Virtually the exact same for MIPS n32 ABI. Needs a 64bit kernel, needs a mips64-*-linux-gnu toolchain, but the output is a hybrid 32bit/64bit binary. I wonder if procps ever resolved that PAGE_SIZE mess internally when we brought the o32/n32/n64 mess to light with its author? -- Joshua Kinard Gentoo/MIPS kumba@g.o 4096R/D25D95E3 2011-03-28 "The past tempts us, the present confuses us, the future frightens us.
