Subject: [PATCH] kasan: add __asan_report_loadN/storeN_noabort callbacks
Date: Fri, 19 Jan 2018 18:44:22 +0100 [thread overview]
Message-ID: <891fbd1fe77f46701fb1958e77bdd89651c12643.1516383788.git.andreyknvl@google.com> (raw)
Instead of __asan_report_load_n_noabort and __asan_report_store_n_noabort
callbacks Clang emits differently named __asan_report_loadN_noabort and
__asan_report_storeN_noabort (similar to __asan_loadN/storeN_noabort, whose
names both GCC and Clang agree on).
Add callback implementation for __asan_report_loadN/storeN_noabort.
