* [gn] Support for building compiler-rt builtinsPetr Hosek2019-04-051-81/+111
| | | | | | | | | | | | | | | | This is support for building compiler-rt builtins, The library build should be complete for a subset of supported platforms, but not all CMake options have been replicated in GN. We always use the just built compiler to build all the runtimes, which is equivalent to the CMake runtimes build. This simplifies the build configuration because we don't need to support arbitrary host compiler and can always assume the latest Clang. With GN's toolchain support, this is significantly more efficient than the CMake runtimes build.

* Remove unneeded ymath.h include from int_math.hReid Kleckner2019-04-041-1/+0
| | | | | | | | | | | | This avoids a conflict between stdbool.h, which defines bool to _Bool in xkeycheck.h. From what I can tell, ymath.h is an internal header, and the intention is that users should include math.h directly instead. It doesn't appear to provide declarations of anything required for our builtins. This include was added back in r249513 from 2015, and it's possible that ymath.h provided something this code needed at the time, but today it does not. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@357728 91177308-0d34-0410-b5e6-96231b3b80d8

* [builtins] Rounding mode support for addxf3/subxf3Yi Kong2019-03-2612-15/+198
| | | | | | | | | | | | | | | | | Implement rounding mode support for addxf3/subxf3. On architectures that implemented the support, this will access the corresponding floating point environment register to apply the correct rounding. For other architectures, it will keep the current behaviour and use IEEE-754 default rounding mode (to nearest, ties to even). ARM32/AArch64 support implemented in this change. i386 and AMD64 will be added in a follow up change.

| | | | | | | | | | | | | We were treating certain edge cases that are actually normal as denormal results, and flushing them to zero; we shouldn't do that.

* [X86] Add 'znver2' and 'cascadelake' support to __cpu_indicator_init.Craig Topper2019-02-261-6/+20
| | | | | | | | For 'cascadelake' this is adding a 'avx512vnni' feature check to the 0x55 skylake-avx512 model check. These CPUs use the same model number and only differ in the stepping number. But the feature flag is simpler than collecting all the stepping numbers. For 'znver2' this is just syncing with LLVM's Host.cpp. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@354927 91177308-0d34-0410-b5e6-96231b3b80d8

* [compiler-rt][builtins][PowerPC] Implemented __fixunstfti builtin on PowerPCAmy Kwan2019-01-102-0/+107
| | | | | | | | | | | | | | | | | | This patch implements the __uint128_t __fixunstfti (long double) method for PowerPC -- specifically to convert a long double (IBM double-double) to an unsigned 128 bit integer. The general approach of this algorithm is to convert the high and low doubles of the long double and add them together if the doubles fit within 64 bits. However, additional adjustments and scaling is performed when the high or low double does not fit within a 64 bit integer. To invoke this method, one can do so by linking against compiler-rt, via the --rtlib=compiler-rt command line option supplied to clang.

| | | | | | | | | | | | | | | | | | | | | Summary: Windows has always been LLP64, not LP64, so the macros were incorrect. Check for _WIN64, since AArch64 sets that too. The tests have to be fixed up in two main ways: 1. Use 'ULL' suffixes to avoid sign extension when passing hex literals with the sign bit set to signed 128 arguments. Clang -fms-compatibility makes such hex literals signed, not unsigned. 2. Disable various tests for 80-bit long double interoperation with i128 values.

* [compiler-rt] [builtins] Add logb/logbf/logbl methods to compiler-rt to ↵Jordan Rupprecht2018-09-246-10/+77
| | | | | | | | | | | | | | | | | | | | | | | avoid libm dependencies when possible. Summary: The complex division builtins (div?c3) use logb methods from libm to scale numbers during division and avoid rounding issues. However, these come from libm, meaning anyone that uses --rtlib=compiler-rt also has to include -lm. Implement logb* methods for standard ieee 754 floats so we can avoid -lm on those platforms, falling back to the old behavior (using either logb() or `__builtin_logb()`) when not supported. These new methods are defined internally as `__compiler_rt_logb` so as not to conflict with the libm definitions in any way. This fixes just the libm methods mentioned in PR32279 and PR28652. libc is still required, although that seems to not be an issue. Note: this is proposed as an alternative to just adding -lm: D49330.

* [cmake] [ARM] Exclude any VFP builtins if VFP is not supportedAzharuddin Mohammed2018-07-301-0/+9
| | | | | | | | | | | | | | | | | | | | Summary: rL325492 disables FPU features when using soft floating point (-mfloat-abi=soft), which is used internally when building for arm. This causes errors with builtins that utililize VFP instructions. With this change we check if VFP is enabled (by checking if the preprocessor macro __VFP_FP__ is defined), and exclude such builtins if it is not enabled.

| | | | | | | | | The initial implementaiton was using the C++ typeof keyword. This causes the compiler to spew warnings unnecissarilly. This patch removes the uses of typeof and replaces them with explicit typedefs of the function types. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@334981 91177308-0d34-0410-b5e6-96231b3b80d8

* [builtins] Delay emutls deallocation for one roundRyan Prichard2018-06-121-11/+41
| | | | | | | | | | | | | | | | | | | | Summary: With Android/Bionic, delay deallocation to round 2 of 4. It must run after C++ thread_local destructors have been called, but before the final 2 rounds, because emutls calls free, and jemalloc then needs another 2 rounds to free its thread-specific data.
