# REQUIRES: x86

## NOTE: Here we check that the first non-header section -- __text -- appears
|
|
|
|
|
## *exactly* `-headerpad` bytes from the end of the header. ld64 actually
|
|
|
|
|
## starts laying out the non-header sections in the __TEXT segment from the end
|
|
|
|
|
## of the (page-aligned) segment rather than the front, so its binaries
|
|
|
|
|
## typically have more than `-headerpad` bytes of actual padding. `-headerpad`
|
|
|
|
|
## just enforces a lower bound. We should consider implementing the same
|
|
|
|
|
## alignment behavior.
