Bug ID: 104052
Summary: Modules ICE on powerpc64le-linux with
-mabi=ieeelongdouble
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
In gcc configured --with-long-double-format=ieee (but also just when running
make check-g++ RUNTESTFLAGS='--target_board=unix/-mabi=ieeelongdouble
modules.exp'
I'm seeing all the tests ICE like:

where the innermost type_node is called on

But I don't really see type_node called on other REAL_TYPEs, e.g. with
-mabi=ibmlongdouble
