| 23 | # This script handles target configuration for gold. This is shell |
| 24 | # code invoked by the autoconf generated configure script. Putting |
| 25 | # this in a separate file lets us skip running autoconf when modifying |
| 26 | # target specific information. |
| 27 | |
| 28 | # This file switches on the shell variable ${targ}, which is a |
| 29 | # canonicalized GNU configuration triplet. It sets the following |
| 30 | # shell variables: |
| 31 | |
| 32 | # targ_obj object file to include in the link, with no extension |
| 33 | # targ_extra_obj extra object file to include |
| 34 | # targ_machine ELF machine code for this target |
| 35 | # targ_size size of this target--32 or 64 |
| 36 | # targ_extra_size extra targ_size setting for the target |
| 37 | # targ_big_endian whether the target is big-endian--true or false |
| 38 | # targ_extra_big_endian extra targ_big_endian setting for the target |
| 39 | # targ_osabi EI_OSABI value |
| 40 | |
| 41 | # If the target is not recognized targ_obj is set to "UNKNOWN". |
