XMCStaticStackAnalyzer

Static stack analyser for Infineon XMC4 µControllers based on assembler list file

---

Abstract

This program parses a compiler list file and calculates the estimated stack usage of it. It is build for assembler list files generated by ARM gcc in general and XMC4-µControllers from Infineon in special with Cortex M4 architecture. May be also functional for Infineon XMC1 / Cortex M0 (not extensively tested).

How to use

This is a GUI program; so

• simply start it

• select

  • Display mode:
    • Markdown table
    • call tree
  • in the latter case (call tree):
    select max. call deepth shown
  • include functions (excluded by default):
    • with no stack usage
    • system calls (function beginning with an underscore "_")

  Note that this only affects the display, not the calculation of stack usage!

• select display sort order:

  • alphabetic
  • by own stack usage
  • by deepest stack usage

• load an assembler list file (*.lst) file via button

• if display mode is "Markdown table":
  save it as markdown table via save button

Program output

The output consits of following columns:

• Friendly Name: function name in a friendly spelling
  Compiler decorates function names in various ways; these decorations are deleted here to

  • make names more readable
  • have a better relation to C-Source-Code

  See column "Name" for original (decorated) name.

• Own: the function's stack usage

• Deepest: Deepest estimated stack usage

• CallDeepth: Deepth of call tree

• CallCnt: number of functions calling thes functions

• Flags to indicate some situations the stack usage couldn't calculated:

  • 'P': function uses pointers to call other functions
  • 'I': called functions are using indirect function calls, too
  • 'V': stack is manipulated by variable's values
  • 'R': function is called (directly or indirectly) recursively by itself

• Name: Original name from assembler listing

Build the program

This program is written in Delphi using Embarcadero Rad Studio 10.3.3 / Common edition.

To build the application simply load the project file into the IDE and compile the configuration as you need (Win32/64, Debug/Build). An additional configuration "Doxygen" is also available to build the documentation using DelphDox-ALIASES. This was tested with Doxygen V.1.9.1 but should run with older versions, too.
