782bfb858a fixed very minor inefficiency (nbSeq==127) 
The nbSeq "short" format (1-byte)
is compatible with any value < 128.

However, the code would cautiously only accept values < 127.
This is not an error, because the general 2-bytes format
is compatible with small values < 128.
Hence the inefficiency never triggered any warning.

Spotted by Intel's Smita Kumar.

ff6c81d90c Fix the build on GCC 4.x after 812e8f2a1 
The ancient GCC 4.x doesn't understand the "optimize" attribute until 4.4.
Fix the build on platforms with GCC 4.x < 4.4 by limiting the DONT_VECTORIZE
definition to GCC 5 and greater.

Noticed and patch proposed by Warner Losh <imp@FreeBSD.org>.

to produce same content on both 32 and 64-bit platforms
by removing floating from literal table determination.

also : added checksum trace in compression control test,
so that it's easier to determine if test fails
as a consequence of compressing a different sample.

[legacy] Fix bug in zstd-0.5 decoder
 2019-07-22 18:06:18 -04:00

e6edcfa795 [legacy] Fix bug in zstd-0.5 decoder 
The match length and literal length extra bytes could either
by 2 bytes or 3 bytes in version 0.5. All earlier verions were
always 3 bytes, and later version didn't have dumps.

The bug, introduced by commit 0fd322f812211e653a83492c0c114b933f8b6bc5,
was triggered when the last dump was a 2-byte dump, because we didn't
separate that case from a 3-byte dump, and thought we were over-reading.

I've tested this fix with every zstd version < 1.0.0 on the buggy file,
and we are now always successfully decompressing with the right
checksum.

Fixes #1693.
