Stupid GCC inline assembly CANNOT even handle local variable

[xuancong]

And also "mov (x+4),%eax" is not supported by GCC, you get a compile error.

Yes, that's pure AT&T syntax, not inline assembly.

Sure, AT&T syntax should support, but GCC inline asm doesn't support. We're talking about different things.

If you use the 'm' constraint you should be passing a specific location (calculated in your C code) - GCC will do all the offsets for you.

As an example, with a uint32_t array "t", you can use the "m" constraint with t[1]. This will let GCC do all the offset stuff (4 bytes) and save you the trouble.

So you still cannot solve the problem, right?

Not for someone with your attitude, no.

I've solved half of the problem under someone's help and have modified the initial post. Please check!

Sigh, I hate it when people do that. I get so tempted to disable editing of posts whenever I see someone do this. Congratulations, you've just thrown the entire thread out of whack. Nothing here makes sense anymore.

Well, it's not that bad actually. Since none of the replies in the entire thread solves the actual problem. Nonetheless, the issue is still there that GCC still need to be improved.

/me glances towards the mods.

Just in case you didn't get it already:

GCC inline assembly does the job it has been designed to do, and does it well.

And second:

The problem right now is that you apparently cannot wrap your mind around the concept that a "solution" does not necessarily include someone solving your problem for you, but will involve you doing some thinking on your own. Pointers have been given in plenty.
