when updating cum-words.

If we want to be ABI compatible, I'm afraid it needs to be 16 byte aligned
only.
We don't align aligned(64) structs to 64 bytes either, even with -mavx.

That is going to break the ABI a lot. You'd e.g. change long double passing
for -m64.
What you IMHO want is to do what the code currently does, and if the alignment
after that is 32 bytes, use a predicate similar

The symbols are weak undefs because libgfortran doesn't require (and shouldn't

Not sure whether the testcase is valid or not. The multiplication using char

but (char) 3024 is -48. For int that would be clear undefined

I guess best would be to wait for the constexpr work, then use that as an
infrastructure to discover ctors that aren't marked as constexpr, but they
could be and use that at bit together with !TREE_USED during

Seems the problem here is extremely long loc_chain lists (the longest one in
insert_into_intersection has 3740 entries), so e.g. insert_into_intersection is
extremely time consuming. Most of the locations in the long

That part comes from the questionable testcase, which does
a_sp = matrix%local_data_sp
before the loop unconditionally, eventhough matrix%local_data_sp is
uninitialized unless use_sp is .true.
Without the unswitching
--- Comment #19 from jakub at gcc dot gnu dot org 2010-06-25 09:19 ---
The compiler doesn't know that matrix%local_data_sp is uninitialized (at least
unless it would propagate that info in some IPA pass), matrix%local_data_sp is
a field in what an arguments points at (and the argument

True. Most of the fields of the pointer are still uninitialized (NULLIFY only
clears the data field).
I'm afraid when NULLIFY doesn't clear the whole struct there will be always a
possibility valgrind might complain

This goes wrong with -O2 -funroll-loops already during tree opts. In vrp2 we
have:
b[2][1]{lb: 1 sz: 1} = D.1599_148;
b[3][1]{lb: 1 sz: 1} = D.1599_154;
D.1635_152 = 2;
D.1636_151 = b[2][1]{lb: 1 sz: 1};
