From 063989455d9ce10e61e2c617394d403218b3ec03 Mon Sep 17 00:00:00 2001 From: Dale Johannesen Date: Thu, 18 Jun 2009 01:07:23 +0000 Subject: It looks like nobody is working on PR 4158, so I'm adding a check to catch this case at compile time instead of quietly generating incorrect code. That will at least let us identify CBE failures that are not due to this problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73668 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/CBackend/CBackend.cpp | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/lib/Target/CBackend/CBackend.cpp b/lib/Target/CBackend/CBackend.cpp index 7b5ab6e..c3554f6 100644 --- a/lib/Target/CBackend/CBackend.cpp +++ b/lib/Target/CBackend/CBackend.cpp @@ -1454,6 +1454,17 @@ std::string CWriter::GetValueName(const Value *Operand) { /// writeInstComputationInline - Emit the computation for the specified /// instruction inline, with no destination provided. void CWriter::writeInstComputationInline(Instruction &I) { + // We can't currently support integer types other than 1, 8, 16, 32, 64. + // Validate this. + const Type *Ty = I.getType(); + if (Ty->isInteger() && (Ty!=Type::Int1Ty && Ty!=Type::Int8Ty && + Ty!=Type::Int16Ty && Ty!=Type::Int32Ty && Ty!=Type::Int64Ty)) { + cerr << "The C backend does not currently support integer " + << "types of widths other than 1, 8, 16, 32, 64.\n"; + cerr << "This is being tracked as PR 4158.\n"; + abort(); + } + // If this is a non-trivial bool computation, make sure to truncate down to // a 1 bit value.
