E.g., without this flag, the conditions of patterns @extenddf2 and extendsf2 do not hold, and so GCC resorts to libcalls instead of even trying rs6000_expand_float128_convert. Perhaps the conditions are too strict, and they could enable the use of conversion insns involving __ieee128/_Float128 even with 64-bit long doubles. Alas, for now, we need this flag for the test to pass on target variants that use 64-bit long doubles. for gcc/testsuite/ChangeLog * gcc.target/powerpr/pr79004.c: Add -mlong-double-128.
