URL: https://github.com/llvm/llvm-project/commit/d302398ff05f6d2bfbcb5c4fdafccf8a0e3b9875 DIFF: https://github.com/llvm/llvm-project/commit/d302398ff05f6d2bfbcb5c4fdafccf8a0e3b9875.diff LOG: hwasan: Update register-dump-read.c test to reserve x23 instead of x20. D90422 changed this test to write a fixed value into register x23 instead of x20, but it did not update the list of reserved registers. This meant that x23 may have been live across the register write, although this happens to not be the case with the current compiler. Fix the problem by updating the reserved register list. Added: Modified: compiler-rt/test/hwasan/TestCases/register-dump-read.c Removed: ################################################################################ diff --git a/compiler-rt/test/hwasan/TestCases/register-dump-read.c b/compiler-rt/test/hwasan/TestCases/register-dump-read.c index 8325857fa916..002c5dd5e1f9 100644 --- a/compiler-rt/test/hwasan/TestCases/register-dump-read.c +++ b/compiler-rt/test/hwasan/TestCases/register-dump-read.c @@ -1,11 +1,11 @@ -// RUN: %clang_hwasan -ffixed-x10 -ffixed-x20 -ffixed-x27 -O0 %s -o %t && not %run %t 2>&1 | FileCheck %s --check-prefixes=CHECK -// RUN: %clang_hwasan -ffixed-x10 -ffixed-x20 -ffixed-x27 -O1 %s -o %t && not %run %t 2>&1 | FileCheck %s --check-prefixes=CHECK -// RUN: %clang_hwasan -ffixed-x10 -ffixed-x20 -ffixed-x27 -O2 %s -o %t && not %run %t 2>&1 | FileCheck %s --check-prefixes=CHECK -// RUN: %clang_hwasan -ffixed-x10 -ffixed-x20 -ffixed-x27 -O3 %s -o %t && not %run %t 2>&1 | FileCheck %s --check-prefixes=CHECK +// RUN: %clang_hwasan -ffixed-x10 -ffixed-x23 -ffixed-x27 -O0 %s -o %t && not %run %t 2>&1 | FileCheck %s --check-prefixes=CHECK +// RUN: %clang_hwasan -ffixed-x10 -ffixed-x23 -ffixed-x27 -O1 %s -o %t && not %run %t 2>&1 | FileCheck %s --check-prefixes=CHECK +// RUN: %clang_hwasan -ffixed-x10 -ffixed-x23 -ffixed-x27 -O2 %s -o %t && not %run %t 2>&1 | FileCheck %s --check-prefixes=CHECK +// RUN: %clang_hwasan -ffixed-x10 -ffixed-x23 -ffixed-x27 -O3 %s -o %t && not %run %t 2>&1 | FileCheck %s --check-prefixes=CHECK // REQUIRES: aarch64-target-arch -// RUN: %clang_hwasan -ffixed-x10 -ffixed-x20 -ffixed-x27 -O2 %s -o %t && not %env_hwasan_opts=fast_unwind_on_fatal=true %run %t 2>&1 | FileCheck %s --check-prefixes=CHECK -// RUN: %clang_hwasan -ffixed-x10 -ffixed-x20 -ffixed-x27 -O2 %s -o %t && not %env_hwasan_opts=fast_unwind_on_fatal=false %run %t 2>&1 | FileCheck %s --check-prefixes=CHECK +// RUN: %clang_hwasan -ffixed-x10 -ffixed-x23 -ffixed-x27 -O2 %s -o %t && not %env_hwasan_opts=fast_unwind_on_fatal=true %run %t 2>&1 | FileCheck %s --check-prefixes=CHECK +// RUN: %clang_hwasan -ffixed-x10 -ffixed-x23 -ffixed-x27 -O2 %s -o %t && not %env_hwasan_opts=fast_unwind_on_fatal=false %run %t 2>&1 | FileCheck %s --check-prefixes=CHECK #include <stdlib.h> #include <stdio.h> _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
