From 3f5c647de97a424d8a06e85b912ed46cc3ca8298 Mon Sep 17 00:00:00 2001 From: bfredl Date: Thu, 2 Jun 2022 09:18:13 +0200 Subject: perf(memory): use an arena for RPC decoding drawback: tracing memory errors with ASAN is less accurate for arena allocated memory. Therefore, to start with it is being used for Object types around serialization/deserialization exclusively. This is going to have a large impact especially when TUI is refactored as a co-prosess as all UI events will be serialized and deserialized by nvim itself. --- src/nvim/memory.h | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'src/nvim/memory.h') diff --git a/src/nvim/memory.h b/src/nvim/memory.h index a4be2643d8..0c048e1b5b 100644 --- a/src/nvim/memory.h +++ b/src/nvim/memory.h @@ -37,6 +37,20 @@ extern MemRealloc mem_realloc; extern bool entered_free_all_mem; #endif +typedef struct consumed_blk { + struct consumed_blk *prev; +} *ArenaMem; + +#define ARENA_ALIGN sizeof(void *) + +typedef struct { + char *cur_blk; + size_t pos, size; +} Arena; + +// inits an empty arena. use arena_start() to actually allocate space! +#define ARENA_EMPTY { .cur_blk = NULL, .pos = 0, .size = 0 } + #ifdef INCLUDE_GENERATED_DECLARATIONS # include "memory.h.generated.h" #endif -- cgit
