/* * Macros to transparently switch between the stack and heap for large * allocations. The former is useful on MMU systems as it results in * smaller code, but the latter is required on NoMMU systems. This is * due to small stacks that cannot grow and so doing large allocs will * cause a stack overflow. * * Copyright (C) 2010 Mike Frysinger <vapier@gentoo.org> * Licensed under the LGPL v2.1, see the file COPYING.LIB in this tarball. */ #ifndef _UCLIBC_ALLOC_H #define _UCLIBC_ALLOC_H #include <alloca.h> #include <stdlib.h> #ifdef __ARCH_USE_MMU__ # define stack_heap_alloc(x) alloca(x) # define stack_heap_free(x) do { if (0) free(x); } while (0) #else # define stack_heap_alloc(x) malloc(x) # define stack_heap_free(x) free(x) #endif #endif |
