µVISION: "Browse Information" option slows down building project

Information in this knowledgebase article applies to:

• Keil MDK 5
• Arm Compiler 5

SYMPTOM

I have configured my project for Arm Compiler 5.

Now, I notice that after enabling Browse Information option in Options for Target - Output in µVision, building the same project takes much longer.

Is it a known issue? How can I overcome this?

CAUSE

With Arm Compiler 5 selected, µVision will only generate Browse Information while your project is  built. This will slow down the build time of your project, especially when you rebuild your entire project. 

Enabling Browse Information may result in a 3X increase in compilation time using the ARMCC v5.x compiler.

This issue doesn't exist when Arm Compiler 6 is selected. Then, Browse Information is generated dynamically in the background as soon as you open the project. Thus, it won't cause an increase the project's build time.

RESOLUTION

Disabling the Browse Information option in Options for Target - Output in µVision will increase the project build speed.
