Subject: [PATCH v9 2/6] eal: extend bit manipulation functionality
Date: Wed, 18 Sep 2024 11:04:41 +0200	[thread overview]
Message-ID: <20240918090445.725283-3-mattias.ronnblom@ericsson.com> (raw)
In-Reply-To: <20240918090445.725283-1-mattias.ronnblom@ericsson.com>

Add functionality to test and modify the value of individual bits in
32-bit or 64-bit words.

These functions have no implications on memory ordering, atomicity and
does not use volatile and thus does not prevent any compiler
optimizations.

PATCH v3:
 * Remove unnecessary <rte_compat.h> include.
 * Remove redundant 'fun' parameter from the __RTE_GEN_BIT_*() macros
   (Jack Bond-Preston).
 * Introduce __RTE_BIT_BIT_OPS() macro, consistent with how things
   are done when generating the atomic bit operations.
 * Refer to volatile bit op functions as variants instead of families
   (macro parameter naming).

RFC v6:
 * Have rte_bit_test() accept const-marked bitsets.

RFC v4:
 * Add rte_bit_flip() which, believe it or not, flips the value of a bit.
 * Mark macro-generated private functions as experimental.
 * Use macros to generate *assign*() functions.

RFC v3:
 * Work around lack of C++ support for _Generic (Tyler Retzlaff).
 * Fix ','-related checkpatch warnings.
