Hi there, Currently the insn type of DSP-kind instructions like QSUB8 is alu_reg which is same as other normal instructions like SUB. In order to distinguish those DSP-kind instructions, this patch intends to replace current alu_reg with two sub categories alu_sreg and alu_dsp_reg. Meanwhile the alus_reg is renamed to alus_sreg in terms of consistence. This is the first patch of this series and intends to cover the files under gcc/config/arm. Tested with gcc regression, no new regressions. Is it ok to trunk? BR, Terry 2014-07-10 Terry Guo * config/arm/types.md (alu_reg): Replaced by alu_sreg and alu_dsp_reg.
