Summary of sections

In this section:

The compiler places code and data into sections. Based on a configuration specified in the linker configuration file, ILINK places sections in memory.

This table lists the ELF sections and blocks that are used by the IAR build tools:

Section	Description
`.bss`	Holds zero-initialized static and global variables.
`CSTACK`	Holds the stack used by C or C++ programs.
`.cstartup`	Holds the startup code.
`.data`	Holds static and global initialized variables.
`.data_init`	Holds initial values for `.data` sections when the linker directive `initialize` is used.
`HEAP`	Holds the heap.
`.iar.dynexit`	Holds the `atexit` table.
`.iar.locale_table`	Holds the locale table for the selected locales.
`__iar_tls$$DATA`	Holds the TLS area for the primary thread.
`__iar_tls$$INITDATA`	Holds initial values for the TLS area.
`.init_array`	Holds a table of dynamic initialization functions.
`.itim`	Holds functions and variables for the SiFive ITIM RAM area.
`.jumptable`	Holds jump tables for switch statements.
`.mtext`	Holds `__machine` interrupt functions.
`.noinit`	Holds `__no_init` static and global variables.
`.preinit_array`	Holds a table of dynamic initialization functions.
`.rodata`	Holds constant data.
`.stext`	Holds `__supervisor` interrupt functions.
`.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.
`.utext`	Holds `__user` interrupt functions.

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.
