Linker Timer Optimization

joy liu

I am looking for a linker command user manual to understand a set of linker command files created by someone who left the company while ago.

We are using ARM compiler v4.7 for the software and it has been worked fine until we upgraded compiler to v4.9 with linker timer optimization on, having opt_level=4. When using compiler v4.9 with opt_level=2, the software is working fine. But with opt_level=4, the software has memory access exceptions in different places, depending on how faster to stop the execution. I am quite new to compiler and linker and need to understand how a set of linker commands works in order to futher debug this memory access issue.

Any helps are high appreciated.

Hi Joy,

This document contains all the compiler and linker options documentation for 4.9.

http://www.ti.com/lit/ug/spnu151g/spnu151g.pdf

This references all the options so you can reverse engineer what has been done.

Best regards,

Hi Joy,

I just saw this post and understand it is unanswered. There is also a lot more information on the linker command file usage, absolute lister, and hex470 in the assembly language users guide. This is the one I always use: http://www.ti.com/general/docs/lit/getliterature.tsp?baseLiteratureNumber=spnu118&fileType=pdf

Please let us know if you have what you need.
