There is only a single\nlocation accepted by both toolchains.\n\nFor variables standard C11 offers alignas(a) supported by conformant\ncompilers i.e. both MSVC and GCC.\n\nFor types the standard offers no alignment facility that compatibly\ninteroperates with C and C++ but may be achieved by relocating the\nplacement of __rte_aligned(a) to the aforementioned location accepted\nby all currently supported toolchains.\n\nTo allow alignment for both compilers do the following:\n\n* Move __rte_aligned from the end of {struct,union} definitions to\n be between {struct,union} and tag.\n\n The placement between {struct,union} and the tag allows the desired\n alignment to be imparted on the type regardless of the toolchain being\n used for all of GCC, LLVM, MSVC compilers building both C and C++.\n\n* Replace use of __rte_aligned(a) on variables/fields with alignas(a).\n\nSigned-off-by: Tyler Retzlaff <roretzla@linux.microsoft.com>\nAcked-by: Morten Brørup <mb@smartsharesystems.com>\n---\n lib/jobstats/rte_jobstats.h | 8 ++++----\n 1 file changed, 4 insertions(+), 4 deletions(-)", "diff": "diff --git a/lib/jobstats/rte_jobstats.h b/lib/jobstats/rte_jobstats.h\nindex 45b460e..bdd85fe 100644\n--- a/lib/jobstats/rte_jobstats.h\n+++ b/lib/jobstats/rte_jobstats.h\n@@ -32,7 +32,7 @@\n typedef void (*rte_job_update_period_cb_t)(struct rte_jobstats *job,\n \t\tint64_t job_result);\n \n-struct rte_jobstats {\n+struct __rte_cache_aligned rte_jobstats {\n \tuint64_t period;\n \t/**< Estimated period of execution. */\n \n@@ -65,9 +65,9 @@ struct rte_jobstats {\n \n \tstruct rte_jobstats_context *context;\n \t/**< Job stats context object that is executing this job. */\n-} __rte_cache_aligned;\n+};\n \n-struct rte_jobstats_context {\n+struct __rte_cache_aligned rte_jobstats_context {\n \t/** Variable holding time at different points:\n \t * -# loop start time if loop was started but no job executed yet.\n \t * -# job start time if job is currently executing.\n@@ -111,7 +111,7 @@ struct rte_jobstats_context {\n \n \tuint64_t loop_cnt;\n \t/**< Total count of executed loops with at least one executed job. */\n-} __rte_cache_aligned;\n+};\n \n /**\n * Initialize given context object with default values.\n", "prefixes": [ "v6", "31/39" ] }
