From ab37e9a171794d3d1fdaa5eff93a61590e5cee8c Mon Sep 17 00:00:00 2001 From: Ryan Salsamendi Date: Sun, 11 Jun 2017 21:07:31 -0700 Subject: Add support for Undefined Behavior Sanitizer Initial support for undefined behavior sanitizer in ramstage. Enabling this will add -fsanitize=undefined to the compiler command line and link with ubsan.c in ramstage. Code with UB triggers a report with error, file, and line number, then aborts.
