--- Comment #9 from Segher Boessenkool <segher at gcc dot gnu.org> --- (In reply to Peter Bergner from comment #4) > These die because the struct we're using to check the alignment of uses long > double as the "big" aligned type. We could either disable the tests using a > "dg-require-effective-target longdouble128" or we could use a different more > aligned type in the struct.

Those have 128-bit alignment even with -mno-altivec, right? > gcc.target/powerpc/pr85657-3.c > gcc.target/powerpc/signbit-1.c > pr85657-3.c:38:20: error: unknown type name ‘__ibm128’; did you mean > ‘__int128’? > > These die because we don't create the type __ibm128 when using > -mlong-double-64, which seems strange since we do create the __float128 type > used in the test cases. > > Mike, I assume the __ibm128 type should always be created? It always should, yes. Always. Unconditionally.
