`.data32.rodata`	Holds `__data32` constant data.
`DIFUNCT`	Holds pointers to code, typically C++ constructors, that should be executed by the system startup code before `main` is called.
`EARLYDIFUNCT`	Holds pointers to code objects that require early initialization, typically stream I/O, that should be executed by the system startup code before `main` is called.
`.exceptvect`	Holds the exception vectors.
`HEAP`	Holds the heap used for dynamically allocated data.
`.iar.dynexit`	Holds the `atexit` table.
`.iar.locale_table`	Holds the locale table for the selected locales.
`.init_array`	Holds a table of dynamic initialization functions.
`__iar_tls$$DATA`	Holds initial values for TLS variables.
`__iar_tls$$INITDATA`	Holds initial values for the TLS area.
`.inttable`	Holds all interrupt vectors except for non-maskable interrupts
`ISTACK`	Holds the supervisor mode stack.
`.preinit_array`	Holds a table of dynamic initialization functions.
`.resetvect`	Holds the reset vectors.
`.sbrel.bss`	Holds zero-initialized `__sbrel` static and global variables.
`.sbrel.data`	Holds `__sbrel` static and global initialized variables.
`.sbrel.data_init`	Holds initial values for `__sbrel.data` sections when the linker directive `initialize` is used.
`.sbrel.noinit`	Holds `__no_init __sbrel` static and global variables.
`.switch.rodata`	Holds tables for switch statements.
`.tbss`	Holds thread-local zero-initialized static and global variables for the primary thread.
`.tdata`	Holds thread-local initialized static and global variables for the primary thread.
`.text`	Holds the program code.
`.textrw`	Holds `__ramfunc` declared program code.
`.textrw_init`	Holds initializers for the `.textrw` declared section.
`USTACK`	Holds the user mode stack.

Table 90. Section summary

Other sections

In addition to the ELF sections used for your application, the tools use a number of other ELF sections for a variety of purposes:

Sections starting with .debug generally contain debug information in the DWARF format
Sections starting with .iar.debug contain supplemental debug information in an IAR format
The section .comment contains the tools and command lines used for building the file
Sections starting with .rel or .rela contain ELF relocation information
The section .symtab contains the symbol table for a file
The section .strtab contains the names of the symbol in the symbol table
The section .shstrtab contains the names of the sections.
