Subject: TableGen/CodeEmitterGen.cpp: Fix an expression of generating bitmask.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=89d8139d3706270ec99b3722f273a34af61b4644;p=oota-llvm.git

TableGen/CodeEmitterGen.cpp: Fix an expression of generating bitmask.

~0U might be i32 on 32-bit hosts, then (uint64_t)~0U might not be expected as (i64)0xFFFFFFFF_FFFFFFFF, but as (i64)0x00000000_FFFFFFFF.
