2001-08-11 Ulrich Drepper <drepper@redhat.com> * malloc/malloc.c (ptmalloc_init): Don't call getenv five times. Instead use new function next_env_entry which iterates over the environment once. * sysdeps/arm/dl-machine.h (elf_machine_runtime_setup): Only set _dl_profile_map for the right object. * elf/dl-reloc.c (_dl_relocate_object): Allocate l_reloc_result only if consider_profiling is != 0, not if _dl_profile != NULL. * sysdeps/generic/dl-environ.c (_dl_next_ld_env_entry): Optimize a bit. Now returns pointer to first character set "LD_". * elf/rtld.c (process_envvars): Adjust for change above. * sysdeps/unix/sysv/linux/dl-librecon.h (EXTRA_LD_ENVVARS): Likewise. * sysdeps/unix/sysv/linux/i386/dl-librecon.h (EXTRA_LD_ENVVARS): Likewise. 2001-08-10 Wolfram Gloger <wg@malloc.de> * malloc/malloc.c (grow_heap): Use mmap() rather than mprotect() to allocate new memory, for better performance with Linux-2.4.x.
