Conrad Meyer 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>.

[legacy] Fix bug in zstd-0.5 decoder
 2019-07-22 18:06:18 -04:00
Nick Terrell 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 0fd322f812,
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.
