## 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]]': SHT_DYNAMIC section with index 1 is not contained within the PT_DYNAMIC segment
