435cd23823 Literal API: update dev-reference 2019-08-13 14:52:03 +08:00
Hong, Yang A
23e5f06594 add new Literal API for pure literal expressions: 
Design compile time api hs_compile_lit() and hs_compile_lit_multi()
to handle pure literal pattern sets. Corresponding option --literal-on
is added for hyperscan testing suites. Extended parameters and part of
flags are not supported for this api.

7ea4e06275 tools: hscollider FTBS in alpine linux 
alpine uses musl instead of glibc and therefore doesn't have backtrace()
as part of its libc.

POSIX mandates that _exit() be defined through unistd.h which used to be
included together with execinfo.h when backtrace() was detected and
therefore it happened to build fine for linux or freebsd (when using
libexecinfo from the system or ports).

since there was a macro already defined to test for unistd.h use that
instead and decouple this dependency, so that the code could be built
even when no backtrace() is provided (as expected also in OpenBSD)

5a1b02bc10 Fix uninitialized use of scatter_unit_uX due to padding 
These non-packed structures are placed into a std::vector.  Later, they
contents of the vector are memcpy'd and the CRC of this space is taken.
Some compilers will zero the struct padding but GCC8.2 with -O2 at least
will not.  This means that the CRC is based on uninitialized memory.

Since it is expected that these bytes will be memcpy'd, zero in place once
they're in the std::vector.

Found by Valgrind.

e15954a4bd Avoid array-bounds error when debug/fortify enabled 
This code causes GCC to error out due to a bounds error with the following set

	-D_GLIBCXX_DEBUG
	-D_FORTIFY_SOURCE=2

The solution is to copy via iterator.
