From fae1475823cd77fc51c75b0237a19636b36a6179 Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Fri, 12 Aug 2011 20:24:12 +0000 Subject: Initial commit of the 'landingpad' instruction. This implements the 'landingpad' instruction. It's used to indicate that a basic block is a landing pad. There are several restrictions on its use (see LangRef.html for more detail). These restrictions allow the exception handling code to gather the information it needs in a much more sane way. This patch has the definition, implementation, C interface, parsing, and bitcode support in it. llvm-svn: 137501 --- llvm/lib/Bitcode/Writer/BitcodeWriter.cpp | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) (limited to 'llvm/lib/Bitcode/Writer') diff --git a/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp b/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp index 12f0715f1a8..5b3d96953a0 100644 --- a/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp +++ b/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp @@ -1165,6 +1165,23 @@ static void WriteInstruction(const Instruction &I, unsigned InstID, break; } + case Instruction::LandingPad: { + const LandingPadInst &LP = cast(I); + Code = bitc::FUNC_CODE_INST_LANDINGPAD; + Vals.push_back(VE.getTypeID(LP.getType())); + PushValueAndType(LP.getPersonalityFn(), InstID, Vals, VE); + Vals.push_back(LP.isCleanup()); + Vals.push_back(LP.getNumClauses()); + for (unsigned I = 0, E = LP.getNumClauses(); I != E; ++I) { + if (LP.isCatch(I)) + Vals.push_back(LandingPadInst::Catch); + else + Vals.push_back(LandingPadInst::Filter); + PushValueAndType(LP.getClause(I), InstID, Vals, VE); + } + break; + } + case Instruction::Alloca: Code = bitc::FUNC_CODE_INST_ALLOCA; Vals.push_back(VE.getTypeID(I.getType())); -- cgit v1.2.3
