# REQUIRES: x86

## Test that lazy symbols in a section group can be demoted to Undefined,
|
|
## so that we can report a "discarded section" error.

# RUN: llvm-mc -filetype=obj -triple=x86_64 %s -o %t.o

# RUN: echo '.globl f1, foo; f1: call foo; \

# RUN: llvm-mc -filetype=obj -triple=x86_64 - -o %t1.o
|
|
|
|
## Test the case when the symbol causing a "discarded section" is ordered
|
|
## *before* the symbol fetching the lazy object.
|
|
## The test relies on the symbol table order of llvm-mc (lexical), which will
|
|
## need adjustment if llvm-mc changes its behavior.
