## do not intersect with address ranges of sections that have the SHF_ALLOC
|

## flag.

## Warn if no section covers any part of the specified range.
|
||
|
|
|
||
|
|
## - Section ends at start of range:
|

|
|
## | range |
|
||
|
|
## | section |
|
||
|
|
# RUN: llvm-objdump --file-headers --start-address=0x1004 --stop-address=0x1006 %t 2>&1 \
|
||
|
|
# RUN: | FileCheck %s --check-prefix=WARN
|
||
|
|
|
||
|
|
## - Range is between two sections:
|
||
|
|
## | range |
|
||
|
|
## | section | | section |

|
|
|
||
|
|
## No warning if a section covers at least part of the specified range.
