Hex6x .c6xabi.exidx extraction from library with linker command file specification

I'm attempting to split out a library into a separate b0* file with other sections (.text, etc).  I'm doing this by creating separate sections to keep common code together, while separating non-common code for two libraries. 

Problem:

.c6xabi.exidx will not split out.  Whilst,  .c6xabi.extab, does split properly.   Why does the exidx (exception table indices) not split, but the table (un-wind code entries) itself will? 

Linker error:

"../finallnk.cmd", line 72: warning #10068-D: no matching section

relevant portion of my Linker Command File

.c6xabi.exidx  

.split_me_exidx { -l=myLibrary.lib(.c6xabi.exidx) }

.c6xabi.extab 

.split_me_extab { -l=myLibrary.lib(.c6xabi.extab) }

Generated map file

.c6xabi.exidx   (this demonstrates it didn't work )

            e0062608 00000110                         : Executive.obj (.c6xabi.exidx:.text)

...

.split_me_extab         (this worked!)

Any ideas? 

Thanks
