Hi!

We have the long-established SFDF for a very similar thing. So maybe
just call this SFDFTF or SDTF or something?
Alternatively
Generating arbitrary 64-bit constants on POWER can take up to 5 instructions.
However, some special constants can be generated in fewer instructions.
One special class of constants we don't handle, is constants that have one
set of consecutive 1-bits. These can be generated with a "li rT,-1"

To quickly recap, P0846 says that a name is also considered to refer to
a template if it is an unqualified-id followed by a < and name lookup
finds either one or more functions or finds nothing.
In a template, when parsing a function call that has type-dependent
arguments, we can't perform ADL rig

Hello
The ICE from the test case in PR93660 is due to the hidden caf_token and
caf_offset parameters generated by the Fortran front end due to the use of coarrays:

Amongst other things PR analyzer/96798 notes that
region_model::on_call_pre treats any builtin that hasn't been coded
yet as a no-op (albeit with an unknown return value), which is wrong
for non-pure builtins.
This patch updates that function's handling of such builtins so that it
instead conserva
Since we now have DECL_DECLARED_CONSTINIT_P, we no longer need
LOOKUP_CONSTINIT.
Bootstrapped/regtested on x86_64-pc-linux-gnu, ok for trunk?
gcc/cp/ChangeLog:
* cp-tree.h (LOOKUP_CONSTINIT): Remove.
(LOOKUP_REWRITTEN): Adjust.
* decl.c (duplicate_decls): Set DECL_DECLARE
This is a (hopefully temporary) fix to PR96791. This will make
the default be -mno-block-ops-vector-pair even on power10, so we will
not hit the issue of DSE trying to truncate a POImode register. I am
still concerned it will be possible to hit this because the MMA builtins
will also generate POImo
