Tim Northover 81271b4305 ARM: don't mangle DAG constant if it has more than one use ... The basic optimisation was to convert (mul $LHS, $complex_constant) into roughly "(shl (mul $LHS, $simple_constant), $simple_amt)" when it was expected to be cheaper. The original logic checks that the mul only has one use (since we're mangling $complex_constant), but when used in even more complex addressing modes there may be an outer addition that can pick up the wrong value too. I *think* the ARM addressing-mode problem is actually unreachable at the moment, but that depends on complex assessments of the profitability of pre-increment addressing modes so I've put a real check in there instead of an assertion. llvm-svn: 259228		2016-01-29 19:18:46 +00:00
