, `make test` is failing with `/lib/x86_64-linux-gnu/libstdc++.so.6: version 'GLIBCXX_3.4.29' not found`. Using the gcc-11 build (might be?) installing GLIBCXX_3.4.29 but not linking it into the build. Rather than trying to get it to link, just use the pre-installed `clang` instead.
Separates `test-linux` into `build-linux` and `test-linux`, wherein `build-` builds out of tree, and uploading the build for the `test-` job.
Tar compression is done to retain execution permissions when downloading build artifact.
When calling `make test`, override `TARGETS` and `EXTRA_TARGETS` to prevent rebuild.
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.
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.
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%.
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.
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.
