strusPattern works on Intel 64-bit CPUs and 32-bit CPUs with SSSE3 only (not SPARC, not ARM)

[andreasbaumann]

Several reasons:

• old machines without SSSE3 fail
• non-Intel architectures like ARM and SPARC are not supported
• Travis builds fail because there are too many errors and Travis aborts the build:

...
/home/travis/build/andreasbaumann/strusStream/3rdParty/hyperscan/src/nfa/limex_runtime.h:103:46: note: in expansion of macro ‘NFA_EXEC_LIM_SHIFT’
             succ = JOIN(or_, gls_type)(succ, NFA_EXEC_LIM_SHIFT(gls_type, 1)); \
                                              ^

The log length has exceeded the limit of 4 MB (this usually means that the test suite is raising the same exception over and over).

The job has been terminated

• FreeBSD/OSX: clang issue around some missing builtin-functions:

                __v4si cmp0 = __builtin_ia32_pcmpeqd128( event4, eventblkar[ ii + 0]);
                              ^~~~~~~~~~~~~~~~~~~~~~~~~

Stop.

__builtin_ia32_pcmpeqd128
in ruleMatcherAutomaton.cpp can be replaced.

Meanwhile Workaround: #define STRUS_USE_SSE_SCAN_TRIGGERS in ruleMatcherAutomaton.cpp disable for FreeBSD/OSX.

[andreasbaumann]

The Travis build issue can be solved by using more relaxed compilation flags for hyperscan.

Now stuck in:

[patrickfrey]

This one fixed also.

[andreasbaumann]

Travis Ubuntu g++ builds now. After fixing the compilation flags to the genuine hyperscan compilation flags we get almost no warnings anymore. clang and MacOS Travis builds still fail due to too many warnings in Boost.

[andreasbaumann]

There is a problem with clang though:
