2016-11-14Add jump functions to rand moduleKenji Rikitake
Jump functions returns the state after performing jump calculation to a rand module internal state, which is equivalent to perform a large number of calls of calculating new states for XorShift*/+ algorithms. This commit add jump functions for exsplus and exs1024 algorithms, and a wrapper function jump/1. The wrapper function will cause error with reason "not_implemented" if the jump function for the algorithm is not implemented. This commit adds following new functionalities: - Add new functions rand:jump/0 and rand:jump/1 - Add the member jump to type alg_handler(), a fun for performing the jump function - Add jump functions for exsplus, equivalent to 2^64 calls - Add jump functions for exs1024, equivalent to 2^512 calls - Revise seed_put/1, seed/1, seed/2 See <https://github.com/erlang/otp/pull/1235#discussion_r86950557> - Add dummy jump function for exs64 calling erlang:error(not_implemented) - Add jump function test cases as follows: * Add Common Test group reference_jump * Add tests for jump/0 to reference_jump_procdict/1 * Rename tests for jump/1 to reference_jump_state/1 * Rename gen_jump/1 to gen_jump_1/1 * Add Common Tests reference_jump_procdict and reference_jump_state to the group reference_jump - Add jump function documentation This commit also changes the Copyright year for Kenji Rikitake's code from 2015 to 2015-2016.

ECC certs should preferably use SHA2, this is what we want to be testing. Also assembling of all available test suites must consider TLS version.

The default value of 'mod' is '[]' and 'start_phases' is 'undefined' in .app, but this value was not accepted if given in the .app file. This is now corrected.

The constant ?WORD_WIDTH is renamed ?BITS_IN_WORD, and a new constant ?BITS_IN_BYTE is introduced. Additionally, a bug in a currently unused case clause of llvm_type_from_size/1 is fixed (the size of a word was hardcoded to 64 bits).

This reverts commit 52fae83743a6e84d719f4f82fe45e6e0efdbd6f0: Check libsctp for sctp funcs in configure.in Call AC_CHECK_LIB before calling AC_CHECK_FUNCS to check for functions in libsctp. Otherwise AC_CHECK_FUNCS will not link with libsctp to see if function exists. Reverting to the old behaviour of not checking for libsctp before checking for sctp functions. Then it works on Linux by loading libsctp and looking up the symbols i runtime, and it works on FreeBSD since there is no separate libsctp to link against - the functions are part of the default system libraries.

2016-11-07hipe_llvm: Work around LLVM 3.9 sdesc bugMagnus Lång
As of LLVM 3.9, the x86-call-frame-opt pass in LLVM's X86 backend causes the stack descriptors to contain incorrect (or even negative) frame sizes or root slot offsets. This might cause LLVM-compiled modules to be rejected during loading with a badarg exception in hipe_bifs:enter_sdecs/1 (which additionally prints a "hipe_bifs_enter_sdesc_1: bad sdesc!" message to stderr), or it might cause corruption or segmentation faults when walking stacks (f.ex. during GC) containing frames compiled with ErLLVM. As a workaround, we pass the -no-x86-call-frame-opt flag to llc when the version is at least 3.9
2016-11-07hipe_llvm: Fix incorrect atom alignment assumptionMagnus Lång
ErLLVM was declaring atoms in the following manner: @atom_ok = external constant i64 ; Used inside a function like this %var = ptrtoint i64* @atom_ok to i64 However, doing so makes LLVM think the `atom_ok` is 8-byte aligned, since it refers to a i64 value. This resulted in LLVM occasionally incorrectly optimising away type tests on atoms, causing incorrect behaviour or even segfaults. One such case is in bs_match_compiler:coverage_apply/2, in which an is_boxed test on a literal atom was optimised away, causing the code to try and load the "header" of an atom. This problem reproduces with LLVM versions 3.7 through 3.9. By declaring atoms as i8 (byte) constants instead, LLVM no longer makes these alignment assumptions, and the bug is fixed.
