Hi, I have a little question Right now internally in gcc we flexibly check whether a particular function (or rather "function class", which could be easily extended) is present or not in libc by calling target hook "libc_has_function", however in the testsuite for c99 runtime we still check whether the full support of it is in place (in gcc.dg/builtins-config.h).
And so some tests for some targets (e.g. gcc.dg/builtins-58.c for bionic) are unsupported right now, while actually they are OK. I wonder may be we can somehow get the value of libc_has_function hook for a particular function in the test so to flexibly define whether the test should be unsupported or not? E.g. by adding some debug options for gcc that will return the result of the hook? But I doubt that such option would be a pretty solution thanks --Alexander
