2020-09-30bridges: add a Windows Arm64 UNO bridgeJan-Marek Glogowski
Since Microsoft follows the general ARM64 ABI calling conventions, and the SEH exception handling is the same, this result is a mixed port of the gcc3_linux_aarch64 bridge and the refactored x86-64 exception handling. I have no idea, if the complicated 32-bit handling in RaiseInfo() is needed, as the ARM64 trampolines definitly use 64-bit code. But since this is the first working version, I currently don't mind much ;-) There is definitly more potential for refactoring in the whole bridges directory...

2020-09-17WIN bridges: unify exception handlingJan-Marek Glogowski
This is almost just refactoring, but with classes like type_info_ and __type_info, just following the code became tendious. I tried to come up with better names... and in the end included some minor code changes described below. This patch moves the "common" code for MSVC exception handling into msvc_shared/except.cxx. Still it contains a few small ifdefs, so it doesn't feel like clean separation, but a lot of duplicate code is dropped this way. The "major" code change for amd64 is the drop of the duplicate static RTTInfo object originally used by mscx_getRTTI and mscx_getRTTI_len, by merging of both functions into the single, new get() function to use a single std::find call.

2020-09-17WIN bridges: unify bridge code layoutJan-Marek Glogowski
This just a cosmetic change to minimize the diff between the files of the different msvc bridges, by renaming variables, adapting comments and reordering variables. This includes the reduction of the "using namespace" to com::sun::star, so a few types now gain an uno:: prefix.

2020-08-21Pass -fno-lto unconditionallyStephan Bergmann
At least when building the libreoffice rpm on Fedora 33, the relevant -flto... flags are passed in via the global CFLAGS/CXXFLAGS, and no --enable-lto configure option is given. That caused this library to be built with LTO there, which in turn caused at least aarch64 to fail the %check step with > ### unexpected exception content! failed > ### unexpected exception content! failed > ### unexpected exception content! failed > exception test failed > oneway exception test failed > exception occurred: error: test failed! testtools/source/bridgetest/bridgetest.cxx:1176 > > > error: error: test failed! testtools/source/bridgetest/bridgetest.cxx:1176 > > dying...make[1]: *** [testtools/CustomTarget_uno_test.mk:25: workdir/CustomTarget/testtools/uno_test.done] Error 1 > make: *** [Makefile:166: CustomTarget_testtools/uno_test] Error 2 The easiest fix appears to pass -fno-lto unconditionally: For one, both GCC and Clang appear to support it since before our baseline versions (GCC: baseline 7.0.0, presumably supported since <https://gcc.gnu.org/git/?p=gcc.git;a=commit; h=d7f09764d7bc66b9997c811c22e11efc87b44792> "Merge lto branch into trunk" in releases/gcc-4.5; Clang: baseline 5.0.2 (at least on Linux), presumably supported since <https://github.com/llvm/llvm-project/commit/ 10d0868efb320fc33ced13b0abeea7070cd41635> "Driver: Support -fno-lto" in releases/3.0.x). For another, the other (few) places in the code that check ENABLE_LTO appear not to be relevant at least for that Fedora 33 rpm build, so there appears to be no incentive to make that build configure --enable-lto as an alternative to this fix.

2020-08-13gcc3_linux_{aarch64,x86-64} need the __cxa_exception hack in deleteExceptionStephan Bergmann
* gcc3_linux_aarch64 needs a hack to detect the reserve member in LLVM >= 10 libcxxabi __cxa_exception, in addition to the existing hack for LLVM 5. On macOS arm64 (which shares the bridges/source/cpp_uno/gcc3_linux_aarch64/ code) we know that we always target a >= LLVM 10 libcxxabi, so we do not need neither of the two hacks there. (And a7d1fed24557b203acb5016a98af26f4ef24d27a "Hack to dynamically adapt to __cxa_exceptiom in LLVM 5.0 libcxxabi" had introduced a "fillUnoException" vs. "mapException" typo in the comment when it copied it from bridges/source/cpp_uno/gcc3_macosx_x86-64/except.cxx.) * Similarly, gcc3_linux_x86_64 needs both hacks when it is built against libcxxabi (and the need for the LLVM 5 hack had gone unnoticed there for now). * It is not clear to me now why gcc3_macosx_x86-64 needs the LLVM 5 hack (which I even initially developed for that platform, 7a9dd3d482deeeb3ed1d50074e56adbd3f928296 "Hack to dynamically adapt to __cxa_exceptiom in LLVM 5.0 libcxxabi") but not the LLVM >= 10 hack (although it does need the corresponding hack in fillUnoException when running against recent upstream LLVM trunk libcxxabi, f4b6f6a8ae60bdec53512728d00853b73fa18500 "Hack to dynamically adapt to __cxa_exceptiom in LLVM 11 libcxxabi".

2020-08-10Make the C++/UNO bridge work to some extent on macOS on arm64Tor Lillqvist
Use the same code as for Linux on aarch64, with minor additional hacks. But that will not actually work in all cases, as there are slight differences in the ABI. See https://developer.apple.com/library/archive/documentation/Xcode/Conceptual/iPhoneOSABIReference/Articles/ARM64FunctionCallingConventions.html Thus we can drop the use of the lo_mobile_throwException() hack that was very temporarily used. The run-time code generation requires use of a new API on macOS to work: See the use of pthread_jit_write_protect_np() in bridges/source/cpp_uno/shared/vtablefactory.cxx. For some reason, with the Xcode 12 betas, when compiling for arm64-apple-macos, the symbols for the type_infos for the UNO exception types (_ZTIN3com3sun4star3uno16RuntimeExceptionE etc) end up as "weak private external" in the object file, as displayed by "nm -f darwin". We try to look them up with dlsym(), but that then fails. So use a gross hack: Introduce separate real variables that point to these typeinfos, and look up and dereference them instead. If this hack ends up needing to be permanent, instead of having a manually edited set of such pointer variables, we should teach codemaker to generate corresponding functions, and look up and invoke them to get the std::type_info pointer. When compiling for x86_64-apple-macos, the type_info symbols end up as "weak external" which is fine. With this, LibreOffice starts and seems to work to some extent, and many unit tests succeed.

