Hi All,
The following patch has been tested on powerpc64le-linux and verified it's
fixed.
The test vsx-builtin-7.c was failing on powerpc64le-linux due to identical
function detection by ICF. This behavior was introduced by commit
r15-7961-gdc47161c1f32c3, which improved alias analysis in
ao_compare::compare_ao_refs, allowing the compiler to recognize and optimize
structurally identical functions.
The option -fno-ipa-icf is required because insert_di_0_v2 and insert_di_0 are
identified as equivalent, causing the compiler to replace insert_di_0_v2 with a
tail call to insert_di_0.
To prevent this optimization from altering the test behavior, explicitly disable
ICF by adding -fno-ipa-icf to the test options.
