Brackets Appear Red in Generated Assembly File (.asm)

[DS-567]

Hi everyone,

I have been writing various C programs for NEORV32 and comparing it the compiled and assembled binaries shown in the main.asm file. But I have came across in various places where some of the brackets (both curly and normal) appear red and others do not. This may be a general assembly question more so than a RISC-V question, but figured I would ask it here because I am using NEORV32.

I noticed this because I had a few functions that were called from main(), but as part of an experiment I added the function code body inside main() so there was no function call to executer the same logic. When I looked at the assembly it appeared like this:

The code compiled fine but maybe this is an optimization by the compiler to remove the code. I checked the demo_blink_led assembled asm file and there appears a red bracket here too (see below).

Is there a specific reason they appear red? Or could it be to do with not having the correct RISC-V extensions enabled?

I have just checked an assembly file generated by the NEORV32 software framework and there is no "formatting" data encoded within the file - only raw ASCII (UTF-8) stuff. So maybe this is just the syntax highlighting of your editor? 😅

Ah, you are correct. I opened using a different editor and the parentheses are no longer strange. Must be a syntax issue with VSC 🤨. Thanks Stephan.
