For other sections, the mapping is as follows: .xxx -> .ARM.exidx.xxx So, if there is an ".ARM.exidx.text", it must be from ".text", and adding ".ARM.exidx.text" will not cause any other harm. We only need to ensure that the merging of the ".text*" sections is consistent with the merging of the ".ARM.exidx*" sections, and the current patch already satisfies this requirement. I have no other questions about this, so: Reviewed-by: Xie Yuanbin Tested-by: Xie Yuanbin Also, don't forget to submit your patch to Russell's patch tracker: Link: https://www.armlinux.org.uk/developer/patches/ Thanks.
