# REQUIRES: x86
## Test file offsets of SHT_NOBITS sections and of the sections following them
## in the same PT_LOAD.

# RUN: rm -rf %t && split-file %s %t && cd %t
# RUN: llvm-mc -filetype=obj -triple=x86_64 a.s -o a.o
# RUN: llvm-mc -filetype=obj -triple=x86_64 b.s -o b.o

## If a SHT_NOBITS section is the only section of a PT_LOAD segment,
## p_offset will be set to the sh_offset field of the section. Check we align
## sh_offset to sh_addr modulo max-page-size, so that p_vaddr=p_offset (mod
## p_align).
