From 471f8f50d0790cd7e77b8b385d8592c95df53974 Mon Sep 17 00:00:00 2001 From: Craig Topper Date: Wed, 27 Dec 2023 23:44:45 -0800 Subject: [RISCV] Prevent checkRVVTypeSupport from issuing more than 1 diagnostic. (#74950) If vector isn't enabled at all, we might hit one of the earlier diagnostics and the requires Zve32x diagnostic. The Zve32x diagnostic would be redundant. --- clang/lib/Sema/SemaChecking.cpp | 18 +++++++++--------- 1 file changed, 9 insertions(+), 9 deletions(-) (limited to 'clang/lib/Sema/SemaChecking.cpp') diff --git a/clang/lib/Sema/SemaChecking.cpp b/clang/lib/Sema/SemaChecking.cpp index 27079ef..2e61daf 100644 --- a/clang/lib/Sema/SemaChecking.cpp +++ b/clang/lib/Sema/SemaChecking.cpp @@ -6181,22 +6181,22 @@ void Sema::checkRVVTypeSupport(QualType Ty, SourceLocation Loc, Decl *D) { if (((EltSize == 64 && Info.ElementType->isIntegerType()) || MinElts == 1) && !TI.hasFeature("zve64x")) Diag(Loc, diag::err_riscv_type_requires_extension, D) << Ty << "zve64x"; - if (Info.ElementType->isFloat16Type() && !TI.hasFeature("zvfh") && - !TI.hasFeature("zvfhmin")) + else if (Info.ElementType->isFloat16Type() && !TI.hasFeature("zvfh") && + !TI.hasFeature("zvfhmin")) Diag(Loc, diag::err_riscv_type_requires_extension, D) << Ty << "zvfh or zvfhmin"; - if (Info.ElementType->isBFloat16Type() && - !TI.hasFeature("experimental-zvfbfmin")) + else if (Info.ElementType->isBFloat16Type() && + !TI.hasFeature("experimental-zvfbfmin")) Diag(Loc, diag::err_riscv_type_requires_extension, D) << Ty << "zvfbfmin"; - if (Info.ElementType->isSpecificBuiltinType(BuiltinType::Float) && - !TI.hasFeature("zve32f")) + else if (Info.ElementType->isSpecificBuiltinType(BuiltinType::Float) && + !TI.hasFeature("zve32f")) Diag(Loc, diag::err_riscv_type_requires_extension, D) << Ty << "zve32f"; - if (Info.ElementType->isSpecificBuiltinType(BuiltinType::Double) && - !TI.hasFeature("zve64d")) + else if (Info.ElementType->isSpecificBuiltinType(BuiltinType::Double) && + !TI.hasFeature("zve64d")) Diag(Loc, diag::err_riscv_type_requires_extension, D) << Ty << "zve64d"; // Given that caller already checked isRVVType() before calling this function, // if we don't have at least zve32x supported, then we need to emit error. - if (!TI.hasFeature("zve32x")) + else if (!TI.hasFeature("zve32x")) Diag(Loc, diag::err_riscv_type_requires_extension, D) << Ty << "zve32x"; } -- cgit v1.1
