Subject: [PATCH 079/123] LoongArch: ld:Report an error when seeing an
|
||
|
|
unrecognized relocation
|
||
|
|
|
||
|
|
If we generate an object file using an assembler with the new
|
||
|
|
relocations added, and then linking those files with an older
|
||
|
|
linker, the link will still complete and the linked file will
|
||
|
|
be generated.
|
||
|
|
In this case we should report an error instead of continuing
|
||
|
|
the linking process.
