The asm code shows multiple conversions. Gcc has always been terribly bad at dealing with chars, which are constantly converted to ints for every operation and zero-extended after each operation. But here in addition there are conversions before and after the flsnz(). Let's just mark the variables as long and use flsnz_long() to process them without any conversion. This shortens the code and makes it slightly faster. Note that the fls operations could make use of __builtin_clz() on gcc 4.6 and above, and it would be useful to implement native support for ARM as well. This is cbtree commit 1f0f83ba26f2279c8bba0080a2e09a803dddde47. This is ebtree commit 9c38dcae22a84f0b0d9c5a56facce1ca2ad0aaef.
The HAProxy documentation has been split into a number of different files for ease of use. Please refer to the following files depending on what you're looking for : - INSTALL for instructions on how to build and install HAProxy - BRANCHES to understand the project's life cycle and what version to use - LICENSE for the project's license - CONTRIBUTING for the process to follow to submit contributions The more detailed documentation is located into the doc/ directory : - doc/intro.txt for a quick introduction on HAProxy - doc/configuration.txt for the configuration's reference manual - doc/lua.txt for the Lua's reference manual - doc/SPOE.txt for how to use the SPOE engine - doc/network-namespaces.txt for how to use network namespaces under Linux - doc/management.txt for the management guide - doc/regression-testing.txt for how to use the regression testing suite - doc/peers.txt for the peers protocol reference - doc/coding-style.txt for how to adopt HAProxy's coding style - doc/internals for developer-specific documentation (not all up to date)
