Re: [U-Boot] [PATCH 3/3 v2] Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value

Dear Alessandro Rubini,

In message 20101026214042.GA2897@morgana.i.gnudd.com you wrote:

I am not convinced, as we don't have an array context here.

But sizeof(struct x) doesn't depend on how struct x is used. You can declare a pointer and then allocate for an array.

I don't see that with

struct foo x; struct foo y[N];

we have a guarantee that sizeof(x) == sizeof(y[0]).

Yes, I see this requirement. But maybe we're already bikeshedding: I won't get offended if you keep the global +15 & ~15.

Please let me get -rc1 out, and all the urgent problems fixed first. I will try to keep this in mind and re-check when there is a little more time. Thanks!

Best regards,

Wolfgang Denk
