gcc.c (sanitize_spec_function): Handle SANITIZE_FLOAT_DIVIDE.
* gcc.c (sanitize_spec_function): Handle SANITIZE_FLOAT_DIVIDE.
* builtins.def: Initialize builtins even for SANITIZE_FLOAT_DIVIDE.
* flag-types.h (enum sanitize_code): Add SANITIZE_FLOAT_DIVIDE.
* opts.c (common_handle_option): Add -fsanitize=float-divide-by-zero.
c-family/
* c-ubsan.c (ubsan_instrument_division): Handle REAL_TYPEs. Perform
INT_MIN / -1 sanitization only for integer types.
c/
* c-typeck.c (build_binary_op): Call ubsan_instrument_division
also when SANITIZE_FLOAT_DIVIDE is on.
cp/
* typeck.c (cp_build_binary_op): Call ubsan_instrument_division
even when SANITIZE_FLOAT_DIVIDE is on. Set doing_div_or_mod even
for non-integer types.
testsuite/
* c-c++-common/ubsan/div-by-zero-5.c: Fix formatting.
