http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46934 --- Comment #3 from Chung-Lin Tang 2011-03-23 14:48:38 UTC --- Please disregard the above comments, I think this is an ARM backend problem after all.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46934 Chung-Lin Tang changed: What|Removed |Added CC||cltang at gcc dot gnu.org --- Comment #2 from Chung-Lin Tang 2010-12-23 10:09:29 UTC --- I think this can be solved by changing the predicate of operand[2] in *thumb1_addsi3 to "reg_or_int_operand". This allows later passes like reload to do its job. However, after the above change, I see another ICE during reload: h.c:16:1: error: unrecognizable insn: (insn 88 3 6 2 (set (reg:SI 3 r3) (const_int 2147483648 [0x8000])) h.c:5 -1 (nil)) h.c:16:1: internal compiler error: in extract_insn, at recog.c:2127 This turns out to be because, the generic 'general_operand' predicate used in thumb1_movsi_insn does a "trunc_int_for_mode (INTVAL(op), mode) == INTVAL(op)" test, and 0x8000 (2147483648) gets negated due to the sign-extension in trunc_int_for_mode(), failing the equality test: trunc_int_for_mode(2147483648, SImode) == -2147483648 (0x8000) We can probably fix this by using another ARM predicate in this case, though this boundary case of trunc_int_for_mode() is troubling, as the above truncate-and-test-for-equality idiom seems quite common in the compiler.
