Hello! Renaming UNSPEC_MOVNT to UNSPEC_MOVNTI was not a good idea, since it caused [1]: prefetch-8.c: In function ‘test’: prefetch-8.c:16:1: error: unrecognizable insn: (insn 15 14 16 4 (set (mem:SI (plus:SI (mult:SI (reg/v:SI 64 [ i ]) (const_int 4 [0x4])) (reg/f:SI 65)) [2 MEM[symbol: a, index: i_9, step: 4, offset: 0B]+0 S4 A32]) (unspec:SI [ (reg:SI 66) ] UNSPEC_MOVNT)) prefetch-8.c:15 -1 (nil)) prefetch-8.c:16:1: internal compiler error: in extract_insn, at recog.c:2137 Fixed by attached patch that also added missing modes to STORENT_MODE mode iterator. 2011-11-20 Uros Bizjak <ubizjak@gmail.com> * config/i386/i386.md (UNSPEC_MOVNTI): Remove. (UNSPEC_MOVNTQ): New unspec. * config/i386/mmx.md (sse_movntdi): Use UNSPEC_MOVNTQ instead of UNSPEC_MOVNT. * config/i386/sse.md (sse2_movnti<mode>): Use UNSPEC_MOVNT instead of UNSPEC_MOVNTI. (STORENT_MODE): Add DI and V4DI modes. Patch was tested on x86_64-pc-linux-gnu {,-m32} and committed to mainline SVN. [1] http://gcc.gnu.org/ml/gcc-testresults/2011-11/msg02046.html Uros.
