Subject: [PATCH 081/123] LoongArch: The symbol got type can only be obtained
|
||
|
|
after initialization
|
||
|
|
|
||
|
|
When scanning relocations and determining whether TLS type transition is
|
||
|
|
possible, it will try to obtain the symbol got type. If the symbol got
|
||
|
|
type record has not yet been allocated space and initialized, it will
|
||
|
|
cause ld to crash. So when uninitialized, the symbol is set to GOT_UNKNOWN.
