The memory must be freed with DEALLOCATE_LOCAL before the - * function that made the allocation returns. You should not ask for - * large blocks of memory with this function, since on many platforms - * the memory comes from the stack, which may have limited size. - * - * void DEALLOCATE_LOCAL(void *) - * Frees the memory allocated by ALLOCATE_LOCAL. Omission of this - * step may be harmless on some platforms, but will result in - * memory leaks or worse on others. - * - * Before including this file, you should define two macros, - * ALLOCATE_LOCAL_FALLBACK and DEALLOCATE_LOCAL_FALLBACK, that have the - * same characteristics as ALLOCATE_LOCAL and DEALLOCATE_LOCAL. The - * header uses the fallbacks if it doesn't know a "better" way to define - * ALLOCATE_LOCAL and DEALLOCATE_LOCAL. Typical usage would be: - * - * #define ALLOCATE_LOCAL_FALLBACK(_size) malloc(_size) - * #define DEALLOCATE_LOCAL_FALLBACK(_ptr) free(_ptr) - * #include "Xalloca.h" - */ - -#ifndef XALLOCA_H -#define XALLOCA_H 1 - -#ifndef INCLUDE_ALLOCA_H -# if defined(__SUNPRO_C) /* Need to add more here to match Imake *.cf's */ -# define INCLUDE_ALLOCA_H -# endif -#endif - -#ifdef INCLUDE_ALLOCA_H -# include <alloca.h> -#endif - -#ifndef NO_ALLOCA -/* - * os-dependent definition of local allocation and deallocation - * If you want something other than (DE)ALLOCATE_LOCAL_FALLBACK - * for ALLOCATE/DEALLOCATE_LOCAL then you add that in here. - */ -# if defined(__HIGHC__) -# ifndef NCR - extern char *alloca(); -# if HCVERSION < 21003 -# define ALLOCATE_LOCAL(size) alloca((int)(size)) - pragma on(alloca); -# else /* HCVERSION >= 21003 */ -# define ALLOCATE_LOCAL(size) _Alloca((int)(size)) -# endif /* HCVERSION < 21003 */ -# else /* NCR */ -# define ALLOCATE_LOCAL(size) alloca(size) -# endif -# endif /* defined(__HIGHC__) */ - - -# ifdef __GNUC__ -# ifndef alloca -# define alloca __builtin_alloca -# endif /* !alloca */ -# define ALLOCATE_LOCAL(size) alloca((int)(size)) -# else /* ! __GNUC__ */ - -/* - * warning: old mips alloca (pre 2.10) is unusable, new one is built in - * Test is easy, the new one is named __builtin_alloca and comes - * from alloca.h which #defines alloca. - */ -# ifndef NCR -# if defined(vax) || defined(sun) || defined(apollo) || defined(stellar) || defined(alloca) -/* - * Some System V boxes extract alloca.o from /lib/libPW.a; if you - * decide that you don't want to use alloca, you might want to fix it here. - */ -/* alloca might be a macro taking one arg (hi, Sun!), so give it one. */ -# define __Xnullarg /* as nothing */ -# ifndef X_NOT_STDC_ENV - extern void *alloca(__Xnullarg); -# else - extern char *alloca(__Xnullarg); -# endif -# define ALLOCATE_LOCAL(size) alloca((int)(size)) -# endif /* who does alloca */ -# endif /* NCR */ -# endif /* __GNUC__ */ - -#endif /* NO_ALLOCA */ - -#if !defined(ALLOCATE_LOCAL) -# if defined(ALLOCATE_LOCAL_FALLBACK) && defined(DEALLOCATE_LOCAL_FALLBACK) -# define ALLOCATE_LOCAL(_size) ALLOCATE_LOCAL_FALLBACK(_size) -# define DEALLOCATE_LOCAL(_ptr) DEALLOCATE_LOCAL_FALLBACK(_ptr) -# else /* no fallbacks supplied; error */ -# define ALLOCATE_LOCAL(_size) ALLOCATE_LOCAL_FALLBACK undefined! -# define DEALLOCATE_LOCAL(_ptr) DEALLOCATE_LOCAL_FALLBACK undefined! -# endif /* defined(ALLOCATE_LOCAL_FALLBACK && DEALLOCATE_LOCAL_FALLBACK) */ -#else -# if !defined(DEALLOCATE_LOCAL) -# define DEALLOCATE_LOCAL(_ptr) do {} while(0) -# endif -#endif /* defined(ALLOCATE_LOCAL) */ - -#endif /* XALLOCA_H */ |