This moves the classes from juh.jar and ridl.jar to libreoffice.jar The goal is to have one single jar (and Java module, will be added later) which developers can include to work with LO. juh.jar and ridl.jar are kept as basically empty jars with libreoffice.jar on its classpath to keep backwards compatibility.

2019-11-22Extend loplugin:external to warn about classesStephan Bergmann
...following up on 314f15bff08b76bf96acf99141776ef64d2f1355 "Extend loplugin:external to warn about enums". Cases where free functions were moved into an unnamed namespace along with a class, to not break ADL, are in: filter/source/svg/svgexport.cxx sc/source/filter/excel/xelink.cxx sc/source/filter/excel/xilink.cxx svx/source/sdr/contact/viewobjectcontactofunocontrol.cxx All other free functions mentioning moved classes appear to be harmless and not give rise to (silent, even) ADL breakage. (One remaining TODO in compilerplugins/clang/external.cxx is that derived classes are not covered by computeAffectedTypes, even though they could also be affected by ADL-breakage--- but don't seem to be in any acutal case across the code base.) For friend declarations using elaborate type specifiers, like class C1 {}; class C2 { friend class C1; }; * If C2 (but not C1) is moved into an unnamed namespace, the friend declaration must be changed to not use an elaborate type specifier (i.e., "friend C1;"; see C++17 [namespace.memdef]/3: "If the name in a friend declaration is neither qualified nor a template-id and the declaration is a function or an elaborated-type-specifier, the lookup to determine whether the entity has been previously declared shall not consider any scopes outside the innermost enclosing namespace.") * If C1 (but not C2) is moved into an unnamed namespace, the friend declaration must be changed too, see <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71882> "elaborated-type-specifier friend not looked up in unnamed namespace". Apart from that, to keep changes simple and mostly mechanical (which should help avoid regressions), out-of-line definitions of class members have been left in the enclosing (named) namespace. But explicit specializations of class templates had to be moved into the unnamed namespace to appease <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92598> "explicit specialization of template from unnamed namespace using unqualified-id in enclosing namespace". Also, accompanying declarations (of e.g. typedefs or static variables) that could arguably be moved into the unnamed namespace too have been left alone. And in some cases, mention of affected types in blacklists in other loplugins needed to be adapted. And sc/qa/unit/mark_test.cxx uses a hack of including other .cxx, one of which is sc/source/core/data/segmenttree.cxx where e.g. ScFlatUInt16SegmentsImpl is not moved into an unnamed namespace (because it is declared in sc/inc/segmenttree.hxx), but its base ScFlatSegmentsImpl is. GCC warns about such combinations with enabled-by-default -Wsubobject-linkage, but "The compiler doesn’t give this warning for types defined in the main .C file, as those are unlikely to have multiple definitions." (<https://gcc.gnu.org/onlinedocs/gcc-9.2.0/gcc/Warning-Options.html>) The warned-about classes also don't have multiple definitions in the given test, so disable the warning when including the .cxx.

2019-11-17Extend loplugin:external to warn about enumsStephan Bergmann
To mitigate the dangers of silently breaking ADL when moving enums into unnamed namespaces (see the commit message of 206b5b2661be37efdff3c6aedb6f248c4636be79 "New loplugin:external"), note all functions that are affected. (The plan is to extend loplugin:external further to also warn about classes and class templates, and the code to identify affected functions already takes that into account, so some parts of that code are not actually relevant for enums.) But it appears that none of the functions that are actually affected by the changes in this commit relied on being found through ADL, so no adaptions were necessary for them. (clang::DeclContext::collectAllContexts is non-const, which recursively means that External's Visit... functions must take non-const Decl*. Which required compilerplugins/clang/sharedvisitor/analyzer.cxx to be generalized to support such Visit... functions with non-const Decl* parameters.)

By experiment, I found the problematic thing to be -fstack-clash-protection, which can apparently be cancelled with a subsequent -fno-stack-clash-protection at least on that GCC 9.2.0. (And -f[no-]stack-clash-protection appears to only be available since GCC 8, and not at all for Clang, so check for it with HAVE_GCC_STACK_CLASH_PROTECTION.)

2019-10-04always use gb_LinkTarget__get_cxxflags for cxxobjectsLuboš Luňák
E.g. gb_LinkTarget_add_exception_object adds it explicitly, but gb_LinkTarget_add_cxxobject itself does not, even though other variants (c,objc,objcxx) do it. This means that when compiling tools/qa/cppunit/test_cpuid.cxx it doesn't get the correct -O/-g flags, because CppunitTest_tools_test.mk uses gb_CppunitTest_add_cxxobjects to add $(INTRINSICS_CXXFLAGS). And that in its own actually should use the add_exception_objects variant, it didn't presumably because that one used to have cxxflags passing broken until I fixed it in 4bbdab901eb3c7d32d28910fb830f4b0422eee91. The usage in Library_cpp_uno.mk even explicitly works around the lack of debug symbols.
