nissy-core/src/utils/math.h, branch masterThe "engine" of nissy, including the H48 optimal solver.https://git.tronto.net/nissy-core/atom?h=master2026-04-06T13:55:33ZMake the project build with Microsoft's broken C compiler.2026-04-06T13:55:33ZSebastiano Trontosebastiano@tronto.net2026-04-06T13:55:33Zurn:sha1:fc41f7917531693680b5baf71ffe38c47333fe84
MSVC is not fully C11-compliant, even when compiling with /std:c11.
Some changes were needed to make the codebase compatible. Notably, the
notation a[static N] and a[n] for function parameters of array type is
not supported, so that had to be hidden behind a macro. Atomic types
are also an experimental feature, apparently, but at least they work
with the correct compiler flag.
One thing that MSVC does well, however, is warning on integer conversions
on /W4 level. I am not sure if Clang and GCC have something similar,
so I took this chance to fix some of these.

I found out that this gives undefined behavior when then size is 0.
Better not to have it at all, it is confusing for other developers anyway.

- Simplified logger to accept only a string, not a variadic list
of args like printf(). This can still use some improvement,
but now it is easier to use from other languages.
- Fixed some misuses of the logger (wrong types etc)
- Renamed some constants
- Fixed some typos in comments.
