Imagine we have a YAML declaration of few sections: `foo1`, `<unnamed 2>`, `foo3`, `foo4`. To put them into segment we can do (1*): ``` Sections: - Section: foo1 - Section: foo4 ``` or we can use (2*): ``` Sections: - Section: foo1 - Section: foo3 - Section: foo4 ``` or (3*) : ``` Sections: - Section: foo1 ## "(index 2)" here is a name that we automatically created for a unnamed section. - Section: (index 2) - Section: foo3 - Section: foo4 ``` It looks really confusing that we don't have to list all of sections. At first I've tried to make this rule stricter and report an error when there is a gap (i.e. when a section is included into segment, but not listed explicitly). This did not work perfect, because such approach conflicts with unnamed sections/fills (see (3*)). This patch drops "Sections" key and introduces 2 keys instead: `FirstSec` and `LastSec`. Both are optional. Differential revision: https://reviews.llvm.org/D90458
