Module Name: src
Committed By: riastradh
Date: Thu May 9 12:23:21 UTC 2024
Modified Files:
src/tests/lib/libm: t_ilogb.c
Log Message:
tests/lib/libm/t_ilogb: Expand and tidy.
1. Instead of calling out VAX by name, use #ifdef NAN and
isinf(INFINITY). (VAX defines INFINITY even though it's not an
infinity, not sure if there's a better compile-time test.)
2. Verify ilogbl works on long double on all architectures, not just
those with __HAVE_LONG_DOUBLE which means long double is _larger_
than double.
