llvm/test/tools/llvm-readobj/ELF/dynamic-not-in-pt-dynamic.test

## Show that llvm-readobj/llvm-readelf tools sometimes can dump the
## dynamic table when it is not in a PT_DYNAMIC segment.

## Case 1: The dynamic table found using the dynamic program header is corrupted
##         (<size of data> % <size of dynamic entry> != 0). So the table is taken
##         from the section header.

# RUN: yaml2obj --docnum=1 %s -o %t1.o
# RUN: llvm-readobj --dynamic-table %t1.o 2>&1 \
# RUN:   | FileCheck -DFILE=%t1.o --check-prefixes=WARNING1,LLVM1 %s
# RUN: llvm-readelf --dynamic-table %t1.o 2>&1 \
# RUN:   | FileCheck -DFILE=%t1.o --check-prefixes=WARNING1,GNU1 %s

# WARNING1: warning: '[[FILE]]': The SHT_DYNAMIC section '.dynamic' is not contained within the PT_DYNAMIC segment
# WARNING1: warning: '[[FILE]]': invalid PT_DYNAMIC size (0x1){{$}}
# WARNING1: warning: '[[FILE]]': SHT_DYNAMIC section header and PT_DYNAMIC program header disagree about the location of the dynamic table
# WARNING1: warning: '[[FILE]]': PT_DYNAMIC dynamic table is invalid: SHT_DYNAMIC will be used

## Case 2: The dynamic table found using the dynamic program header is different from the
##         table found using the section header table.
