Description Scott Gary

Build Identifier: 

If C++ exception support is enabled for the TI compiler these two sections get generated: .ARM.exidx and .ARM.extab.  These sections are not placed in the linker command files, resulting in placement warnings, and in some cases (depending on default location) relocation overflow warnings.  (Tried this on both ARM9 and Cortex M3.)  Placement of these two sections should be added to the linker command files.

Reproducible: Always

Steps to Reproduce:
1.Build a C++ project (like the SYS/BIOS bigtime example)
2.Add some code to the .cpp file that does a throw()/catch()
3.Update the compiler language options to specify "Enable C++ exeception handling", and (if necessary) "Allow extern C functions to propagate exceptions" [under Properties->Build->TMS470 Compiler->Language Options]
4.Rebuild the project, note the warnings about new output sections without a SECTIONS specification

The bug is fixed in xdctargets-g01 (3.25 stream). If we need to backport the
fix to 3.23, the field Whiteboard should be set accordingly.
