Develop and test enum #2

CristinaCristescu · 2013-07-16T08:19:44Z

So here are the changes that I needed to make from the comments of the last pull request and some other changes:

I've added the name for a enum constant because I realised when declaring kMyConstant = 42 that I didn't save the name.
I've added some checks in the TCling to see if the TEnum and TEnumConstants are actually created, because when I run the test:
// MyEnumComment
enum EMyEnum {
kMyEnumConstant = 42 // enumConstantComment
};

int assertTEnum()
{

  if (!(TEnum*)gROOT->GetListOfEnums()->FindObject("EMyEnum")) {
     Error ("TEnum", "Constructor of TEnum failure.");
     return -1;

}
It does return and Error. I tried that on the root[0] promp as well and the address of GetListOfEnum is not NULL(because the HashTable is created), but the address of FindObject is 0x0.
Now I don't get the Errors of TEnum and TEnumConstant are not created..I wanted to check whether they are added to the fEnums and fGlobals, but Add() for TCollection is a void function. My best guess is that they are not added to the lists, maybe you can see why...

…hecks.

…g. Maybe it's a bug or it is a feature.

… "toggle"

…of the load instruction. Currently, there are four kinds of instruction that may use a load instruction as its argument: load, store, GEP and call instruction. We instrument these four kinds instruction to check there may be a null pointer dereference.

This will make sure that the build is 'consistent' and the source version of the cling include files is not superseeded by the (possible stale) copy that might be in interpreter/llvm/inst.

In the value printer synthesis we have real source location of the expression that we are replacing. Use its begin and end location. This will allow us to remove the XFAIL-ed test that now passes.

With the unique_ptr, we were crash due to the held over reference described below. Trying to move the m_ExternalSemaSource deletion after the m_IncrParser deletion also leads to crash due to the double deletion (once by the ASTContext, once by m_ExternalSemaSource) of the ExternalSemaSource. If m_Callbacks is declared after m_IncrParser, it will be deleted first and if m_ExternalSemaSource is a unique_ptr, it willbe deleted before m_IncrParser is delete. During the Incremental parser deletion, there is a call to CodeGenModule::Release, then EmitTargetMetdata is called and it tries to get the most recent decl which calls clang::LazyGenerationalUpdatePtr<...>::get which has a LazyVal which has a cached pointer to the AST external source. So this placement is necessary to solve a tear down crash. #0 clang::LazyGenerationalUpdatePtr<clang::Decl const*, clang::Decl*, &(clang::ExternalASTSource::CompleteRedeclChain(clang::Decl const*))>::get (this=0x7fff5fbfe0e0, O=0x1069c3f90) at ExternalASTSource.h:428 428 (LazyVal->ExternalSource->*Update)(O); (gdb) l 423 /// Get the value of this pointer, updating its owner if necessary. 424 T get(Owner O) { 425 if (LazyData *LazyVal = Value.template dyn_cast<LazyData*>()) { 426 if (LazyVal->LastGeneration != LazyVal->ExternalSource->getGeneration()) { 427 LazyVal->LastGeneration = LazyVal->ExternalSource->getGeneration(); 428 (LazyVal->ExternalSource->*Update)(O); 429 } 430 return LazyVal->LastValue; 431 } 432 return Value.template get<T>(); #0 clang::LazyGenerationalUpdatePtr<clang::Decl const*, clang::Decl*, &(clang::ExternalASTSource::CompleteRedeclChain(clang::Decl const*))>::get (this=0x7fff5fbfe0e0, O=0x1069c3f90) at ExternalASTSource.h:428 #1 0x000000010005ce38 in clang::Redeclarable<clang::FunctionDecl>::DeclLink::getNext (this=0x1069c3ff0, D=0x1069c3f90) at Redeclarable.h:74 #2 0x000000010005cd81 in clang::Redeclarable<clang::FunctionDecl>::getNextRedeclaration (this=0x1069c3ff0) at Redeclarable.h:119 #3 0x000000010005d0b3 in clang::Redeclarable<clang::FunctionDecl>::getMostRecentDecl (this=0x1069c3ff0) at Redeclarable.h:161 #4 0x000000010137bfdc in clang::FunctionDecl::getMostRecentDeclImpl (this=0x1069c3f90) at Decl.h:1568 #5 0x00000001004b5346 in clang::Decl::getMostRecentDecl (this=0x1069c3f90) at DeclBase.h:806 #6 0x0000000100897128 in clang::CodeGen::CodeGenModule::EmitTargetMetadata (this=0x10689aa00) at /Users/pcanal/root_working/code/rootcling/interpreter/llvm/src/tools/clang/lib/CodeGen/CodeGenModule.cpp:3271 #7 0x0000000100895237 in clang::CodeGen::CodeGenModule::Release (this=0x10689aa00) at /Users/pcanal/root_working/code/rootcling/interpreter/llvm/src/tools/clang/lib/CodeGen/CodeGenModule.cpp:395 #8 0x0000000100981b3c in clang::CodeGeneratorImpl::ReleaseModule (this=0x106506d70) at /Users/pcanal/root_working/code/rootcling/interpreter/llvm/src/tools/clang/lib/CodeGen/ModuleBuilder.cpp:82 #9 0x00000001001c3f88 in ~IncrementalParser (this=0x1065047e0) at /Users/pcanal/root_working/code/rootcling/interpreter/cling/lib/Interpreter/IncrementalParser.cpp:168 #10 0x00000001001c3f25 in ~IncrementalParser (this=0x1065047e0) at /Users/pcanal/root_working/code/rootcling/interpreter/cling/lib/Interpreter/IncrementalParser.cpp:166 #11 0x00000001001d8905 in std::__1::default_delete<cling::IncrementalParser>::operator() () at /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/c++/v1/memory:2426 #12 0x00000001001d8905 in ~unique_ptr [inlined] () at /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/c++/v1/memory:2625 #13 0x00000001001d8905 in ~Interpreter (this=0x7fff5fbff020) at memory:2593 #14 0x00000001001d8355 in ~Interpreter (this=0x7fff5fbff020) at /Users/pcanal/root_working/code/rootcling/interpreter/cling/lib/Interpreter/Interpreter.cpp:229 #15 0x00000001002b0318 in main (argc=1, argv=0x7fff5fbff740) at /Users/pcanal/root_working/code/rootcling/interpreter/cling/tools/driver/cling.cpp:97

