* [ABI] Fix SystemV ABI to handle nested aggregate type returned in registerAlex Langford2019-06-041-1/+2

* Inject only relevant local variables in the expression evaluation contextRaphael Isemann2019-05-021-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: In r259902, LLDB started injecting all the locals in every expression evaluation. This fixed a bunch of issues, but also caused others, mostly performance regressions on some codebases. The regressions were bad enough that we added a setting in r274783 to control the behavior and we have been shipping with the setting off to avoid the perf regressions. This patch changes the logic injecting the local variables to only inject the ones present in the expression typed by the user. The approach is fairly simple and just scans the typed expression for every local name. Hopefully this gives us the best of both world as it just realizes the types of the variables really used by the expression. Landing this requires the 2 other issues I pointed out today to be addressed but I wanted to gather comments right away. Original patch by Frédéric Riss!

* Fix infinite recursion when calling C++ template functionsFrederic Riss2019-04-243-0/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: When we encounter a templated function in the debug information, we were creating an AST that looked like this: FunctionTemplateDecl 0x12980ab90 <<invalid sloc>> <invalid sloc> foo<int> |-TemplateTypeParmDecl 0x12980aad0 <<invalid sloc>> <invalid sloc> class depth 0 index 0 T |-FunctionDecl 0x12980aa30 <<invalid sloc>> <invalid sloc> foo<int> 'int (int)' extern | |-TemplateArgument type 'int' | `-ParmVarDecl 0x12980a998 <<invalid sloc>> <invalid sloc> t1 'int' `-FunctionDecl 0x12980aa30 <<invalid sloc>> <invalid sloc> foo<int> 'int (int)' extern |-TemplateArgument type 'int' `-ParmVarDecl 0x12980a998 <<invalid sloc>> <invalid sloc> t1 'int' Note that the FunctionTemplateDecl has 2 children which are identical (as in have the same address). This is not what Clang is doing: FunctionTemplateDecl 0x7f89d206c6f8 </tmp/template.cpp:1:1, line:4:1> line:2:5 foo |-TemplateTypeParmDecl 0x7f89d206c4a8 <line:1:10, col:19> col:19 referenced typename depth 0 index 0 T |-FunctionDecl 0x7f89d206c660 <line:2:1, line:4:1> line:2:5 foo 'int (T)' | `-ParmVarDecl 0x7f89d206c570 <col:9, col:11> col:11 t1 'T' `-FunctionDecl 0x7f89d206cb60 <line:2:1, line:4:1> line:2:5 used foo 'int (int)' |-TemplateArgument type 'int' `-ParmVarDecl 0x7f89d206ca68 <col:9, col:11> col:11 t1 'int':'int' The 2 chidlren are different and actually repesent different things: the first one is the unspecialized version and the second one is specialized. (Just looking at the names shows another major difference which is that we create the parent with a name of "foo<int>" when it should be just "foo".) The fact that we have those 2 identical children confuses the ClangImporter and generates an infinite recursion (reported in https://llvm.org/pr41473). We cannot create the unspecialized version as the debug information doesn't contain a mapping from the template parameters to their use in the prototype. This patch just creates 2 different FunctionDecls for those 2 children of the FunctionTemplateDecl. This avoids the infinite recursion and allows us to call functions. As the XFAILs in the added test show, we've still got issues in our handling of templates. I believe they are mostly centered on the fact that we create do not register "foo" as a template, but "foo<int>". This is a bigger change that will need changes to the debug information generation. I believe this change makes sense on its own.

We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

* Android.rules: Use libc++ by defaultPavel Labath2018-06-221-0/+5
| | | | | | | | | | | | | | | | libstdc++ will soon be dropped from the android NDK. This patch makes sure we are prepared for that by using libc++ in tests by default (i.e., except for libstdc++ data formatter tests). Only a couple of small tweaks were needed to make this work: - Add the libc++ include paths to CXXFLAGS only. This was necessary to make the tests compile with -fmodules. The modules tests have been disabled, but this way, they will be ready for them if they are enabled. - in one test I had to add an explicit std::string copy to make sure the copy constructor is there for the expression evaluator to find it. llvm-svn: 335344
* Make test sources compatible with android+libcxx+modulesPavel Labath2018-06-206-54/+53
| | | | | | | | | | | | | | In a modules build, android is very picky about which symbols are visible after including libc++ headers (e.g. <cstdio> defines only std::printf and not ::printf). This consolidates the tests where this was an issue to always include the <c???> version of the headers and prefixes the symbols with std:: as necessary. Apart from that, there is no functional change in the tests. llvm-svn: 335149

* Really test type lookup in TestCppTypeLookup.pyFrederic Riss2018-05-081-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: ... and fix one bug found this way. Currently, the test works not because types are looked up correctly, but because by injecting local variables we also materialize the types for Clang. If we disable the local variable injection, then one check fails. The reason of the failure is that FindTypes is run with max_matches==1 and this value is passed down to the symbol lookup functions. When the search is performed only on the basename (like it's the case for an entity defined in the root namespace), then the search will stop after having found one match on the basename. But that match might be in a namespace, we were really just looking up the basename in the accelerator tables. The solution is to not pass max_matches down, but to search without a limit and let RemoveMismatchedTypes do its job afterwards. Note the patch includes 2 hunks with the same change, but only the latter is tested. I couldn't find a way to create a testcase for the other branch of the if ('image lookup -t' allows me to get there, but it only ever returns one type anyway).
