Bug ID: 70179
Summary: PPC64 ICE with -mabi=ieeelongdouble and long double
complex
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: koorogi+bugs at koorogi dot info
Target Milestone: ---
GCC has an internal compiler error with trivial code using long double complex
values on powerpc64 using -mlong-double-128 and -mabi=ieeelongdouble.
~> cat ldcomplex.c
long double _Complex foo();
long double _Complex bar() { return foo(); }
~> ppc-gcc -mlong-double-128 -mabi=ieeelongdouble -c ldcomplex.c -o ldcomplex.o
ppc-gcc: warning: using IEEE extended precision long double
cc1: warning: using IEEE extended precision long double
ldcomplex.c: In function 'bar':
ldcomplex.c:2:37: internal compiler error: in read_complex_part, at expr.c:3072

See <http://gcc.gnu.org/bugs.html> for instructions.
This was with the gcc 6 snapshot from 20160228. Earlier versons of the
compiler that I've tested (5.2.0 and 4.9.2) have a segmentation fault on the
same test case.
