Florian Weimer	73fc4e28b9	Linux: Consolidate auxiliary vector parsing (redo) ... And optimize it slightly. This is commit 8c8510ab27 revised. In _dl_aux_init in elf/dl-support.c, use an explicit loop and -fno-tree-loop-distribute-patterns to avoid memset. Reviewed-by: Szabolcs Nagy <szabolcs.nagy@arm.com>	2022-02-28 11:50:41 +01:00
Florian Weimer	d96d2995c1	Revert "Linux: Consolidate auxiliary vector parsing" ... This reverts commit 8c8510ab27. The revert is not perfect because the commit included a bug fix for _dl_sysdep_start with an empty argv, introduced in commit 2d47fa6862 ("Linux: Remove DL_FIND_ARG_COMPONENTS"), and this bug fix is kept. The revert is necessary because the reverted commit introduced an early memset call on aarch64, which leads to crash due to lack of TCB initialization.	2022-02-11 17:10:59 +01:00
Florian Weimer	8c8510ab27	Linux: Consolidate auxiliary vector parsing ... And optimize it slightly. The large switch statement in _dl_sysdep_start can be replaced with a large array. This reduces source code and binary size.
