# SMALL_DATA_CTOR - .ctors contains small data.
# SMALL_DATA_DTOR - .dtors contains small data.
# DATA_ADDR - if end-of-text-plus-one-page isn't right for data start

# INPUT_FILES - INPUT command of files to always include
# WRITABLE_RODATA - if set, the .rodata section should be writable
# INIT_START, INIT_END - statements just before and just after

#
# When adding sections, do note that the names of some sections are used
