* cmake/configure.ac: Enable -fstack-protector-strong by defaultNotTsunami2019-11-201-2/+5
| | | | | | | | | | | | | | | | This commit contains the following changes: - Drops -fstack-protector in favor of -fstack-protector-strong. Consequently, the ssp-buffer-size parameter has been removed as -fstack-protector-strong ignores array size. - Add new global opt-out for stack smash protection. This is enabled by default for both autotools and CMake builds. Users can opt out of stack smash protection by passing -DWITH_STACK_PROTECTOR=OFF to CMake or --disable-stack-smash-protection when running ./configure. - Renames HAVE_SSP_FLAG to HAVE_STACK_PROTECTOR_FLAG in CMakeLists.txt to be more readable.
* oss-fuzz: Add fuzzing targetsErik de Castro Lopo2019-11-181-11/+39
| | | | | | | | | These fuzzing targets were originally from: https://github.com/guidovranken/flac-fuzzers.git but having them in a separate repo was a huge pain in the neck when working on fixing any problems found.
* configure.ac: allow several compiler flags for clangsezero2019-10-101-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | The flac configury marked clang as 'not being gcc' and excluded a lot of compiler switches, most importantly the visibility flags, from being used with it. This was done possibly after a problem reported at: https://github.com/erikd/libsndfile/issues/49 . This patch does the following: - m4/gcc_version.m4 (XIPH_GCC_VERSION): set GCC_MAJOR_VERSION and GCC_MINOR_VERSION to 0 for non-gcc. Previously, they were left unset. - configure: the gcc version checks are, naturally, against non- zero values, so, allow many compiler switches to be used with clang without affecting real-gcc cases. - configure: When setting CFLAGS="-O3 -funroll-loops", also set CXXFLAGS="-O3". Prevents g++ warnings with _FORTIFY_SOURCE, i.e.: '_FORTIFY_SOURCE requires compiling with optimization (-O)' Tested compilation using gcc-7.3.1 and clang-5.0.2 on x86_64-linux, and gcc-4.4.7 and clang-3.4.2 on an i686-linux. Also tested cross- compiling for Mac OS X using clang-5.0.2.
* make dllexport work with compilers other than MSVCsezero2019-10-101-0/+16
| | | | | | | | the issue is, flac and metaflac exes rely on flac_internal_???_utf8() procedures from windows_unicode_filenames.c and there is no easy way to exclude them from exports without breaking things. So export them explicitly (they are exported anyway w/o this patch), but add a FIXME note about the kludge in windows_unicode_filenames.c.

* configure.ac : Pass -fno-inline-small-functions when using GCC 4.7Mario Sanchez Prada2015-07-081-0/+4
| | | | | | | | | | | | | | | For some reason, the build fails when using GCC 4.7 due to the implicit -finline-functions option passed to the compiler when -O3 is enabled, which does not happen in newer versions of GCC, probably due to some of the "General Optimizer Improvements" included in 4.8 (see [1]). Fortunately, we don't need to disable -finline-functions completely but just do it for "small functions", which is what this patch does.

* configure.ac : Tweak for x32 architecture.Erik de Castro Lopo2015-03-121-13/+24
| | | | | | | | | The x32 architecture uses and ILP32 (32 bit ints, longs and pointers) on an x86_64 CPU. Since the CPU is x86_64 we need to set FLAC__CPU_X86_64 even though the pointer size is 32 bits. Patch-from: Stuart Shelton Closes: https://sourceforge.net/p/flac/bugs/427/

| | | | | | | | | | | Previously CFLAGS had a -O3 at the start and a -O2 at the end. According to the GCC docs: https://gcc.gnu.org/onlinedocs/gcc-4.9.1/gcc/Optimize-Options.html "If you use multiple -O options, with or without level numbers, the last such option is the one that is effective" which means that GCC doesn't try to use SIMD to vectorize the code, etc."
