## In this test we check how the unwind information is dumped with the use of --unwind.
|
||
|
|
|
||
|
|
## First, check that both llvm-readobj and llvm-readelf are able to dump a valid unwind information.
|
||
|
|
## Check that the output is the same for these tools.
|
||
|
|
## The memory size of the PT_GNU_EH_FRAME equals its file size and they both are equal to 0x3c.
|
||
|
|
## 0x3c is the size of the .eh_frame_hdr section.
|
||
|
|
# RUN: yaml2obj --docnum=1 %s -DMEMSIZE=0x3c -DFILESIZE=0x3c -o %t1.valid
