  "message": "rs6000: Add the __dmr1024 opaque type.\n\nThe changes have been bootstrapped and regression tested on\npowerpc64le-linux.\n\nRegister __dmr1024 as a new 1024-bit opaque built-in type, following\nthe same pattern as the existing __vector_pair (OOmode) and\n__vector_quad (XOmode) opaque types.  __dmr1024 uses TDOmode, which\nwas already added in a previous commit (\"rs6000: Add TDOmode\nsupport\"), and is intended to hold the contents of a Dense Math\nRegister (DMR) when the Dense Math Facility (-mdense-math) is\nenabled.\n\n2026-07-22  Manjunath Matti  \u003cmmatti@linux.ibm.com\u003e\n\ngcc/\n\t* config/rs6000/rs6000.h (RS6000_BTI_dmr1024): New enumerator.\n\t(RS6000_BTI_ptr_dmr1024): New enumerator.\n\t(dmr1024_type_node): New macro.\n\t(ptr_dmr1024_type_node): New macro.\n\t* config/rs6000/rs6000-builtin.cc (rs6000_type_string): Handle\n\tdmr1024_type_node.\n\t(rs6000_init_builtins): Register the __dmr1024 opaque type and\n\tits pointer-to-const variant, with 512-bit alignment.\n\t* config/rs6000/rs6000.cc (rs6000_mangle_type): Handle\n\tdmr1024_type_node.\n\t(rs6000_invalid_conversion): Reject conversions to/from TDOmode.\n\t(rs6000_opaque_type_invalid_use_p): Gate __vector_quad and\n\t__vector_pair on TARGET_MMA and __dmr1024 on TARGET_DMF\n\tindependently, and require -mdense-math for __dmr1024.\n\ngcc/testsuite/\n\t* gcc.target/powerpc/dmr1024-alignment.c: New test case.\n\t* gcc.target/powerpc/dmr1024-compile.c: Likewise.\n\t* gcc.target/powerpc/dmr1024-invalid-use-1.c: Likewise.\n\t* gcc.target/powerpc/dmr1024-invalid-use-2.c: Likewise.\n\t* gcc.target/powerpc/dmf-no-mma.c: Likewise.\n",
