don't assume __linux__ means __GLIBC__ on BACKTRACES_ENABLE

don't assume __linux__ means __GLIBC__ on BACKTRACES_ENABLE 
check for __GLIBC__ instead of __linux__ as musl libc doesn't provide
execinfo.h

fixes compilation on Alpine Linux and Void Linux musl arches.

Yann Collet efbc3e823d fixed paramgrill wrong assert() conditions 
and slightly refactored affected function.

Honestly, the formula calculating variance should get a second reviewing round,
it's not clear if it's correct.

Yann Collet 549c19b42e portability macro flags updates, for Haiku 
some non-trivial changes to platform.h and util.h,
initially related to compilation for Haiku,
but I used this opportunity to make them cleaner
and add some documentation.

Noticed several tests that could be improved
(too harsh conditions, useless exception, etc.)
but I did not dare modifying too many tests just before release.

Fix #1082
 2018-10-02 16:37:58 -07:00
Yann Collet 3ca6261223 fixed static analyzer warnings 
note : for some reason,
scan-build version on my laptop found problems within fastcover.c
that scan-build on travisCI does not flag.

They are, as usual, false positive :
the analyzer does not understand that a table (`offset`) is correctly filled before usage.

Yann Collet d98733b37e restored backtrace on failure 
for Linux and Mac OS-X.

Note : the backtraces fires up through a trap
before the sanitizer get a chance to report.
There are situations where the sanitizer report is actually preferable.

It might be good to consider a kind of build macro
which can disable backtrace
when sanitizer is enabled.

W. Felix Handte 5b296869df Revert Ability to Set HashLog and ChainLog on Context When Dict is Attached 
This capability is not needed / used in the current unit of work. I'll
re-introduce it later, when we start allowing users to override the deduced
working context logs.

W. Felix Handte bad74c4781 Use Working Ctx Logs when not in DMS Mode 
We pre-hash the ptr for the dict match state sometimes. When that actually
happens, a hashlog of 0 can produce undefined behavior (right shift a long
long by 64). Only applies to unoptimized compilations, since when
optimizations are applied, those hash operations are dropped when we're not
actually in dms mode.
