| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use __attribute__ ((fallthrough)) to indicate switch case fall through instead of a comment. This ensures that the fallthrough warning is not triggered even if the file is pre-processed (hence stripping the comments) before it is compiled. The actual fallback implementation is hidden behind a FALLBACK macro in case the compiler doesn't support it. Finally, the -Wimplict-fallthrough warning was upgraded to only allow the attribute to satisfy it; a comment alone is no longer sufficient. Signed-off-by: Joshua Watt <JPEWhacker@gmail.com>

| * Make sure packed structs follow the gcc memory layoutUlf Hermann2017-09-202-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | gcc defaults to using struct layouts that follow the native conventions, even if __attribute__((packed)) is given. In order to get the layout we expect, we need to tell gcc to always use the gcc struct layout, at least for packed structs. To do this, we can use the gcc_struct attribute. This is important, not only for porting to windows, but also potentially for other platforms, as the bugs resulting from struct layout differences are rather subtle and hard to find.

| * Check if gcc complains about __attribute__ (visibility(..))Ulf Hermann2017-08-182-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If so, define attribute_hidden to be empty. Also, use attribute_hidden in all places where we hide symbols. If this attribute is missing, it simply means that we cannot hide private symbols in the binary using attributes. This disables some optimizations and may increase the risk of symbol name clashes with other libraries, but is not fatal. However, we still employ linker version scripts to explicitly define the exported symbols. This serves much of the same purpose. Also, as all our symbols are prefixed with the library name, and "__" for private ones, the chance of clashes is low anyway. Signed-off-by: Ulf Hermann <ulf.hermann@qt.io>
| * Check for -z,defs, -z,relro, -fPIC, -fPIE before using themUlf Hermann2017-08-182-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Those flags are not available on all platforms, and omitting them when not available will not cause any harm. In particular: -z,defs disallows undefined symbols in object files. This option is unsupported if the target binary format enforces the same condition already. Furthermore it is only a compile time sanity check. When it is omitted, the same binary is produced. -z,relro instructs the loader to mark sections read-only after loading the library, where possible. This is a hardening mechanism. If it is unavailable, the functionality of the code is not affected in any way. -fPIC instructs the compiler to produce position independent code. While this is preferable to relocatable code, relocatable code also works and may even be faster. Relocatable code might just be loaded into memory multiple times for different processes. -fPIE is the same thing as -fPIC for executables rather than shared libraries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | config.h doesn't have include guards, so including it twice is bad. We deal with this by checking for PACKAGE_NAME, but only in some places. Once we start using gnulib, we will need to include config.h before any gnulib-generated headers. This is problematic if we include it transitively through our own private headers. In order to set a clear rule about inclusion of config.h, it is now included in every .c file as first header, but not in any header. This will definitely avoid double-inclusion and satisfy the condition that it has to be included before gnulib headers. It comes at the price of adding some redundancy, but there is no clean way to avoid this. Signed-off-by: Ulf Hermann <ulf.hermann@qt.io>
