From 299571aca34d36e637e43cfbba6275662d0d7795 Mon Sep 17 00:00:00 2001 From: Damjan Marion Date: Sat, 19 Mar 2022 00:07:52 +0100 Subject: vppinfra: vector allocator rework - support of in-place growth of vectors (if there is available space next to existing alloc) - drops the need for alloc_aligned_at_offset from memory allocator, which allows easier swap to different memory allocator and reduces malloc overhead - rework of pool and vec macros to inline functions to improve debuggability - fix alignment - in many cases macros were not using native alignment of the particular datatype. Explicitly setting alignment with XXX_aligned() versions of the macro is not needed anymore in > 99% of cases - fix ASAN usage - avoid use of vector of voids, this was root cause of several bugs found in vec_* and pool_* function where sizeof() was used on voids instead of real vector data type - introduce minimal alignment which is currently 8 bytes, vectors will be always aligned at least to that value (underlay allocator actually always provide 16-byte aligned allocs) Type: improvement Change-Id: I20f4b081bb13bbf7bc0ace85cc4e301787f12fdf Signed-off-by: Damjan Marion --- src/vppinfra/sparse_vec.h | 8 +++----- 1 file changed, 3 insertions(+), 5 deletions(-) (limited to 'src/vppinfra/sparse_vec.h') diff --git a/src/vppinfra/sparse_vec.h b/src/vppinfra/sparse_vec.h index 4bc2cbdeaea..6cab868a8b2 100644 --- a/src/vppinfra/sparse_vec.h +++ b/src/vppinfra/sparse_vec.h @@ -76,11 +76,9 @@ sparse_vec_new (uword elt_bytes, uword sparse_index_bits) ASSERT (sparse_index_bits <= 16); - v = _vec_resize ((void *) 0, - /* length increment */ 8, - /* data bytes */ 8 * elt_bytes, - /* header bytes */ sizeof (h[0]), - /* data align */ 0); + v = _vec_realloc (0, /* data bytes */ 8, elt_bytes, + /* header bytes */ sizeof (h[0]), /* data align */ 0, + /* heap */ 0); /* Make space for invalid entry (entry 0). */ _vec_len (v) = 1; -- cgit 1.2.3-korg
