Panther Lake and Clearwater Forest in open-source compilers
Intel engineers laying the groundwork for the next-gen CPU series.
GCC and LLVM/Clang represent two widely adopted compilers in the C language family. GCC, short for the GNU Compiler Collection, encompasses a collection of compilers designed for various programming languages such as C, C++, Objective-C, Fortran, Ada, and Go. As one of the oldest and most prevalent open-source compilers. On the other hand, LLVM/Clang is a newer compiler project recognized for its swift and modular architecture, capable of parsing C, C++, and their derivatives.
Both GCC and LLVM/Clang operate under open-source principles, making their source code accessible to the public for contribution and customization. Intel engineers actively participate in enhancing these compilers, ensuring compatibility with forthcoming processor series like Panther Lake and Clearwater Forest.

The patches confirmed ISA (Instruction Set Architecture) for Panther Lake as following:
+Intel Panther Lake CPU with 64-bit extensions, MOVBE, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, POPCNT, AES, PREFETCHW, PCLMUL, RDRND, XSAVE, XSAVEC, XSAVES, XSAVEOPT, FSGSBASE, PTWRITE, RDPID, SGX, GFNI-SSE, CLWB, MOVDIRI, MOVDIR64B, CLDEMOTE, WAITPKG, ADCX, AVX, AVX2, BMI, BMI2, F16C, FMA, LZCNT, PCONFIG, PKU, VAES, VPCLMULQDQ, SERIALIZE, HRESET, KL, WIDEKL, AVX-VNNI, AVXIFMA, AVXVNNIINT8, AVXNECONVERT, CMPCCXADD, AVXVNNIINT16, SHA512, SM3, SM4 and PREFETCHI instruction set support.
Both CPU series are anticipated to launch in 2025. Before introducing the Panther/Clearwater series, Intel plans to unveil other CPU series, namely Arrow Lake, Lunar Lake, and Sierra Forest, all of which serve as precursors to the Panther/Clearwater lineup.
Intel has already submitted patches for Meteor, Arrow, and Lunar Lakes, with Panther Lake potentially integrating with GCC version 14, as reported by Phoronix. The GCC compilers follow an annual release schedule, indicating that after the imminent release of GCC 14, Intel will extend support for its 2025 product lineup. Conversely, AMD is expected to introduce initial patches once the new series starts shipping.
