* [compiler-rt][aarch64] New tests for 128-bit floating-point builtins, fixes ↵Sergey Dmitrouk2015-11-051-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Refactor float to integer conversion to share the same code.Joerg Sonnenberger2015-03-111-0/+64
80bit Intel/PPC long double is excluded due to lacking support for the abstraction. Consistently provide saturation logic. Extend to long double on 128bit IEEE extended platforms. Initial patch with test cases from GuanHong Liu. Reviewed by Steve Canon. Differential Revision: http://reviews.llvm.org/D2804 llvm-svn: 231965
