Last year Intel contributed Granite Rapids support for GCC 13 . Now though the newest target is Granite Rapids D as the eventual successor to Ice Lake D CPUs. Making last week's Granite Rapids D compiler patches all the more notable is that it now confirms the new AMX-COMPLEX instructions will only be found in Granite Rapids D and not Granite Rapids itself. The GCC compiler had originally positioned the AMX-COMPLEX support as premiering with Granite Rapids while now the target is being adjusted to point to the GNR-D introduction.
As of this morning the Granite Rapids D support landed in GCC Git that will be found in the GCC 14.1 stable release due out in early 2024. The compiler support enables the following extensions for Granite Rapids D:
"MOVBE, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, POPCNT, CX16, SAHF, FXSR, AVX, XSAVE, PCLMUL, FSGSBASE, RDRND, F16C, AVX2, BMI, BMI2, LZCNT, FMA, MOVBE, HLE, RDSEED, ADCX, PREFETCHW, AES, CLFLUSHOPT, XSAVEC, XSAVES, SGX, AVX512F, AVX512VL, AVX512BW, AVX512DQ, AVX512CD, PKU, AVX512VBMI, AVX512IFMA, SHA, AVX512VNNI, GFNI, VAES, AVX512VBMI2, VPCLMULQDQ, AVX512BITALG, RDPID, AVX512VPOPCNTDQ, PCONFIG, WBNOINVD, CLWB, MOVDIRI, MOVDIR64B, AVX512VP2INTERSECT, ENQCMD, CLDEMOTE, PTWRITE, WAITPKG, SERIALIZE, TSXLDTRK, UINTR, AMX-BF16, AMX-TILE, AMX-INT8, AVX-VNNI, AVX512FP16, AVX512BF16, AMX-FP16, PREFETCHI and AMX-COMPLEX instruction set support."
GCC 13 in addition to the Granite Rapids (non-D) support also already has Meteor Lake and Sierra Forest support , Emerald Rapids , and Grand Ridge . Intel continues to be very punctual in enabling new CPU support within the upstream GCC compiler well ahead of launch as well as for the LLVM/Clang compiler too.
