From the linker script we find that .text.* i.e all section with any suffix after .text.* is placed under .text section. We find that certain functions are suffixed to .text.xxxx as unique section names. We dont find the compiler option "-function-sections" in our compilation steps.

Из сценария компоновщика мы находим, что .text. * Вся секция с любым суффиксом после .text. * Помещается в раздел .text. Мы обнаруживаем, что некоторые функции суффиктируются в .text.xxxx как уникальные имена разделов. Мы не находим параметр компилятора «-function-sections» в наших этапах компиляции. – gsat
