I still don't understand your answer :(. `altering' happens by running some instructions at run-time (doesn't it?), but there is nothing to run here, I'm just doing some constant declarations. The quote above clearly says that sections are all equal as the assembler is concerned (whether they will be altered or not at run-time is none of the business of gas).

I'm not sure what arch this is written for (I know Alpha and some MIPS assembly and my Intel assembly knowledge is too rusty to be of use to me), but it appears that you're declaring variables rather than constants, which makes a big difference. If they are constants, and are literally translated to their constant value at assembly time, then yes, the behaviour that you expect would be correct and gas would be wrong. However, if they are variables and are treated as such by gas, then gas is acting appropriately by saying that any variable stored in the text segment cannot be altered in such a way. > The quote above clearly says that sections are > all equal as the assembler is concerned (whether they will be > altered or not at run-time is none of the business of gas). > Thus it sounds irrelevant to my report (or I need to sleep). You're correct on the fact that gas shouldn't care (technically) since the linker is responsible for any such segment allocations. I'll look more into that...I could just be in need of sleep rather than you :-) > What huh.s does is trying to compute (at compile time) the > distance between two labels in different sections. This is > wrong, I understand that. What I don't understand is why gas > reports only one of the two errors. I believe it's because the distance computed in the second case (the error-generating case) is being stored at an address in the text segment, which gas thinks is A Bad Thing. I'll check more into this and write a few code snippets to test this on Alpha as well. I'm not closing this yet, so don't think I'm trying to get rid of you :-) I was just making a point to quote what the manual said first before preceding. I'm also trying to tackle a very ugly demangler problem on Alpha, hence the delay in really getting this resolved more immediately. C   Acknowledgement sent to "Christopher C.
