search for: __acosf_finite

...have no trouble finding every other libc / libm / libc++ / ... symbol so I assumed that it was not necessary to specifically link against libm where these __finite symbols reside: $ nm -D /usr/lib/libm.so.6 | grep finite 0000000000050540 T __acosf128_finite at GLIBC_2.26 0000000000042f70 T __acosf_finite at GLIBC_2.15 0000000000026940 i __acos_finite at GLIBC_2.15 0000000000051000 T __acoshf128_finite at GLIBC_2.26 0000000000043240 T __acoshf_finite at GLIBC_2.15 ) but maybe it needs some help on that regard ?

Hello, when building code with -Ofast -ffinite-math-only -ffast-math, clang generates calls to "finite" variants of math functions. This has been the source of a fair amount of issues in a "normal", non-JIT pipeline, which seem to have been fixed over time - a simple fix being recompiling the target app against the new glibc. - https://bugs.llvm.org/show_bug.cgi?id=44842 -
