ARM Compiler armlink User Guide : --info=topic[,topic,…]

--info=topic[,topic,…]

Prints information about specific topics. You can write the output to a text file using --list=file.

Syntax

--info=topic[,topic,…]

Where topic is a comma-separated list from the following topic keywords:

any

For sections placed using the .ANY module selector, lists:

The sort order.
The placement algorithm.
The sections that are assigned to each execution region in the order they are assigned by the placement algorithm.
Information about the contingency space and policy used for each region.

This keyword also displays additional information when you use the execution region attribute ANY_SIZE in a scatter file.

architecture

Summarizes the image architecture by listing the processor, FPU, and byte order.

common

Lists all common sections that are eliminated from the image. Using this option implies --info=common,totals.

compression

Gives extra information about the RW compression process.

debug

Lists all rejected input debug sections that are eliminated from the image as a result of using --remove. Using this option implies --info=debug,totals.

exceptions

Gives information on exception table generation and optimization.

inline

Lists all functions that are inlined by the linker, and the total number of inlines if --inline is used.

inputs

Lists the input symbols, objects and libraries.

libraries

Lists the full path name of every library automatically selected for the link stage.

You can use this option with --info_lib_prefix to display information about a specific library.

lto

Lists the commands sent to the link time optimizer.

You can use this option with --keep_intermediate=lto to reproduce link time optimization commands outside of armlink.

merge

Lists the const strings that are merged by the linker. Each item lists the merged result, the strings being merged, and the associated object files.

pltgot

Lists the PLT entries built for the executable or DLL.

sizes

Lists the code and data (RO Data, RW Data, ZI Data, and Debug Data) sizes for each input object and library member in the image. Using this option implies --info=sizes,totals.

stack

Lists the stack usage of all functions.

summarysizes

Summarizes the code and data sizes of the image.

summarystack

Summarizes the stack usage of all global symbols.

tailreorder

Lists all the tail calling sections that are moved above their targets, as a result of using --tailreorder.

totals

Lists the totals of the code and data (RO Data, RW Data, ZI Data, and Debug Data) sizes for input objects and libraries.

unused

Lists all unused sections that are eliminated from the user code as a result of using --remove. It does not list any unused sections that are loaded from the ARM C libraries.

unusedsymbols

Lists all symbols that have been removed by unused section elimination.

veneers

Lists the linker-generated veneers.

veneercallers

Lists the linker-generated veneers with additional information about the callers to each veneer. Use with --verbose to list each call individually.

veneerpools

Displays information on how the linker has placed veneer pools.

visibility

Lists the symbol visibility information. You can use this option with either --info=inputs or --verbose to enhance the output.

weakrefs

Lists all symbols that are the target of weak references, and whether or not they were defined.

Usage

The output from --info=sizes,totals always includes the padding values in the totals for input objects and libraries.

If you are using RW data compression (the default), or if you have specified a compressor using the --datacompressor=id option, the output from --info=sizes,totals includes an entry under Grand Totals to reflect the true size of the image.
