Hi!
This is an alternative approach in making STRING_CST semantics
consistent.
This means it makes STRING_CST used for literals and for initializers
use exactly the same semantics.
It makes sure that all STRING_CST have a TYPE_SIZE_UNIT, and that it is
always larger than TREE_STRING_LENGTH, the

Hi,
this is an updated version of my STRING_CSTs checking in varasm.c
patch.
It tries to answer the questions that were raised in th GO string literals
thread.
The answers are:
a) strings with TYPE_SIZE_UNIT == NULL do exist, but only for STRING_CSTs
in constructors of flexible array struct mem

Hi,
I would like to do a minor tweak to the patch.
While staring at the other patch I realized that I should
better pass size and not thissize to the check
function, instead of making use of how thissize is
computed using MIN above. This means that this condition
+ if ((unsigned)len != size &&
