URL: https://github.com/llvm/llvm-project/commit/53154a83aee0ce969dc07e7168b3914ca1025030 DIFF: https://github.com/llvm/llvm-project/commit/53154a83aee0ce969dc07e7168b3914ca1025030.diff LOG: [ARM][clang] Add back branch protection tests When committing the PACBTI-M frontend support patch (https://reviews.llvm.org/D112421), the tests in arm-invalid-branch-protection.c were failing on certain test setups, so it was removed to make the llvm test suite pass. The fix is to require arm-registered-target. This patch is part of a series that adds support for the PACBTI-M extension of the Armv8.1-M architecture, as detailed here: https://community.arm.com/arm-community-blogs/b/architectures-and-processors-blog/posts/armv8-1-m-pointer-authentication-and-branch-target-identification-extension The PACBTI-M specification can be found in the Armv8-M Architecture Reference Manual: https://developer.arm.com/documentation/ddi0553/latest Reviewed By: erichkeane Differential Revision: https://reviews.llvm.org/D115141 Added: clang/test/Frontend/arm-invalid-branch-protection.c Modified: Removed: ################################################################################ diff --git a/clang/test/Frontend/arm-invalid-branch-protection.c b/clang/test/Frontend/arm-invalid-branch-protection.c new file mode 100644 index 0000000000000..f7bbd5941b024 --- /dev/null +++ b/clang/test/Frontend/arm-invalid-branch-protection.c @@ -0,0 +1,7 @@ +// REQUIRES: arm-registered-target +// RUN: %clang -target arm-arm-none-eabi -mbranch-protection=pac-ret+b-key -c %s -o /dev/null 2>&1 | FileCheck %s +// RUN: %clang -target arm-arm-none-eabi -mbranch-protection=pac-ret+b-key+leaf -c %s -o /dev/null 2>&1 | FileCheck %s +// RUN: %clang -target arm-arm-none-eabi -mbranch-protection=bti+pac-ret+b-key -c %s -o /dev/null 2>&1 | FileCheck %s +// RUN: %clang -target arm-arm-none-eabi -mbranch-protection=bti+pac-ret+b-key+leaf -c %s -o /dev/null 2>&1 | FileCheck %s + +// CHECK: warning: invalid branch protection option 'b-key' in '-mbranch-protection={{[a-z+-]*}}' [-Wbranch-protection] _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
