I contend that the cross build still loops for ppc64el. It kinda feels like a different issue though. Should we close this one and open a new one or retitle? The issue is with the detection of the long double epsilon on powerpc architectures. m4/floatparam.m4' macro CL_FLOATPARAM_CROSS attempts to deduce the minimal value that can be added to 1 using compile time bisection. That works, because gcc does constant folding of floating point numbers, except when it does not not powerpc architectures. There is a long standing gcc bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=19779. Would there be any chance to use gcc constants such as LDBL_EPSILON for this case (even opportunistically)? In any case, the current implementation is very bad, because the while loop never finishes as every compilation attempt fails on the supposedly non-constant expression. At minimum, there should be a bound on the number of iterations. Helmut
