2018-03-23Revert "Allow compiler plugins for online"Stephan Bergmann
This reverts commit b39e627be45f847554f11fdac040b6f4da4054ba. The assumed (see comment at <https://gerrit.libreoffice.org/#/c/46769/4/compilerplugins/clang/ plugin.cxx@633>) performance bottleneck of isSamePathname -> getAbsolutePath does show up in Flamegraph inspections of LO builds. But changing (non-member function) isSamePathname to only call getAbsolutePath if (PluginHandlder member function) isLOOLMode is true would need some code reorg, and Online development doesn't seem to make too much actual use of the plugin, so conclusion on IRC was to revert.

2017-12-08New --enable-compiler-plugins=debug modeStephan Bergmann
...to enable debug-only code in the plugins. Some situations in the plugin code should never happen, yet must not by default report errors or trigger assertions, as some newly written LO code could trigger them nevertheless (in which case the plugin code will likely need to be adapted, to cater for these presumed-impossible situations). Such code can now be included in the plugins behind an if(isDebugMode()) guard, and can explicitly be enabled with --enable-compiler-plugins=debug. I deliberately made this a runtime rather than a compile time option (using some #ifdef guards in the plugin code, say), as it IMO keeps the code more readable, and also allows overridding COMPILER_PLUGINS_DEBUG=... on the make command line.

2017-11-07Memoize ignoreLocation resultsStephan Bergmann
...which, according to callgrind, reduces instruction fetch count spent on compiling sw/source/core/layout/paintfrm.cxx (randomly selected because it is rather large) by 5% from 41,992,064,226 to 39,861,989,855 (function main() in clang-6.0). This is best done by forwarding ignoreLocation calls from Plugin to the PluginHandler signleton, but due to the tight mutual coupling between plugin.hxx and pluginhandler.hxx that unfortunately required some reorganization (and two outstanding TODO clean-ups of temporarily introduced using declarations in plugin.hxx).

2017-09-30Support loplugin in clang-clStephan Bergmann
This works at least with a recent Clang trunk (towards Clang 6.0). In order for the plugin.dll to find the LLVM/Clang symbols, it needs to be loaded into clang.exe not clang-cl.exe, so set CC/CXX to 'clang.exe --driver-mode=cl ...'. Buidling the plugin requires some linker flags that must go at the very end of the COMPILER_PLUGINS_CXX command line, after a /link switch, so introduce another COMPILER_PLUGINS_CXX_LINKFLAGS variable for that. Also, clang.lib is not installed as part of LLVM's 'cmake --build ... --target install' step, so is not available under CLANGDIR and needs to be taken from the build tree instead, so introduce another CLANGLIBDIR variable for that. autogen.input settings that work for me on Windows 8.1 with Microsoft Visual Studio 14.0 are: > CLANGDIR=C:/llvm/inst > CLANGLIBDIR=C:/llvm/build/lib > COMPILER_PLUGINS_CXX=C:/PROGRA~2/MICROS~3.0/VC/bin/amd64/cl.exe /IC:\PROGRA~2\MICROS~3.0\VC\INCLUDE /IC:\PROGRA~2\MICROS~3.0\VC\ATLMFC\INCLUDE /IC:\PROGRA~2\WI3CF2~1\10\include\100102~1.0\ucrt /IC:\PROGRA~2\WI3CF2~1\NETFXSDK\46D346~1.1\include\um /IC:\PROGRA~2\WI3CF2~1\8.1\include\shared /IC:\PROGRA~2\WI3CF2~1\8.1\include\um /IC:\PROGRA~2\WI3CF2~1\8.1\include\winrt > COMPILER_PLUGINS_CXX_LINKFLAGS=/LIBPATH:C:/PROGRA~2/MICROS~3.0/VC/LIB/amd64 /LIBPATH:C:/PROGRA~2/MICROS~3.0/VC/ATLMFC/LIB/amd64 /LIBPATH:C:/PROGRA~2/WI3CF2~1/10/lib/100102~1.0/ucrt/x64 /LIBPATH:C:/PROGRA~2/WI3CF2~1/NETFXSDK/46D346~1.1/lib/um/x64 /LIBPATH:C:/PROGRA~2/WI3CF2~1/8.1/lib/winv6.3/um/x64 (The last two are "C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/bin/ amd64/cl.exe" and translations of %INCLUDE% and %LIB% as set in the "VS2015 x64 Native Tools Command Prompt" shell. AC_CHECK_HEADER(clang/AST/RecursiveASTVisitor.h, ...) in configure.ac wouldn't like CXX to start with INCLUDE=... LIB=... environment variable settings, so it wouldn't work to instead pass %INCLUDE% and %LIB% to cl.exe that way. See <https://wiki.documentfoundation.org/Development/clang-cl> for general information about building with clang-cl on Windows.) There's still some room for improvement marked "TODO". (And some of the unused* plugins, which are not run by default anyway, use Unix-style functionality, so have been disabled for now.)

2016-04-26Enable Clang plugin warnings in Bison source codeStephan Bergmann
-Werror is generally suppressed in Bison-generated C/C++ code (as in all other generated code) to silence warnings from the Bison skeleton code. And the Clang plugins suppress warnings in generated WORKDIR code based on the presumed source location (i.e., taking #line directives into account). So introduce a new PLUGIN_WARNINGS_AS_ERRORS mode where warnings from Clang plugins are reported as errors even if -Werror is suppressed. That way, any warnings in the Bison skeleton code still do not lead to compilation errors, while (at least plugin- emitted) warnings in the genuine source code do. Unfortunately this cannot also be enabled for Flex source code, as at least Flex 2.5.39 generates poor code that does not properly prefix all skeleton code with appropriate #line directives, so that some skeleton code would be mistaken for genunie source code, and compilation would fail due to errors. Also, %glr-parser Bison input appears to generate no #line directives at all (at least with Bison 3.0.4), so all of connectivity/source/parse/sqlbison.y is considered generated code and plugin warnings are still suppressed throughout.
