nuudlman/llvm: llvm/test/tools/llvm-objdump/warn-on-out-of-range-start-stop-address.test

## This test checks warning messages if --start-address/--stop-address
## do not intersect with address ranges of sections that have the SHF_ALLOC
## flag.

# RUN: yaml2obj --docnum=1 %s -o %t
# RUN: yaml2obj --docnum=2 %s -o %t.2
# RUN: yaml2obj --docnum=3 %s -o %t.o
# RUN: yaml2obj --docnum=4 %s -o %t.3

## 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 |
# RUN: llvm-objdump --file-headers --start-address=0x1005 --stop-address=0x1006 %t 2>&1 \
# RUN:   | FileCheck %s --check-prefix=WARN

## - Range appears after any section:
##                  | range |
## | section |
# RUN: llvm-objdump --file-headers --start-address=0x1405 --stop-address=0x1406 %t 2>&1 \
# RUN:   | FileCheck %s --check-prefix=WARN

## - Range starts at 0. (--start-address defaults to 0).
# RUN: llvm-objdump --file-headers --stop-address=0x1000 %t 2>&1 \
# RUN:   | FileCheck %s --check-prefix=WARN-STOP-ONLY

## - Range ends at UINT64_MAX. (--stop-address defaults to UINT64_MAX)
# RUN: llvm-objdump --file-headers --start-address=0x1500 %t 2>&1 \
# RUN:   | FileCheck %s --check-prefix=WARN-START-ONLY

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

## - Ranges are identical:
## | range   |
## | section |
# RUN: llvm-objdump --file-headers --start-address=0x1000 --stop-address=0x1004 %t 2>&1 \
# RUN:   | FileCheck %s --implicit-check-not=warning:

## - Range is entirely within section:
##  | range |
## | section |
# RUN: llvm-objdump --file-headers --start-address=0x1001 --stop-address=0x1003 %t 2>&1 \
# RUN:   | FileCheck %s --implicit-check-not=warning:

## - Section is entirely within range:
## |   range   |
##  | section |
# RUN: llvm-objdump --file-headers --start-address=0xfff --stop-address=0x1005 %t 2>&1 \
# RUN:   | FileCheck %s --implicit-check-not=warning:

## - Section and range share same start, section larger:
## | range |
## | section |
# RUN: llvm-objdump --file-headers --start-address=0x1000 --stop-address=0x1003 %t 2>&1 \
# RUN:   | FileCheck %s --implicit-check-not=warning:

## - Section and range share same start, range larger:
## | range        |
## | section |
# RUN: llvm-objdump --file-headers --start-address=0x1000 --stop-address=0x1005 %t 2>&1 \
# RUN:   | FileCheck %s --implicit-check-not=warning:

## - Section and range share same end, section larger:
##   | range |
## | section |
# RUN: llvm-objdump --file-headers --start-address=0x1001 --stop-address=0x1004 %t 2>&1 \
# RUN:   | FileCheck %s --implicit-check-not=warning:

## - Section and range share same end, range larger:
## | range    |
##  | section |
# RUN: llvm-objdump --file-headers --start-address=0xfff --stop-address=0x1004 %t 2>&1 \
# RUN:   | FileCheck %s --implicit-check-not=warning:

## - Section and range partially overlap, range first:
## | range |
##   | section |
# RUN: llvm-objdump --file-headers --start-address=0xfff --stop-address=0x1003 %t 2>&1 \
# RUN:   | FileCheck %s --implicit-check-not=warning:

## - Section and range partially overlap, section first:
##       | range |
## | section |
# RUN: llvm-objdump --file-headers --start-address=0x1001 --stop-address=0x1005 %t 2>&1 \
# RUN:   | FileCheck %s --implicit-check-not=warning:

## - Range starts before first section and ends after second:
## |            range               |
##   | section |    | section |
# RUN: llvm-objdump --file-headers --start-address=0xfff --stop-address=0x1405 %t 2>&1 \
# RUN:   | FileCheck %s --implicit-check-not=warning:

## Warn only for the input file that does not have the specified range.
# RUN: llvm-objdump --file-headers --start-address=0x2001 --stop-address=0x2005 %t %t.2 2>&1 \
# RUN:   | FileCheck %s --check-prefix=MULTI-INPUT

## Warn if the specified range is in a segment but not in any section.
# RUN: llvm-objdump --file-headers --start-address=0x1008 --stop-address=0x1009 %t 2>&1 \
# RUN:   | FileCheck %s --check-prefix=WARN

## Warning for --start-address/--stop-address works regardless of the other options used including --section.
# RUN: llvm-objdump --syms --section=.text2 --start-address=0x1004 --stop-address=0x1005 %t 2>&1 \
# RUN:   | FileCheck %s --check-prefix=WARN

## Sections without the SHF_ALLOC flag are ignored in address range calculation.
# RUN: llvm-objdump --file-headers --start-address=0x1 --stop-address=0x3 %t.3 2>&1 \
# RUN:   | FileCheck %s --check-prefix=WARN

## No warning for relocatable objects.
# RUN: llvm-objdump --file-headers --start-address=0x1004 --stop-address=0x1005 %t.o 2>&1 \
# RUN:   | FileCheck %s --implicit-check-not=warning:

## No warning if neither --start-address nor --stop-address are specified.
# RUN: llvm-objdump --file-headers %t 2>&1 | FileCheck %s --implicit-check-not=warning:

# WARN: warning: {{.*}}: no section overlaps the range {{.*}} specified by --start-address/--stop-address
# WARN-STOP-ONLY: warning: {{.*}}: no section has address less than 0x1000 specified by --stop-address
# WARN-START-ONLY: warning: {{.*}}: no section has address greater than or equal to 0x1500 specified by --start-address

# MULTI-INPUT: file format
# MULTI-INPUT: warning: {{.*}}: no section overlaps the range [0x2001,0x2005) specified by --start-address/--stop-address
# MULTI-INPUT: file format
