[U607-027] strange behaviour of orphaned output section placement when NOLOAD is used

[Johannes Kliemann]

Hi everyone,

since there hasn't been any reply in the mean time I wanted to ask if there 
are any updates on this issue?

To help clarifying the problem I added a reproducer. It consists of two units 
defining one function each. Both of these functions are to be linked into the 
.test section which is supposed to be located in the TESTRAM region as defined 
in the test.ld linker script. Calling make will build an main file and create a 
main.map mapping file. The mapping file shows that only function_1 is actually 
located in that region while function_2 is located in a .test section that has 
been automatically created in the ROM region. This behaviour only appears if 
the .test section is defined with as NOLOAD.

Best regards,
Johannes Kliemann
