Fix ldbl-128 / ldbl-128ibm erfcl for -Wuninitialized
The ldbl-128 and ldbl-128ibm implementations of erfcl produce uninitialized variable warnings with -Wuninitialized because of switch statements where in fact one of the cases will always be executed, but the compiler does not see that these cases cover all possibilities (and because the reasoning that it does involves inequalities on the representation of a floating point value leading to a set of possible values for 8.0 times that value, converted to int, it's highly nontrivial for the compiler to see that). This patch fixes those warnings by converting the last case in those switch statements to a "default" case. Tested for powerpc and mips64. * sysdeps/ieee754/ldbl-128/s_erfl.c (__erfcl): Make case 9 in switch statement into default case. * sysdeps/ieee754/ldbl-128ibm/s_erfl.c (__erfcl): Likewise.
