PR14306: Move -fbounds-checking to -fsanitize=bounds. llvm-svn: 168510
2012-11-23 18:39:49 +08:00
// RUN: %clang -fsanitize=bounds -### -fsyntax-only %s 2> %t
// RUN: FileCheck -check-prefix=CHECK < %t %s
Split -fsanitize=bounds to -fsanitize=array-bounds (for the frontend-inserted check using the ubsan runtime) and -fsanitize=local-bounds (for the middle-end check which inserts traps). Remove -fsanitize=local-bounds from -fsanitize=undefined. It does not produce useful diagnostics and has false positives (PR17635), and is not a good compromise position between UBSan's checks and ASan's checks. Map -fbounds-checking to -fsanitize=local-bounds to restore Clang's historical behavior for that flag. llvm-svn: 193205

// CHECK: "-fsanitize=array-bounds,local-bounds"
add -fbounds-checking option. When enabled, clang generates bounds checks for array and pointers dereferences. Work to follow in LLVM's backend. OK'ed by Chad; thanks for the review. llvm-svn: 156431
