Subject: [dpdk-dev] [PATCH v2 00/10] Add an option to use LTO for DPDK build
Date: Tue, 17 Sep 2019 09:57:44 +0200 [thread overview]
Message-ID: <20190917075754.8310-1-amo@semihalf.com> (raw)
This patch series adds an option to make use of link time optimization
(if compiler has support for it). It is split as follows:
- 1st patch (build) is the enablement
- remaining patches are fixes for the warnings produced by the compiler
and they are split by directory/subsystem so their maintainers can
easily find and verify the changes - please note that there are two
groups:
* errors (or possible errors) - with title "fix possible use ..."
* false positives - warnings that _I_ think are not valid and the
changes are made only to silence the compiler.
v2 Changes:
-----------
- fixed building of shared libraries:
- gcc does not scan top level assembler statements so it missed that
function implementations for specific versions were being used and
was removing them
- fixed meson.build config files:
- moved from 'enable_lto' project option to built-in 'b_lto'
- documented that 'default_library' should be 'shared':
with 'default_library=static' (the default) the meson build with LTO
is broken - this is because, SHARED_LIB is fixed in rte_config.h
used by meson which leads to no alias for default version in
generated static libraries (MAP_STATIC_SYMBOL() is empty)
- app/test: added log for failed bonding "config get"
Andrzej Ostruszka (10):
