## We fail to flag the STT_NOTYPE reference. This usually happens with hand-written
## assembly because compiler-generated code properly sets symbol types.

## Overriding a TLS definition with a non-TLS definition does not make sense.
# RUN: not ld.lld --defsym tls1=42 %t.o -o /dev/null 2>&1 | FileCheck %s

## Part of PR36049: This should probably be allowed.
# RUN: not ld.lld --defsym tls1=tls2 %t.o -o /dev/null 2>&1 | FileCheck %s

## An undefined symbol in module-level inline assembly of a bitcode file
## is considered STT_NOTYPE. We should not error.
