@llvm/pr-subscribers-clang Author: Pedro Lobo (pedroclobo) ChangesThe previous test incorrectly assumed 32-bit integers, leading to incorrect bit counts. This change updates the test result to assume 64-bit integers. Full diff: https://github.com/llvm/llvm-project/pull/152478.diff 1 Files Affected:

I don't really know how to run/verify these I've been relying on my editor's LSP. It flagged the failing |
|
just realised its not being run as c++ - just plain c :( Please can you add additional RUN lines? |
|
avx512vpopcntdqvl-builtins.c needs additional RUN lines as well |

Oh, I see you added the run lines in |
Some files containing `constexpr` tests did not have a C++ run line.

Adds missing C++ run lines to test files containing
constexprtests.Also adds missing 32/64-bit test coverage to the following tests:

_mm512_popcnt_epi64constexprtest that incorrectly assumed 32-bit integers, leading to incorrect bit counts. This change updates the test result to assume 64-bit integers.
