* CMake: remove support for building Qt with the old Intel compilerThiago Macieira2021-10-131-11/+0
| | | | | | | | | | | | | | | | | | This hasn't worked for some time. It's not in our CI and I don't think it was working at all. When I tried to build it, I ran into several problems with C++17 and an Internal Compiler Error I did not have any interest in working around. After discussing with the Intel compiler team, it was decided that fixing those issues in the old compiler is not going to happen. Instead, their recommendation is to adopt the new LLVM-based compiler, which the last commit added support for. This commit does not remove qmake support for the old ICC. It's possible someone is using qmake with a non-Qt6 project and ICC. Change-Id: Icb2516126f674e7b8bb3fffd16ad6350ddbd49e5 Reviewed-by: Alexandru Croitor <alexandru.croitor@qt.io>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do this by templating the floating-point tests, which removes some existing duplication as well as avoiding new duplication. Did some renaming in the process. Added some tests of fuzzyCompare that come closer to its boundary. Increased number of tests from 69 to 97. Use std::numeric_limits to replace assorted hard-coded constants and old C-library boundary-value macros. It turns out MSVC's float conflates quiet and signaling NaN (although MinGW's doesn't); and WebAssembly's old fastcomp compiler conflates NaNs for both float and double; so XFAIL the test for distinct NaNs in those cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of our compilers for emscripten coerces all signaling NaNs to quiet ones, so won't do any actual signaling. Anyone relying on them to do so shall be disappointed, so it's better that they know about it at compile-time - or, at least, have the ability to find it out. Put the signaling NaN producers (and remaining (test) code using them) under the control of a feature that's disabled when numeric_limits claims double has no signaling NaN. Assume the bootstrap library doesn't need signaling NaNs. Sadly, until C++20 <bit>, there's no contexpr way to test that alleged signalling and quiet NaNs are actually distinct. Added some auto-tests for signaling NaN, including that it's distinct from quiet NaN. Any platform on which the last fails should disable this feature.

| * Replace a misguided test with a valid oneEdward Welbourne2019-03-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The code had min and max of an integral type and tested min + min / 2, which naturally overflowed, provoking a compiler warning. The test was meant to be testing min - min / 2; but min is even, so this is just min / 2; and doubling that won't overflow (which is what the test is about). As it happens, min + min / 2 is in fact max - max / 2, which *would* be a good value to test, since max is odd. So add a test for that and remove the broken test.

| | | | | | | | | | | | | | | | | | | | Commit 29bc68cf169b8cf87d306a1c72e12eb9b6fbfce7 added support for unsigned and commit 5ff7a3d96e0ce0dcb3d388b53d038cdd40c7a975 later added support for int. This commit adds support for qsizetype, which isn't int on 64-bit platforms. We do this by reorganizing the code and using the generic version of __builtin_{add,sub,mul}_overflow from GCC 5 and Clang 3.8, which ICC 18 seems to support now too on Linux. That leaves older versions of GCC and Clang, as well as MSVC, ICC on Windows, and the GHS compiler, to use the generic implementations, as I've removed the assembly code those versions of GCC and Clang on x86 are now uncommon. Note: any older version of ICC probably breaks. We only support the latest. Change-Id: I9e2892cb6c374e93bcb7fffd14fc11bcd5f067a7 Reviewed-by: Allan Sandfeld Jensen <allan.jensen@qt.io>

| | | | | | | | | | | | | | In C++, signed overflow math is Undefined Behavior. However, many CPUs do implement some way to check for overflow.

Or, for X86, by using inline assembly to use the CPU features. Used in QtQml. Change-Id: I2ef2523ccaa98f6757a45e24862a2fa730a26bb0 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

For unsigned additions, that's easy, since the C++ language specifies the behavior of the overflow. That's also the reason why this code is implemented only for unsigned integers. For the multiplication, if the compiler does not support widening multiplications, we do it with a division instead. This is necessary for GCC < 4.5 and compilers not compatible with GCC or MSVC.

| | | | | | | | | | | | | | | | | | This function is useful if a floating point comparison requires a certain precision. The return value can be considered as the precision. For instance, if you want to compare two 32-bit floating point values and all you need is a 24-bit precision, you can use this function like this: if (qFloatDistance(a,b) < (1 << 7)) { // The last 7 bits are not // significant // precise enough } Task-number: QTBUG-32632 Change-Id: I020a58d2f9f9452ac3c510b4bb560dc806f0d93c Reviewed-by: Shawn Rutledge <shawn.rutledge@digia.com> Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

| | | | | | | | | | | | ICC apparently optimises 0 * anything directly to zero, even when it should be doing a multiplication to conform to IEEE requirements. GCC in fast-math mode does the same, but that also makes the rest of the function unreliable, so we try to turn off fast-math mode if we can.
