From 6c18e508f10aa5bf42dc80691654b9cde2a661cd Mon Sep 17 00:00:00 2001 From: Björn Steinbrink Date: Fri, 24 Oct 2014 11:08:42 +0200 Subject: Make MIN_ALIGN a const to allow better optimization With MIN_ALIGN as a static, other crates don't have access to its value at compile time, because it is an extern global. That means that the checks against it can't be optimized out, which is rather unfortunate. So let's make it a constant instead. --- src/liballoc/heap.rs | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/liballoc') diff --git a/src/liballoc/heap.rs b/src/liballoc/heap.rs index 5a0f860ff84..0e5aca18ec7 100644 --- a/src/liballoc/heap.rs +++ b/src/liballoc/heap.rs @@ -112,10 +112,10 @@ unsafe fn exchange_free(ptr: *mut u8, size: uint, align: uint) { #[cfg(any(target_arch = "arm", target_arch = "mips", target_arch = "mipsel"))] -static MIN_ALIGN: uint = 8; +const MIN_ALIGN: uint = 8; #[cfg(any(target_arch = "x86", target_arch = "x86_64"))] -static MIN_ALIGN: uint = 16; +const MIN_ALIGN: uint = 16; #[cfg(jemalloc)] mod imp { -- cgit 1.4.1-3-g733a5
