From 83c2a98012a65b51be66fd76c3a1b13ed782c558 Mon Sep 17 00:00:00 2001 From: Anton Korobeynikov Date: Sun, 27 Dec 2009 14:27:22 +0000 Subject: [PATCH] Promote arguments of frameaddr / returnaddr builtins to i32 type, when needed. This is needed for the platforms, where bitwidth of "int" is not 32 bits (e.g. 16 on msp430). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92176 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/CGBuiltin.cpp | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) diff --git a/lib/CodeGen/CGBuiltin.cpp b/lib/CodeGen/CGBuiltin.cpp index a2328e4a49..866c58780b 100644 --- a/lib/CodeGen/CGBuiltin.cpp +++ b/lib/CodeGen/CGBuiltin.cpp @@ -340,12 +340,20 @@ RValue CodeGenFunction::EmitBuiltinExpr(const FunctionDecl *FD, return RValue::get(Address); } case Builtin::BI__builtin_return_address: { + Value *Depth = EmitScalarExpr(E->getArg(0)); + Depth = Builder.CreateIntCast(Depth, + llvm::Type::getInt32Ty(VMContext), + false, "tmp"); Value *F = CGM.getIntrinsic(Intrinsic::returnaddress, 0, 0); - return RValue::get(Builder.CreateCall(F, EmitScalarExpr(E->getArg(0)))); + return RValue::get(Builder.CreateCall(F, Depth)); } case Builtin::BI__builtin_frame_address: { + Value *Depth = EmitScalarExpr(E->getArg(0)); + Depth = Builder.CreateIntCast(Depth, + llvm::Type::getInt32Ty(VMContext), + false, "tmp"); Value *F = CGM.getIntrinsic(Intrinsic::frameaddress, 0, 0); - return RValue::get(Builder.CreateCall(F, EmitScalarExpr(E->getArg(0)))); + return RValue::get(Builder.CreateCall(F, Depth)); } case Builtin::BI__builtin_extract_return_addr: { // FIXME: There should be a target hook for this -- 2.40.0
