From e404fb16fc35210219159a446f7c993760a37316 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 22 Aug 2006 06:19:12 +0000 Subject: * malloc/malloc.c (DEFAULT_MMAP_THRESHOLD_MAX): For 32-bit platforms define as 1MB. For 64-bit platforms as 32MB. The lower limit is needed to avoid the exploding of the address space requirement for secondary heaps. * malloc/arena.c (HEAP_MAX_SIZE): Define using DEFAULT_MMAP_THRESHOLD_MAX if it is defined. --- malloc/arena.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'malloc/arena.c') diff --git a/malloc/arena.c b/malloc/arena.c index 6f0a9df..e96b3b4 100644 --- a/malloc/arena.c +++ b/malloc/arena.c @@ -24,7 +24,11 @@ #define HEAP_MIN_SIZE (32*1024) #ifndef HEAP_MAX_SIZE -#define HEAP_MAX_SIZE (1024*1024) /* must be a power of two */ +# ifdef DEFAULT_MMAP_THRESHOLD_MAX +# define HEAP_MAX_SIZE DEFAULT_MMAP_THRESHOLD_MAX +# else +# define HEAP_MAX_SIZE (1024*1024) /* must be a power of two */ +# endif #endif /* HEAP_MIN_SIZE and HEAP_MAX_SIZE limit the size of mmap()ed heaps -- cgit v1.1
