f31715f5e0 Enable use of bswap intrinsics in clang
Necessary because clang disguises itself as an older (__GNUC_MINOR__ = 2) GCC.

Improved decompression speed
2018-10-10 19:16:35 -07:00

6ed3b526e4 restored bitMask for shift values
since corrupted bitstreams can generate too large values.

This slightly reduces the benefits from clang on my laptop.
gcc results and code generation are not affected.

433059bbb2 fixed minor gcc warning
gcc-8 on Linux doesn't like usage of strncat :
`warning: ‘strncat’ output truncated before terminating nul copying as many bytes from a string as its length`.

Not sure what was wrong, it might be a false positive,
but the logic is simple enough to replaced by a simple `memcpy()`,
thus avoiding the shenanigans of null-terminated strings.

d3ec23313d improved decompression speed
while reviewing #1364,
I found a decompression speed improvement.

On my laptop, the new code decompresses +5-6% faster on clang
and +2-3% faster on gcc.

not bad for an accidental optimization...

`ZSTD_btlazy2`: Avoid Erroneously Trampling on Match with Worse Dictionary Match

f17c1df1ac backtrace support compiled with more conditions
following #1356,
only enable backtrace compilation on linux+glibc.

Also, disable backtrace by default from "release" compilation,
so that less platforms get impacted by the new requirements.
Can be manually enabled/disabled using BACKTRACE=1/0.

execinfo.h

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

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.

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.

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.
