Subject: Why *l math functions are just skipped for some targets?
Hi,
files like __fpclassifyl.c omit implementation for corresponding
functions on platforms where sizeof(long double) == sizeof(double).
This is fine when musl is compiled at least with -O1 and compiler
omits calls to non-existing functions, but if one builds debug version
without optimizations, some executables end up having unresolved symbols
for functions like __fpclassifyl().
This causes some inconvenience. Also, optimizing compilers are not
intended to allow such hacks, it just happens to be so. Is there any
reason to not provide some stub functions? I can image small size is
the reason, but not sure it justifies unexpected unresolved symbols. At
least a comment in place of absent functions would be helpful.
Best regards,
Sergey
