Compiler projects using llvm
## This test shows that llvm-objdump can handle sections with the same address
## when symbols in those sections are referenced. In the past, the section
## picked was non-deterministic, resulting in different symbols being found for
## the section. The test uses YAML for the input, as we need a fully linked ELF
## to reproduce the original failure.

## Two empty sections, one with symbol in, one without.
# RUN: yaml2obj %s --docnum=1 -o %t1 -D SIZE1=0 -D SIZE2=0 -D SECTION=.second -D INDEX=SHN_ABS
# RUN: llvm-objdump -d %t1 | FileCheck %s --check-prefix=TARGET
# RUN: yaml2obj %s --docnum=1 -o %t2 -D SIZE1=0 -D SIZE2=0 -D SECTION=.first -D INDEX=SHN_ABS
# RUN: llvm-objdump -d %t2 | FileCheck %s --check-prefix=TARGET

## Two sections, one empty with symbol, other non-empty, without symbol.
# RUN: yaml2obj %s --docnum=1 -o %t3 -D SIZE1=1 -D SIZE2=0 -D SECTION=.second -D INDEX=SHN_ABS
# RUN: llvm-objdump -d %t3 | FileCheck %s --check-prefix=TARGET
# RUN: yaml2obj %s --docnum=1 -o %t4 -D SIZE1=0 -D SIZE2=1 -D SECTION=.first -D INDEX=SHN_ABS
# RUN: llvm-objdump -d %t4 | FileCheck %s --check-prefix=TARGET

## Fall back to absolute symbol if no symbol found in candidate sections.
# RUN: yaml2obj %s --docnum=1 -o %t5 -D SIZE1=1 -D SIZE2=0 -D SECTION=.caller -D INDEX=SHN_ABS
# RUN: llvm-objdump -d %t5 | FileCheck %s --check-prefix=ABSOLUTE

## Show that other symbols with reserved st_shndx values are treated as absolute
## symbols.
# RUN: yaml2obj %s --docnum=1 -o %t6 -D SIZE1=1 -D SIZE2=0 -D SECTION=.caller -D INDEX=SHN_LOPROC
# RUN: llvm-objdump -d %t6 | FileCheck %s --check-prefix=ABSOLUTE

## Print no target if no symbol in section/absolute symbol found.
# RUN: llvm-objcopy %t5 %t7 -N other
# RUN: llvm-objdump -d %t7 | FileCheck %s --check-prefix=FAIL

# TARGET:   callq 0x5 <target>
# ABSOLUTE: callq 0x5 <other+0x5>
# FAIL:     callq 0x5{{$}}
