Subject: ZSTD_createCCtx_advanced() now uses ZSTD_calloc()
X-Git-Tag: v1.3.0~1^2~17^2~71
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c4f46b94ce6ba497c75b0b44d9e45a0d2872602d;p=thirdparty%2Fzstd.git

ZSTD_createCCtx_advanced() now uses ZSTD_calloc()

initially uses calloc() instead of memset().

Performance improvement is unlikely measurable,
since ZSTD_CCtx is now very small,
with all tables transferred into workSpace.
