Ok, the three options in Lazarus IDE for Intel CPUs are "Default",
"Intel" and "AT&T"
It is a little misleading but still correct.
Other CPUs only have the default and no selection is needed. Is this correct?
It means the GUI is good now. It hides the assembler settings for
non-Intel CPUs.
Yes, I agree. :)

The parser is another thing. Its idea was to be as "dummy" as possible, not analyzing the meaning of options but only make a GUI for them. However the FPC help output is so ambiguous that the parser must guess and hard-wire many things. Hopefully we can make the output more precise in future. Dmitry Boyarintsev is working on JSON based configuration. It would be precise and easier to parse. We may offer it for FPC project as a patch sometime in future.

Correction: actually the options are read with user defined TargetOS and TargetCPU as parameters for FPC, like : ParsedTarget := '-T$(TargetOS) -P$(TargetCPU)'; GlobalMacroList.SubstituteStr(ParsedTarget); Lines:=RunTool(fCompilerExecutable, ParsedTarget + ' -i'); But it works only if the compiler supports them.

"-h" output at "-R" says here: -R Assembler reading style: -Rdefault Use default assembler for target Well, I would be happy if somebody provides a patch for the remaining lists. The code is structured so that it is easy to add processor type lists. See TCompilerConfigTargetFrame.UpdateByTargetCPU This issue is now low priority for me because of 3 reasons: 1. In a way it is fixed now as wrong values cannot be selected any more. Now this issue is something between a bug and a feature. 2. This development is parallel to the "All Options" parser and GUI that I made earlier. It reads options directly from FPC, but only for the current platform / CPU. How these two things could be combined? I don't know and I don't think about it now. Later maybe... 3. I want to get some bugs fixed for the coming Lazarus 1.2 branch. They get higher priority. Next week I start new work at a place far away from my home. I stay there for 2 weeks and then continue by tele-cummuting. I keep my thumbs up for myself that it will work out. In any case my resources for this project will be limited then.

It is this section: Supported CPU instruction sets: My version shows only "ATHLON64" which I fixed now in the code for x86_64 CPU. Mattias earlier told me about "fpc -P" option for selecting the CPU, but it would require a cross-compiled fpc or something. For me only this works: $ fpc -i -Px86_64 Other values like "fpc -i -Pi386" or "fpc -i -Parm" give an error: Error: ppc386 can't be executed, error message: Failed to execute "ppc386", error code: 127 One thing is that selecting a different CPU family and processor type in Lazarus IDE is not supported by FPC in most cases, but at least we should see realistic choices in the list.

I don't know which processor types are available for each CPU family. I would need help filling the selection lists.
