From 53018dc2bcd0f0ee65ca9c869130ec0e56da63e2 Mon Sep 17 00:00:00 2001 From: Jens Reidel Date: Fri, 25 Jul 2025 01:45:42 +0000 Subject: Disable has_reliable_f128_math on musl targets musl does not implement the symbols required by std for f128 maths. Disable the associated cfg for all musl targets and adjust the tests accordingly.
