Subject: LoongArch: The symbol got type can only be obtained after initialization
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9055fbe5ffbbb8f7ea17d8e4c8ffdc0438038f67;p=thirdparty%2Fbinutils-gdb.git

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.
