Linking and linker script file

Integration with SmartNCode™ environment

•*.asmCompiler

•*.o , *.libAssembler

•*.a - executableLinker

slide 4

The Visual Linker will be a plugin to the SmartNCode Integrated Development Environment (IDE). It will provide an easy, user friendly visual linking configuration tool.

Visual Linker will ease the linker usage and reduce scripting mistakes thus minimize the time and effort one need to invest in the linking operation.

Vision

Main project challenges

LNK files parsing

COFF files parsing

Code Generation

Advanced GUI Programing using Qt framework

Two way “GUIScript” engine (optional feature).

slide 6

Lnk File parsing using LEX & YACC The Lnk file parser is needed to load

manually created /visual linker generated *.lnk files.

Parsing script elements

Translation from STL primitive elements to Qt elements

Coff files parsing Parsing Capabilities

Object Files (*.o) Libraries (*.lib)

Section Extraction

Function Extraction

Sections Merging

slide 11

Coff files parsing We will demonstrate using an example.

slide 12

Coff files parsing

slide 13

Coff files parsing After compilation 2 Object files are created:

Main.o Header.o

In the link process we will link 4 object files – the two above and two more system object,crt0.o and crtN.o

Now lets see the object files parser output.

As describes in the ARD document, we implemented the prototype: Parsed and merged sections from the coff files Parsed classes from an input *.lnk file

We experimented with Model-View-Controller

Qt implementation, Extending Views, Models and Delegates Classes.

Prototype conclusions

Lnk parsing task is feasible and taking no more than 2 milliseconds as required in the ARD document.

Object’s and libraries parsing is taking a bit longer than expected – we should check how to optimize the process.

Qt’s QUI frame work is good, it is possible to learn it using it documentation and Examples

In general – the project is massive but feasible.
