<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: None (Himadhith) <details> <summary>Changes</summary> Support the following packed BCD builtins for PowerPC. ``` __builtin_national2packed - Conversion of National format to Packed decimal format. __builtin_packed2national - Conversion of Packed decimal format to national format. __builtin_packed2zoned - Conversion of Packed decimal format to Zoned decimal format. __builtin_zoned2packed - Conversion of Zoned decimal format to Packed decimal format ``` ### Design decision considered: - In the documentation link`national2packed, packed2zoned and zoned2packed` use **`unsigned char`**. This is an illegal type in the LLVM backend(`llvm_i8_ty`) and it has been custom lowered in `PPC.cpp` file to fit `i8` into `i32` by zero extending it. - This was done due to the second parameter expecting the values of 0 or 1 exclusively and our front-end was unsigned char. - The 2nd argument is defined as a preferred sign field(PS) for BCD operations and is treated as an immediate operand. This is why `ImmArg<ArgIndex<1>>` was added to `IntrinsicsPowerPC.td.` ### Prototypes: `vector unsigned char __builtin_national2packed(vector unsigned char a, unsigned char b);` `vector unsigned char __builtin_packed2zoned(vector unsigned char, unsigned char);` `vector unsigned char __builtin_zoned2packed(vector unsigned char, unsigned char);` The condition for the 2nd parameter is consistent over all the 3 prototypes (0 or 1 only). `vector unsigned char __builtin_packed2national(vector unsigned char);` Reference links: - [national2packed](https://www.ibm.com/docs/en/xl-c-and-cpp-aix/16.1.0?topic=end-builtin-national2packed-clang-based-front) - [packed2national](https://www.ibm.com/docs/en/xl-c-and-cpp-aix/16.1.0?topic=end-builtin-packed2national-clang-based-front) - [packed2zoned](https://www.ibm.com/docs/en/xl-c-and-cpp-aix/16.1.0?topic=end-builtin-packed2zoned-clang-based-front) - [zoned2packed](https://www.ibm.com/docs/en/xl-c-and-cpp-aix/16.1.0?topic=end-builtin-zoned2packed-clang-based-front) --- Full diff: https://github.com/llvm/llvm-project/pull/142723.diff 10 Files Affected: - (modified) clang/include/clang/Basic/BuiltinsPPC.def (+7) - (modified) clang/lib/Basic/Targets/PPC.cpp (+6) - (modified) clang/lib/CodeGen/TargetBuiltins/PPC.cpp (+28) - (modified) clang/lib/Sema/SemaPPC.cpp (+4) - (added) clang/test/CodeGen/PowerPC/builtins-bcd-transform-negative.c (+23) - (added) clang/test/CodeGen/PowerPC/builtins-bcd-transform.c (+57) - (added) clang/test/Sema/builtins-bcd-transform.c (+30) - (modified) llvm/include/llvm/IR/IntrinsicsPowerPC.td (+8) - (modified) llvm/lib/Target/PowerPC/PPCInstrAltivec.td (+8-4) - (added) llvm/test/CodeGen/PowerPC/builtins-bcd-transform.ll (+96) ``````````diff diff --git a/clang/include/clang/Basic/BuiltinsPPC.def b/clang/include/clang/Basic/BuiltinsPPC.def index bb7d54bbb793e..0c8c7d3d1df13 100644 --- a/clang/include/clang/Basic/BuiltinsPPC.def +++ b/clang/include/clang/Basic/BuiltinsPPC.def @@ -567,6 +567,13 @@ TARGET_BUILTIN(__builtin_altivec_vextsh2w, "V4SiV8Ss", "", "power9-vector") TARGET_BUILTIN(__builtin_altivec_vextsh2d, "V2SLLiV8Ss", "", "power9-vector") TARGET_BUILTIN(__builtin_altivec_vextsw2d, "V2SLLiV4Si", "", "power9-vector") +// P9 BCD builtins (the signature used here is for informational purposes only +// as front-end emits custom codegens for these set of builtins.) +TARGET_BUILTIN(__builtin_ppc_national2packed, "V16UcV16UcUc", "t", "power9-vector") +TARGET_BUILTIN(__builtin_ppc_packed2national, "V16UcV16Uc", "", "power9-vector") +TARGET_BUILTIN(__builtin_ppc_packed2zoned, "V16UcV16UcUc", "t", "power9-vector") +TARGET_BUILTIN(__builtin_ppc_zoned2packed, "V16UcV16UcUc", "t", "power9-vector") + // P10 Vector extend sign builtins.
