Thanks, Aleksey. Sorry for breaking the build. That change looks good to me.

ILW = Build failure, on x86_32, no workaround = HMH = P1

There is mulI_eReg, I wonder if that should be the used in x86_32.ad.

mulI_rReg is declared in x86_64.ad, and is not accessible from x86_32.ad: src/hotspot/cpu/x86/x86_64.ad 8128:instruct mulI_rReg(rRegI dst, rRegI src, rFlagsReg cr)
