[PATCH] D100032: [X86][AMX] Add description of x86_amx to LangRef.

[LuoYuanke via Phabricator via llvm-commits]

LuoYuanke added inline comments.


================
Comment at: llvm/docs/LangRef.rst:3149
+The x86_amx type represents a value held in an AMX tile register on an x86
+machine. The operations allowed on it are quite limited: stride load and store,
+zero, dot product. User-specified AMX instructions are represented as intrinsic.
