From b221bff7c7ca20d961a7e6b663a545384054a5be Mon Sep 17 00:00:00 2001 From: Lulu Cai Date: Fri, 19 Apr 2024 10:24:52 +0800 Subject: 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. --- bfd/elfnn-loongarch.c | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) diff --git a/bfd/elfnn-loongarch.c b/bfd/elfnn-loongarch.c index 7b493f6..fe780e3 100644 --- a/bfd/elfnn-loongarch.c +++ b/bfd/elfnn-loongarch.c @@ -683,7 +683,14 @@ loongarch_can_trans_tls (bfd *input_bfd, if (!
