re PR sanitizer/83388 (reference statement index not found error with -fsanitize=null)
2017-12-15 Richard Biener <rguenther@suse.de>
PR lto/83388
* internal-fn.def (IFN_NOP): Add.
* internal-fn.c (expand_NOP): Do nothing.
* lto-streamer-in.c (input_function): Instead of removing
sanitizer calls replace them with IFN_NOP calls.
* gcc.dg/lto/pr83388_0.c: New testcase.
