- For
- HolyC and low-level compiler enthusiasts
- Worth noticing
- The page reports a four-function test producing 1,904 bytes, with an example covering SSE2 math and NaN replacement.
Field notes
The displayed HolyC program combines pointer aliasing and bit shifts, heap allocation, 64-bit integer arithmetic, and floating-point processing in one compiler showcase. For the floating-point case, the page says the compiler emits IEEE-754 NaN checks and SSE2 operations; these are project claims presented alongside the example, not independently verified here. The author says the source tree is being cleaned before a GitHub release.
