`--gnu_linker_defined_syms`

This option enables support for the GNU equivalent of input section symbols.

Table 2. GNU equivalent of input sections
GNU Symbol	ARM symbol	Description
`__start_SectionName`	`SectionName$$Base`	Address of the start of the consolidated section called `SectionName`.
`__stop_SectionName`	`SectionName$$Limit`	Address of the byte beyond the end of the consolidated section called `SectionName`

A reference to SectionName by a GNU input section symbol is sufficient for armlink to prevent the section from being removed as unused.
A reference by an ARM input section symbol is not sufficient to prevent the section from being removed as unused.

This option is enabled by default when you specify --arm_linux. It is disabled by default in all other cases.

Usage

If you want GNU-style behavior when treating the ARM symbols SectionName$$Base and SectionName$$Limit, then specify --gnu_linker_defined_syms.
