From 3e25c4a1e3e58bc1d00d894854a29dd2e4e7e88a Mon Sep 17 00:00:00 2001 From: Alexey Samsonov Date: Mon, 2 Jul 2012 05:54:45 +0000 Subject: This patch extends the libLLVMDebugInfo which contains a minimalistic DWARF parser: 1) DIContext is now able to return function name for a given instruction address (besides file/line info). 2) llvm-dwarfdump accepts flag --functions that prints the function name (if address is specified by --address flag). 3) test case that checks the basic functionality of llvm-dwarfdump added git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159512 91177308-0d34-0410-b5e6-96231b3b80d8 --- tools/llvm-dwarfdump/llvm-dwarfdump.cpp | 13 ++++++++++++- 1 file changed, 12 insertions(+), 1 deletion(-) (limited to 'tools/llvm-dwarfdump/llvm-dwarfdump.cpp') diff --git a/tools/llvm-dwarfdump/llvm-dwarfdump.cpp b/tools/llvm-dwarfdump/llvm-dwarfdump.cpp index ca0493de5d..b6536fa1d7 100644 --- a/tools/llvm-dwarfdump/llvm-dwarfdump.cpp +++ b/tools/llvm-dwarfdump/llvm-dwarfdump.cpp @@ -39,6 +39,11 @@ static cl::opt Address("address", cl::init(-1ULL), cl::desc("Print line information for a given address")); +static cl::opt +PrintFunctions("functions", cl::init(false), + cl::desc("Print function names as well as line information " + "for a given address")); + static void DumpInput(const StringRef &Filename) { OwningPtr Buff; @@ -92,7 +97,13 @@ static void DumpInput(const StringRef &Filename) { dictx->dump(outs()); } else { // Print line info for the specified address. - DILineInfo dli = dictx->getLineInfoForAddress(Address); + int spec_flags = DILineInfoSpecifier::FileLineInfo; + if (PrintFunctions) + spec_flags |= DILineInfoSpecifier::FunctionName; + DILineInfo dli = dictx->getLineInfoForAddress(Address, spec_flags); + if (PrintFunctions) + outs() << (dli.getFunctionName() ? dli.getFunctionName() : "") + << "\n"; outs() << (dli.getFileName() ? dli.getFileName() : "") << ':' << dli.getLine() << ':' << dli.getColumn() << '\n'; } -- cgit v1.2.3
