--- Comment #18 from Robin Dapp <rdapp at gcc dot gnu.org> ---
Already in ifcvt we have:

_ifc__60 = .COND_ADD (_2, _6, MADPictureC1_lsm.10_25, MADPictureC1_lsm.10_25);

which we should not.  This is similar on riscv.

But during value numbering it still is

Value numbering stmt = _ifc__60 = .COND_ADD (_47, MADPictureC1_lsm.10_25, _6,
MADPictureC1_lsm.10_25);

so we originally created the right thing.
Hmm, no simplification is happening.  Is there still a swap somewhere that
should not be?
