## --oformat=binary overrides an ELF OUTPUT_FORMAT.

## LMA(.text)=0x100, LMA(.mysec)=0x108. The minimum LMA of all non-empty sections is 0x100.
## We place an output section at its LMA minus 0x100.
# RUN: echo 'SECTIONS { .text 0x100 : {*(.text)} .mysec ALIGN(8) : {*(.mysec*)} }' > %talign.lds

## The empty section .data is ignored when computing the file size.
# RUN: echo 'SECTIONS { .text : {*(.text .mysec*)} .data 0x100 : {keep = .;}}' > %tempty.lds
# RUN: ld.lld -T %tempty.lds %t --oformat binary -o %tempty

## NOBITS sections are ignored as well.
## Also test that SIZEOF_HEADERS evaluates to 0.
# RUN: echo 'SECTIONS { .text : {. += SIZEOF_HEADERS; *(.text .mysec*)} .data 0x100 (NOLOAD) : {BYTE(0)}}' > %tnobits.lds

## FIXME .mysec should be placed at file offset 1.
## This does not work because for a section without PT_LOAD, we consider LMA = VMA.
# RUN: echo 'SECTIONS { .text : {*(.text)} .mysec 0x8 : AT(1) {*(.mysec*)} }' > %tlma.lds
