When cling is embedded and the plugins are linked statically we can rely
on the initialization of the Preprocessor to register the pragmas.
Currently, due to the current implementation deficiency we cannot rely
on the same mechanism when loading the plugins as shared objects.
This patch fixes the failing cling test.
The new release includes some improvements in both Forward and
Reverse mode:
* Support `x += y`, `x -= y`, `x *= y`, `x /= y`, `x++`, `x--`, `++x`, `--x`
in forward mode.
* Reduce emission of unused expressions
* Add a special `#pragma clad ON/OFF/DEFAULT` to annotate regions which
contain derivatives
* Various small optimizations

This reverts commit 0f583c7ef0173fba1caa7680188e7bc767f5d97d.
We need this change because whoever uses MetaParser.h will not be
able to compile their program. MetaParser.h includes MetaLexer.h.
This feature can be enabled by setting an env variable ROOT_CLING_TIMING.
It prints some information about how much time different parts of clang
take.
We use the target clingInterpreter in a few places as a
general dependency rule making sure the cling infrastructure is
already built.
In some cases, such as clad, the highly parallel builds trigger
build of clad before clangSema, clangBasic and clangAST are built.
This patch ensures the right dependencies are in order.
static, static inline, always_inline, and extern inline functions can
always be deferred. Normal inline functions can be deferred in C99/C++.
Implicit template instantiations can also be deferred in C++.
This patch changes the linkage of the declarations from strong to weak.
It allows clang to defer the deserialization from pch/pcm until their use.
This fixes https://sft.its.cern.ch/jira/browse/ROOT-9672 by having
cling::Interpreter::DeclareCFunction return the transaction containing the
compiled code.
With the previous code, cling::Interpreter::compileFunction will get confused by
transaction created during the callbacks executed during the
cling::IncrementalParser::commitTransaction of the main transaction.
Reproducer:
With a main composed of 'only':
int main(int argc, char ** argv)
{
char const * class_string = (argc == 2) ? argv[1] : "std::vector<int>";
auto const result [[gnu::unused]] = TClass::GetClass(class_string);
return 0;
}
which is a representation of real use case (in a more complex setup) in ART.
We were getting:
Error in <TClingCallFunc::make_wrapper>: Failed to compile

Error in <TClingCallFunc::ExecT>: Called with no wrapper, not implemented!

The reason is that during TClingCallFunc::make_wrapper, the call to cling::Interpreter::compileFunction ends with:
if (const llvm::GlobalValue* GV
= getLastTransaction()->getModule()->getNamedValue(name))
However in the 'broken' case, the getLastTransaction does not return the transaction for the code being compiled by DeclareCFunction but instead the one used/created at:

This is the final version of "printValue" discussion.
We agreed that printValue interface should be altered to ToString
interface, which can be invoked `gInterpreter->ToString(XYZ)`. (ToString is in TCling and toString is in Interpreter :D)
This patch contains:
- Implementation of toString in Interpreter.cpp
- Re-Implementation of ClingPrintValue to use ToString because I changed to use Evaluate some time ago.
- Removing of RVec version of printValue which wasn't used at all
- Fix test/vecops_rvec.cxx, printValue is never supposed to be called by a normal user.
Calling VirtualQuery() is very expansive. For example, the testUnfold5a.C tutorial (interpreted) times out after 3600 seconds, and runs in about 60 seconds without calling VirtualQuery(). So just bypass it and return true for the time being
The new release includes some improvements in both Forward and
Reverse mode:
* Better correctness of C++ constructs -- handle scopes properly; allow proper
variable shadowing; and preserve namespaces.
* Efficient evaluation in forward mode.
* Reduced cloning complexity.
* Handle more C++ constructs -- variable reassignments and for loops.

Visual Studio 2017 doesn't use the registry anymore, so no need to try to find keys. This prevent picking wrong directories in the case there is another version installed on the computer, and prevent also the following errors when starting ROOT:
RegQueryValueEx: returned 2: The system cannot find the file specified.
RegOpenKeyEx: returned 2: The system cannot find the file specified.
* Revert "[cmake] Narrow the list of included directories."
This reverts commit 88c16588108508eff66cc160d244c4a59eb157ed.
* Revert "[cxxmodules] Build cling runtime into module."
This reverts commit 76a9ce75d2c29c169812b0816163ac7ce27ffad5.
This patch splits the headers required at both compile time and runtime.
The Cling_Runtime_Extra module does not require __CLING__ to be defined.
It allows the headers from it to be included at compile time as well
where we do not have __CLING__ defined.
