Builds just fine in f17, http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=292256 WONTFIX for GCC 4.6/ARM support. |
Build of hercules-3.07-2.fc15 fails on armv7hl (gcc-4.6.1-9.fc15.0.arm5.armv7hl) with ... esame.c: In function 'z900_load_long_byte_register': esame.c:8001:1: error: unrecognizable insn: (insn 25 24 26 2 (set (subreg:SI (reg:DI 153 [ regs_7(D)->gr[r2_6].F.L.H.L.B.L ]) 0) (sign_extend:SI (mem/s:QI (plus:SI (mult:SI (reg:SI 152) (const_int 8 [0x8])) (reg/v/f:SI 144 [ regs ])) [0 regs_7(D)->gr[r2_6].F.L.H.L.B.L+0 S1 A64]))) esame.c:7999 -1 (nil)) esame.c:8001:1: internal compiler error: in extract_insn, at recog.c:2109 Jakub, please take this report rather as placeholder for other people seeing the same error, because - I don't have a armv7 system ready to provide the preprocessed sources or other outputs - it could be already fixed in gcc 4.7 (I saw similar reports in gcc bugzilla) - it's being built with a private gcc version not the Fedora one
