2019-09-05Improve PRNG jumping when using threadsJanne Blomqvist2-27/+32
Currently, when a new thread needs to use the RANDOM_NUMBER intrinsic, the per-thread PRNG state is initialized by copying the master state and then jumping forwards N*2**128 entries in the stream so that the PRNG streams for different threads don't alias each other, where N is the number of threads that have so far initialized the PRNG. With this patch the master state itself is jumped forwards once each time a new thread initializes the PRNG, thus obviating the need to jump through all the N-1 previous streams. Effectively turning an O(N) algorithm into an O(1) one. Regtested on x86_64-pc-linux-gnu. libgfortran/ChangeLog: 2019-09-05 Janne Blomqvist <jb@gcc.gnu.org> * intrinsics/random.c (master_init): Replace with master_state.init. (njumps): Remove variable. (master_state): Make instance of struct prng_state. (init_rand_state): When jumping, update the master_state once instead of keeping track of how many jumps need to be done.

Update the PRNG from xorshift1024* to xoshiro256** by the same author. For details see http://prng.di.unimi.it/ and the paper at https://arxiv.org/abs/1805.01407 Also the seeding is slightly improved, by reading only 8 bytes from the operating system and using the simple splitmix64 PRNG to fill in the rest of the PRNG state (as recommended by the xoshiro author), instead of reading the entire state from the OS.

As the static backtrace state pointer can be accessed from multiple threads, use atomics to access it.

2018-11-30Initialize backtrace state onceJanne Blomqvist2-4/+14
From backtrace.h for backtrace_create_state: Calling this function allocates resources that can not be freed. There is no backtrace_free_state function. The state is used to cache information that is expensive to recompute. Programs are expected to call this function at most once and to save the return value for all later calls to backtrace functions. So instead of calling backtrace_create_state every time we wish to show a backtrace, do it once and store the result in a static variable. libbacktrace allows multiple threads to access the state, so no need to use TLS.