ROOT needs reflection information about classes. One way to incorporate this information is to use a ClassDef macro, which adds a few members to the classes. For example, how to read/write the class on disk (aka streamer). The ClassDef adds forward declaration of a streamer function (and a few others) in the body of the class. Later on a special tool (aka rootcling) defines the forward declarations unless told otherwise by the dictionary generation driver (aka Linkdef file). Simply explained, the ROOT IO-aware class *declare* a few functions, whoose definitions will come from a dictionary. As always the interesting part comes when C++ templates come around. Depending on the order of the header files, which appear in the dictionaries the template class can be instantiated. For example: A.h: template<class T> struct TMyClassT { ...; ClassDef(MyClassT, 1); }; B.h: struct S { TMyClassT<int> var; }; G__: #include "A.h" // #1 #include "B.h" // #2 // Definitions of the contents of the ClassDef. B.h forces an implicit instantiation of TMyClassT *before* the compiler can see the definitions of the ClassDef. Namely, template <> TClass *TMyClassT<int>::Class(){} is seen after #2 when the compiler has instantiated it. C++ 14.7.3/6 explains it as: "If a template, a member template or a member of a class template is explicitly specialized then that specialization shall be declared before the first use of that specialization that would cause an implicit instantiation to take place, in every translation unit in which such a use occurs; no diagnostic is required." Saying that what we do makes the TU ill-formed but no diagnostic is required. Modules are more strict in that respect and issue diagnostics. This commit introduces a workaround while the actual solution to the problem is being developed. As Axel and I discussed a real solution would be to implement a ClassDef macro which inlines the contents, disallowing custom streamers covering 99.9% of the cases.

In the logging for out-of-range values in `RooTreeDataStore::loadValues`, there was `static_cast<RooAbsReal*>(arg)->getVal()` called also for categories, which is invalid. This led to garbage numbers as here in the tutorial outputs: https://root.cern/doc/v624/rf401__importttreethx_8C.html (see the lines with `Skipping event #2 because i cannot accommodate the value`)

In the jitted version of the `Vary` transformation a node is allocated on the heap and its address is passed down to the function `JitVariationHelper`, which is also responsible for deleting the allocated memory. In case a mismatch in the return type of the jitted function given to the Vary call is detected, we throw an error to inform the user they should return an RVec for the Vary to properly work. This means that the call to JitVariationHelper does not happen, thus the memory of the node is not deallocated. This commit corrects that behaviour by properly deleting the pointer before throwing the exception.

In the jitted version of the `Vary` transformation a node is allocated on the heap and its address is passed down to the function `JitVariationHelper`, which is also responsible for deleting the allocated memory. In case a mismatch in the return type of the jitted function given to the Vary call is detected, we throw an error to inform the user they should return an RVec for the Vary to properly work. This means that the call to JitVariationHelper does not happen, thus the memory of the node is not deallocated. This commit corrects that behaviour by properly deleting the pointer before throwing the exception.

In CLINGCXXFLAGS, put the source include dir first.

24a1203

This will make sure that the build is 'consistent' and the source version of the cling include files is not superseeded by the (possible stale) copy that might be in interpreter/llvm/inst.

Not using real SourceLocation is bad, especially in -verify mode.

4326f21

In the value printer synthesis we have real source location of the expression that we are replacing. Use its begin and end location. This will allow us to remove the XFAIL-ed test that now passes.
