Initialize tunable list with the GLIBC_TUNABLES environment variable
Read tunables values from the users using the GLIBC_TUNABLES environment variable. The value of this variable is a colon-separated list of name=value pairs. So a typical string would look like this: GLIBC_TUNABLES=glibc.malloc.mmap_threshold=2048:glibc.malloc.trim_threshold=1024 * config.make.in (have-loop-to-function): Define. * elf/Makefile (CFLAGS-dl-tunables.c): Add -fno-tree-loop-distribute-patterns. * elf/dl-tunables.c: Include libc-internals.h. (GLIBC_TUNABLES): New macro. (tunables_strdup): New function. (parse_tunables): New function. (min_strlen): New function. (__tunables_init): Use the new functions and macro. (disable_tunable): Disable tunable from GLIBC_TUNABLES. * malloc/tst-malloc-usable-tunables.c: New test case. * malloc/tst-malloc-usable-static-tunables.c: New test case. * malloc/Makefile (tests, tests-static): Add tests.
