## This test shows that llvm-objcopy does not baulk at overlapping sections.
|
||
|
|
## These don't really make sense, but the tool should still handle invalid
|
||
|
|
## inputs somehow.
|
||
|
|
# RUN: yaml2obj %s -o %t.o
|
||
|
|
|
||
|
|
## Check that the contents are as expected before the copy.
|
||
|
|
# RUN: llvm-readobj -x .first -x .second %t.o | FileCheck %s --check-prefix=CONTENTS
|
||
|
|
|
||
|
|
## Now check that the section contents are still correct after the copy.
|
||
|
|
## Also characterize the behavior of llvm-objcopy in that it "unoverlaps" the
|
||
|
|
## two sections.
