* [compiler-rt][builtins] Add __isOSVersionAtLeast()Erik Pilkington2017-03-095-0/+70
| | | | | | | | | | | | | | | | | This predicate compares the host's marketing OS version to one passed as argument. Currently, only darwin targets are supported. This is done by parsing the SystemVersion.plist file. Also added in this patch is some lit testing infrastructure for builtins, which previously had none. This part of the patch was written by Alex Lorenz (with some minor modifications).

* [Builtin][ARM] #ifdef ARM vfp tests and cpu_model_testsWeiming Zhao2017-02-1535-68/+75
| | | | | | | | | | | | | | | | | Summary: Add in #ifdef to exclude cpu_model_test on non-X86 and *vfp_test on ARM targets without VFP support.

* [test] #ifdef new builtin tests for __arm__ platformMichal Gorny2017-02-083-0/+18
| | | | | | | | | | | | | Add an #if that excludes the newly added aeabi* tests on non-ARM platforms. This is consistent with other ARM tests, and aims to make running builtin tests easier. Lacking a proper infrastructure to run tests selectively, it is more convenient if we do not have to implement directory-platform exclusions and can just rely on tests compiling to no-op on other platforms.

* [test] Fix page address logic in clear_cache_testMichal Gorny2017-01-211-2/+14
| | | | | | | | | | | | | | | | | | | | Fix the logic used to calculate page boundaries in clear_cache_test to use correct masks -- e.g. -4096 rather than -4095. The latter gives incorrect result since: -4095 -> 0xfffff001 -4096 -> 0xfffff000 (== ~4095) The issue went unnoticed so far because the array alignment caused the last bit not to be set. However, on 32-bit x86 no such alignment is enforced and the wrong page address caused the test to fail. Furthermore, obtain the page size from the system instead of hardcoding 4096.

* [test] [builtins] Remove obsolete/UB tests in __fixuns?fdi basedMichal Gorny2017-01-172-5/+0
| | | | | | | | | | | | | | | | | | | | Remove the failing tests for __fixunssfdi() and __fixunsdfdi() that relied on undefined (and most likely obsolete in terms of compiler-rt implementation behavior). Both tests presumed that 0x1.p+64 would be converted to 0xFFFFFFFFFFFFFFFFLL, that is the largest value in uint64 range. However, the C/C++ standards do not specify the behavior for converting a floating-point value to an integer of smaller range, and in this case both libgcc and compiler-rt implementations return 0 instead. Since the current behavior is correct with regards to standards and there is no good way of expressing 0xFFFFFFFFFFFFFFFFLL in single- or double-precision float, I've removed the failing test altogether.

This is needed e.g. on AArch64 where 'long double' is a quad-precision type. The code is based on the existing code for __floattixf() and __floatuntixf(), updated to account for different bit field lengths of quad-precision float.

* [compiler-rt][aarch64] New tests for 128-bit floating-point builtins, fixes ↵Sergey Dmitrouk2015-11-0512-5/+279
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | of tests and __fixuint Summary: The following tests for 128-bit floating-point type behaved in a strange way, thought it were bugs, but seem to be mistakes in tests: * `fixtfsi` test checked for `0x80000001` as a value returned for number less than can be represented, while `LONG_MIN` should be returned on saturation; * `fixunstfdi` wasn't enabled for AArch64, only for PPC, but there is nothing PPC specific in that test; * `multf3` tried to underflow multiplication by producing result with 16383 exponent, while there are still 112 bits of fraction plus implicit bit, so resultant exponent should be 16497. Tests for some other builtins didn't exist: * `fixtfdi` * `fixtfti` * `fixunstfti` They were made by copying similar files and adjusting for wider types and adding/removing some reasonable/extra checks. Also `__fixuint` seems to have off by one error, updated tests to catch this case.

* [compiler-rt] Add AArch64 to CMake configuration and several missing builtinsSergey Dmitrouk2015-08-183-2/+138
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Currently CMake doesn't build builtins for AArch64 and if one does this anyway it's likely that at least `__multc3`, `__floatditf` and `__floatunditf` will be missing. There is actually more builtins to add, but these come from different libc implementations, thus providing them makes compiler-rt for AArch64 good enough at least for basic usage. Builtins implementation were originally taken from FreeBSD project: * [[ https://reviews.freebsd.org/D2173 | __multc3 ]] * [[ https://reviews.freebsd.org/D2174 | __floatditf and __floatunditf ]] Until they have been tested to find mistakes in `__float*` functions. `__floatditf` was based on `__floatsitf`, which had the same mistakes (fixed it in r243746). Version of the builtins in this patch are fixed and complemented with basic tests. Additionally they were tested via GCC's torture (this is what revealed these issues). P.S. Ed (author of FreeBSD patches) asked for feedback on the list some time ago (here [[ http://lists.cs.uiuc.edu/pipermail/llvmdev/2015-March/084064.html | here ]]) and got no response, but it seems to be worth adding these builtins as is and extracting common part later.

* Fix incorrect truncation at the overflow boundaryPirama Arumuga Nainar2015-06-234-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch fixes incorrect truncation when the input wider value is exactly 2^dstBits. For that value, the overflow to infinity is not correctly handled. The fix is to replace a strict '>' with '>='. Currently, __truncdfsf2(340282366900000000000000000000000000000.0) returns infinity __truncdfsf2(340282366920938463463374607431768211456.0) returns 0 __truncdfsf2(400000000000000000000000000000000000000.0) returns infinity Likewise, __truncdfhf2 and __truncsfhf2 (and consequently gnu_f2h_ieee) are discontinuous at 65536.0.

| | | | | | | | | | | | | | | | | | Mostly uninteresting, except: - in __extendXfYf2, when checking if the number is normal, the old code relied on the unsignedness of src_rep_t, which is a problem when sizeof(src_rep_t) < sizeof(int): the result gets promoted to int, the signedness of which breaks the comparison. I added an explicit cast; it shouldn't affect other types. - we can't pass __fp16, so src_t and src_rep_t are the same. - the gnu_*_ieee symbols are simply duplicated definitions, as aliases are problematic on mach-o (where only weak aliases are supported; that's not what we want).

* tests: correct builtins test if built under -mthumb on ARMSaleem Abdulrasool2015-01-052-11/+28
| | | | | | | | | | | The clear_cache and enable_execute_stack tests attempt to memcpy the definition of a function into a buffer before executing the function. The problem with this approach is that on some targets (ARM with thumb mode compilation, MIPS with MIPS16 codegen or uMIPS), you would use a pointer which is incorrect (it would be off-by-one) due to the ISA selection being encoded into the address. This ensures that the function address is retrieved correctly in all cases. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@225215 91177308-0d34-0410-b5e6-96231b3b80d8
