    • Use urandom in gcc.c too · 44a22bdb 
      gcc also takes generates a random number in some special circumstances,
so teach it about /dev/urandom too.

gcc/:

2011-09-27   Andi Kleen <ak@linux.intel.com>

	* gcc.c (get_local_tick). Rename to get_random_number.
        Read from /dev/urandom.
	Add getpid call.
	(compare_debug_dump_opt_spec_function): Drop getpid call.

    • Use urandom to get random seed · 35f2a89d 
      When available use /dev/urandom to get the random seem. This will lower the probability
of collisions.

On other systems it will fallback to the old methods.

Passes bootstrap + testsuite on x86_64. Ok?

    • Change random seeds to 64bit and drop re-crcing · dde8b360 
      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.

      The commands of the $(TOOLS_ZIP) rule include copying of two subtrees from the source tree (asm/ and classes/).

The commands of the $(TOOLS_ZIP) rule include copying of two subtrees from the
source tree (asm/ and classes/). If the source tree is read-only, the use of
cp's -p option here prevents the trees from getting deleted later in the rule
if they (or at least their directories) don't get marked writable.

Committed as obvious.
