Is there a reason that __builtin_nand32, __builtin_nand64, __builtin_nand128, __builtin_infd32, __builtin_infd64, __builtin_infd128 aren't exposed in icc, even with gcc compatibility turned on?
While it may seem pedantic, those are needed to initialise globals in C, e.g.:
static _Decimal32 foo = __builtin_infd32();
static _Decimal64 bar = __builtin_nand64("");
In gcc those are considered constant expressions. GNU libc uses a similar trick to provide NAN and INFINTIY in bits/nan.h and bits/inf.h
I know to work around this one could use
static _Decimal32 foo = (_Decimal32)__builtin_inf();
static _Decimal64 bar = (_Decimal64)__builtin_nan("");
the double equivalent, which is then cast to the target type, but this feels rather hacky.
