* u_dynarray: turn util_dynarray_{grow, resize} into element-oriented macrosNicolai Hähnle2019-06-121-14/+32
| | | | | | | | | | | | | | | | | | | | | | | | The main motivation for this change is API ergonomics: most operations on dynarrays are really on elements, not on bytes, so it's weird to have grow and resize as the odd operations out. The secondary motivation is memory safety. Users of the old byte-oriented functions would often multiply a number of elements with the element size, which could overflow, and checking for overflow is tedious. With this change, we only need to implement the overflow checks once. The checks are cheap: since eltsize is a compile-time constant and the functions should be inlined, they only add a single comparison and an unlikely branch. v2: - ensure operations are no-op when allocation fails - in util_dynarray_clone, call resize_bytes with a compile-time constant element size v3: - fix iris, lima, panfrost Reviewed-by: Marek Olšák <[email protected]>
* u_dynarray: return 0 on realloc failure and ensure no-opNicolai Hähnle2019-06-121-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | We're not very good at handling out-of-memory conditions in general, but this change at least gives the caller the option of handling it gracefully and without memory leaks. This happens to fix an error in out-of-memory handling in i965, which has the following code in brw_bufmgr.c: node = util_dynarray_grow(vma_list, sizeof(struct vma_bucket_node)); if (unlikely(!node)) return 0ull; Previously, allocation failure for util_dynarray_grow wouldn't actually return NULL when the dynarray was previously non-empty. v2: - make util_dynarray_ensure_cap a no-op on failure, add MUST_CHECK attribute - simplify the new capacity calculation: aside from avoiding a useless loop when newcap is very large, this also avoids an infinite loop when newcap is larger than 1 << 31 Reviewed-by: Marek Olšák <[email protected]>

| | | | | | | | | | | | | | | | | | | | A significant portion of the time spent in nir_opt_cse for the Dolphin ubershaders was in resizing the set. When resizing a hash table, we know in advance that each new element to be inserted will be different from every other element, so we don't have to compare them, and there will be no tombstone elements, so we don't have to worry about caching the first-seen tombstone. We add a specialized add function which skips these steps entirely, speeding up resizing.

| | | | | | | | | | | | | | | | | | | | | | Unfortunately GCC can't do this for us, probably because we call the key comparison function which GCC can't prove won't modify arbitrary memory. This is a pretty hot function, so do the optimization manually to be sure the compiler will get it right. While we're here, make the computation of the new probe address use a single conditional subtract instead of a modulo, since we know that it won't ever get as big as 2 * ht->size before the modulo.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The most expensive part of register allocation is the ra_simplify step which is a fixed-point algorithm with a worst-case complexity of O(n^2) which adds the registers to a stack which we then use later to do the actual allocation. This commit uses bit sets and changes the core loop of ra_simplify to first walk 32-node chunks and then walk each chunk. This lets us skip whole 32-node chunks in one go based on bit operations and compute the minimum q value potentially 32x as fast. Of course, the algorithm still has the same fundamental O(n^2) run-time but the constant is now much lower. In the nasty Aztec Ruins compute shader, this shaves a full four seconds off the 30s compile time for a release build of mesa. In a debug build (needed for accurate stack traces), perf says that ra_select takes 20% of runtime before this patch and only 5-6% of runtime after this patch. It also makes shader-db runs faster.
