Here's one well known language: C23! (_Decimal32, _Decimal64, _Decimal128 [1].) Already supported by GCC [2]. Another language with support is .NET C# (System.Decimal) [3].
As for processors, according to Wikipedia [4], "IBM POWER6 and newer POWER processors include DFP in hardware, as does the IBM System z9 (and later zSeries machines). ... Fujitsu also has 64-bit Sparc processors with DFP in hardware."
