// REQUIRES: amdgpu-registered-target
[clang][NewPM] Add -fno-experimental-new-pass-manager to tests As per the discussion on D58375, we disable test that have optimizations under the new PM. This patch adds -fno-experimental-new-pass-manager to RUNS that: - Already run with optimizations (-O1 or higher) that were missed in D58375. - Explicitly test new PM behavior along side some new PM RUNS, but are missing this flag if new PM is enabled by default. - Specify -O without the number. Based on getOptimizationLevel(), it seems the default is 2, and the IR appears to be the same when changed to -O2, so update the test to explicitly say -O2 and provide -fno-experimental-new-pass-manager`.

Avoid creating conditional cleanup blocks that contain only @llvm.lifetime.end calls When a non-extended temporary object is created in a conditional branch, the lifetime of that temporary ends outside the conditional (at the end of the full-expression). If we're inserting lifetime markers, this means we could end up generating if (some_cond) { lifetime.start(&tmp); Tmp::Tmp(&tmp); } // ... if (some_cond) { lifetime.end(&tmp); } ... for a full-expression containing a subexpression of the form `some_cond ? Tmp().x : 0`. This patch moves the lifetime start for such a temporary out of the conditional branch so that we don't need to generate an additional basic block to hold the lifetime end marker. This is disabled if we want precise lifetime markers (for asan's stack-use-after-scope checks) or of the temporary has a non-trivial destructor (in which case we'd generate an extra basic block anyway to hold the destructor call).
