Uli's paper pre-dates GNU2 TLS, I'm not sure whether he updated it to
cover it, so https://www.fsfla.org/~lxoliva/writeups/TLS/ might be useful.

Hello,
I have been working on link time optimization for C that may change the
size of structs (at link time). We are close to sharing the results we
have so far, but there are a couple of missing pieces left to work on:
Implementations of sizeof and offsetof that support this change in
stru

The GCC 10 branch is in regression and documentation fixing mode.
We're close to two months after the GCC 10.1 release which means
a first bugfix release is about to happen. The plan is to release
mid July and I am targeting for a release candidate mid next
week, no later than Ju

Actually, I don't see the point at all, it doesn't matter if the user
used sizeof(a) or 64 knowing that the stru

feature, I want to declare an additional variable in gcc which is reference
by our source code so that if this patch is missing, the user gets
