[PATCH] more robust check for multiplier in addressing mode when determining the costs

2013-10-22 Thread Igor Shevlyakov
I'm working on a chip with some unusual addressing modes. it does have [base_rage+msize*index_reg] and one can't omit base_reg like on x86. But when ivopts tries to calculate the costs of different addressing modes it only checks [mult*reg] to determine allowable multipliers. I modified multiplier_
