...be that symbol "i" in the assembler source: .type i, at object # @i .section .tdata,"awT", at progbits .globl i .align 4 i: .long 7 # 0x7 .size i, 4 ... is given ELF symbol type STT_TLS by gcc's assembler, but STT_OBJECT by clang's assembler. I think this used to work, a few weeks ago. Has anything changed in this are recently? Thanks, Jay.

The .type directive should probably specify type "tls_object" rather than just "object". But I think gas infers that this is a TLS symbol anyway, because it is mentioned in TLS-related relocations. See this t...
