From 3ac72d80925e1bc74dfafec727263e4ae45d14fd Mon Sep 17 00:00:00 2001 From: Manoj Gupta Date: Wed, 27 Sep 2017 17:36:25 +0000 Subject: [ARM] builtins: Replace abort by assert in clear_cache. Summary: __builtion___clear_cache maps to clear_cache function. On Linux, clear_cache functions makes a syscall and does an abort if syscall fails. Replace the abort by an assert so that non-debug builds do not abort if the syscall fails. Fixes PR34588.
