New commits: commit d03f5ab76b0d0dee199b65fc801236a38830b5fc Author: Even Rouault <even.roua...@spatialys.com> Date: Sun Oct 6 12:52:31 2019 +0200 Do not override user-defined CMAKE_C[XX]_FLAGS for clang 337585e3d881c2c2c9099888b09902119dc05bf8 unconditionnaly overrides any potential user-defined CMAKE_C[XX]_FLAGS. This for example breaks the GDAL oss-fuzz builds which build Poppler from source (see https://github.com/OSGeo/gdal/blob/master/gdal/fuzzers/build.sh#L54) So do the same as the GCC path where we save input CMAKE_C[XX]_FLAGS and reinject them in custom CMAKE_C{XX}_FLAGS_{build_configuration} The values are identical to GCC, execpt for the _DEBUG configuration where we remove '-O2 -fno-reorder-blocks -fno-schedule-insns -fno-inline' since clang does not support -fno-reorder-blocks and -fno-schedule-insns, so it is likely better to disable any optimization for proper debugging. diff --git a/cmake/modules/PopplerMacros.cmake b/cmake/modules/PopplerMacros.cmake index 5ccbc4ef..a9d20948 100644 --- a/cmake/modules/PopplerMacros.cmake +++ b/cmake/modules/PopplerMacros.cmake @@ -166,8 +166,23 @@ if ("${CMAKE_CXX_COMPILER_ID}" STREQUAL "Clang") set(DEFAULT_COMPILE_WARNINGS "${_warn}") set(DEFAULT_COMPILE_WARNINGS_EXTRA "${_warn} ${_warnx}") + set(_save_cxxflags "${CMAKE_CXX_FLAGS}") set(CMAKE_CXX_FLAGS "-fno-exceptions -fno-check-new -fno-common -D_DEFAULT_SOURCE") + set(CMAKE_CXX_FLAGS_RELWITHDEBINFO "-O2 -g ${_save_cxxflags}") + set(CMAKE_CXX_FLAGS_RELEASE "-O2 -DNDEBUG ${_save_cxxflags}") + # clang does not support -fno-reorder-blocks -fno-schedule-insns, so do not use -O2 + set(CMAKE_CXX_FLAGS_DEBUG "-g ${_save_cxxflags}") + set(CMAKE_CXX_FLAGS_DEBUGFULL "-g3 -fno-inline ${_save_cxxflags}") + set(CMAKE_CXX_FLAGS_PROFILE "-g3 -fno-inline -ftest-coverage -fprofile-arcs ${_save_cxxflags}") + set(_save_cflags "${CMAKE_C_FLAGS}") set(CMAKE_C_FLAGS "-std=c99 -D_DEFAULT_SOURCE") + set(CMAKE_C_FLAGS_RELWITHDEBINFO "-O2 -g ${_save_cflags}") + set(CMAKE_C_FLAGS_RELEASE "-O2 -DNDEBUG ${_save_cflags}") + # clang does not support -fno-reorder-blocks -fno-schedule-insns, so do not use -O2 + set(CMAKE_C_FLAGS_DEBUG "-g ${_save_cflags}") + set(CMAKE_C_FLAGS_DEBUGFULL "-g3 -fno-inline ${_save_cflags}") + set(CMAKE_C_FLAGS_PROFILE "-g3 -fno-inline -ftest-coverage -fprofile-arcs ${_save_cflags}") + endif() if(CMAKE_C_COMPILER MATCHES "icc") _______________________________________________ poppler mailing list poppler@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/poppler
