2011-09-29Change random seeds to 64bit and drop re-crcingAndi Kleen11-27/+56
I had some trouble with random build failures in a large LTO project and it turned out to be random seed collisions in a highly parallel build (thanks to Honza for suggesting that) There were multiple problems: - The way to generate the random seed is not very random (milliseconds time plus pid) and prone to collisions on highly parallel builds - It's only 32bit - Several users take the existing ascii seed and re-CRC32 it again, which doesn't exactly improve it. This patch changes that to: - Always use 64bit seeds as numbers (no re-crcing) - Change all users to use HOST_WIDE_INT - When the user specifies a random seed it's still crc32ed, but only in this case. Passes bootstrap + testsuite on x86_64-linux. gcc/cp: 2011-09-26 Andi Kleen <ak@linux.intel.com> * repo.c (finish_repo): Use HOST_WIDE_INT_PRINT_HEX_PURE. gcc/: 2011-09-26 Andi Kleen <ak@linux.intel.com> * hwint.h (HOST_WIDE_INT_PRINT_HEX_PURE): Add. * lto-streamer.c (lto_get_section_name): Remove crc32_string.
