虽然说Keil编译出来的Coremark偏低,但是我还是喜欢Keil,衡量好坏不能单从Coremark来说,就如手机不能只靠小米兔兔说啊.当然IAR效率高也得益于他激进的更新,萝卜青菜各有所热爱吧.
Keil 最高优化,-O3,Optimize for time,Use Cross-Module Optimization,V5.06编译器,Use MicroLib.
Program Size: Code=17486 RO-data=898 RW-data=148 ZI-data=6308
2K performance run parameters for coremark.
CoreMark Size : 666
Total ticks : 13748
Total time (secs): 13.748000
Iterations/Sec : 872.854233
Iterations : 12000
Compiler version : -O3,Optimize for time,Use Cross-Module Optimization,V5.06
Compiler flags : N
Memory location : STACK
seedcrc : 0xe9f5
[0]crclist : 0xe714
[0]crcmatrix : 0x1fd7
[0]crcstate : 0x8e3a
[0]crcfinal : 0xd340
Correct operation validated. See readme.txt for run and reporting rules.
CoreMark 1.0 : 872.854233 / -O3,Optimize for time,Use Cross-Module Optimization,V5.06 N / STACK
IAR下测试,最高优化,速度优化,不约束体积,函数内联,指令调度优化.编译后,看来占用RAM确实很大.

所以我综合考虑还是用一直习惯的Keil吧.
