-// A Load Configuration is a data structure for x86 containing an address of the
-// SEH handler table. The Data Directory in the file header points to a load
-// configuration. Technically that indirection is not needed but exists for
-// historical reasons.
-//
-// If the file being handled has .sxdata section containing SEH handler table,
-// this pass will create a Load Configuration atom.
