This behavior was introduced by commit r15-7961-gdc47161c1f32c3, which enhanced alias analysis in ao_compare::compare_ao_refs, enabling the compiler to identify and optimize structurally identical functions. As a result, the compiler replaced insert_di_0_v2 with a tail call to insert_di_0, altering the expected test behavior. This patch adds -fno-ipa-icf to the test's dg-options to disable ICF, avoiding function merging and ensuring the test executes correctly. 2025-06-24 Jeevitha Palanisamy gcc/testsuite/ PR testsuite/119382 * gcc.target/powerpc/vsx-builtin-7.c: Add '-fno-ipa-icf' to dg-options.
