From ad0aa1f54975bd20e30559930ea48a3568441ff4 Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Fri, 7 Jun 2024 13:42:43 +0200 Subject: elf: Remove LD_HWCAP_MASK / tunable glibc.cpu.hwcap_mask Remove the environment variable LD_HWCAP_MASK and the tunable glibc.cpu.hwcap_mask as those are not used anymore in common-code after removal in elf/dl-cache.c:search_cache(). The only remaining user is sparc32 where it is used in elf_machine_matches_host(). If sparc32 does not need it anymore, we can get rid of it at all. Otherwise we could also move LD_HWCAP_MASK / tunable glibc.cpu.hwcap_mask to be sparc32 specific.
