| Proposal for adding SHT_RELR sections in generic-abi is at |
| https://groups.google.com/forum/#!topic/generic-abi/bX460iggiKg |
| |
| Experimental support for SHT_RELR sections is available in the aosp |
| gdb repository, with the section type and dynamic array tags defined |
| in the OS specific range. |
| |
| This patch moves those definitions to the generic range so we can load |
| binaries containing SHT_RELR sections created by the experimental support |
| in sys-devel/binutils. |
