--- Comment #5 from Kito Cheng <kito at gcc dot gnu.org> ---
I thought either -fbuilding-libgcc or -fno-builtin can suppress that, but I
realized it's just cause by GCC introduce a new MULT during optimization after
reading dump...so another work around by command line option is adding
`-fno-ssa-phiopt` for this file.
