Willy Tarreau	71de04134e	IMPORT: slz: define and use a __fallthrough statement for switch/case ... When the code is preprocessed first and compiled later, such as when built under distcc, the "fall through" comments are dropped and warnings are emitted. Let's use the alternative "fallthrough" attribute instead, that is supported by versions of gcc and clang that also produce this warning. This is libslz upstream commit 0fdf8ae218f3ecb0b7f22afd1a6b35a4f94053e2	2022-11-14 11:14:02 +01:00
Willy Tarreau	9e274280a4	IMPORT: slz: do not produce the crc32_fast table when CRC is natively supported ... On ARM with native CRC support, no need to inflate the executable with a 4kB CRC table, let's just drop it. This is slz upstream commit d8715db20b2968d1f3012a734021c0978758f911.	2021-05-12 09:29:33 +02:00
Willy Tarreau	ab2b7828e2	IMPORT: slz: import slz into the tree ... SLZ is rarely packaged by distros and there have been complaints about the CPU and memory usage of ZLIB, leading to some suggestions to better address the issue by simply integrating SLZ into the tree (just 3 files). See discussions below: https://www.mail-archive.com/haproxy@formilux.org/msg38037.html https://www.mail-archive.com/haproxy@formilux.org/msg40079.html https://www.mail-archive.com/haproxy@formilux.org/msg40365.html This patch does just this, after minor adjustments to these files: - tables.h was renamed to slz-tables.h - tables.h had the precomputed tables removed since not used here - slz.c uses includes <import/slz*> instead of "slz*.h" The slz commit imported here was b06c172 ("slz: avoid a build warning with -Wimplicit-fallthrough"). No other change was performed either to SLZ nor to haproxy at this point so that this operation may be replicated if needed for a future version.	2021-04-22 15:50:41 +02:00
