From 796e6ee3062dc7d2eae5cb9a48f66a4e84b2992a Mon Sep 17 00:00:00 2001 From: Alexander Larsson Date: Tue, 29 Sep 2020 16:03:06 +0200 Subject: [PATCH] snapshot: Preallocate and don't memset the state stack Most of the time the snapshot is less than 16 levels deep (did some testing in gtk-demo), so lets pre-allocate 16 levels of state stack to avoid the extra allocation most of the time. --- gtk/gtksnapshot.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/gtk/gtksnapshot.c b/gtk/gtksnapshot.c index ab19aa8ac1..bca48076cd 100644 --- a/gtk/gtksnapshot.c +++ b/gtk/gtksnapshot.c @@ -132,6 +132,8 @@ static void gtk_snapshot_state_clear (GtkSnapshotState *state); #define GDK_ARRAY_ELEMENT_TYPE GtkSnapshotState #define GDK_ARRAY_FREE_FUNC gtk_snapshot_state_clear #define GDK_ARRAY_BY_VALUE 1 +#define GDK_ARRAY_PREALLOC 16 +#define GDK_ARRAY_NO_MEMSET 1 #include "gdk/gdkarrayimpl.c" /* This is a nasty little hack.
