Fangrui Song 25f74087c6 util/cutils: Fix incorrect integer->float conversion caught by clang ... Clang does not like do_strtosz()'s code to guard against overflow: qemu/util/cutils.c:245:23: error: implicit conversion from 'unsigned long' to 'double' changes value from 18446744073709550592 to 18446744073709551616 [-Werror,-Wimplicit-int-float-conversion] The warning will be enabled by default in clang 10. It is not available for clang <= 9. val * mul >= 0xfffffffffffffc00 is indeed wrong. 0xfffffffffffffc00 is not representable exactly as double. It's half-way between the representable values 0xfffffffffffff800 and 0x10000000000000000. Which one we get is implementation-defined. Bad. We want val * mul > (the largest uint64_t exactly representable as double). That's 0xfffffffffffff800. Write it as nextafter(0x1p64, 0) with a suitable comment.
