match: Improve `(a != b) ? (a + b) : (2 * a)` pattern [PR19832]
In the testcase provided, we would match f_plus but not g_plus
due to a missing `:c` on the plus operator. This fixes the oversight
there.
Note this was noted in https://github.com/llvm/llvm-project/issues/76318 .
Committed as obvious after bootstrap/test on x86_64-linux-gnu.
PR tree-optimization/19832
gcc/ChangeLog:
* match.pd (`(a != b) ? (a + b) : (2 * a)`): Add `:c`
on the plus operator.
gcc/testsuite/ChangeLog:
* gcc.dg/tree-ssa/phi-opt-same-2.c: New test.
