2016-04-20builtins: fix -Werror,-Wunused-variable warningSaleem Abdulrasool
This removes the unused variable `flags`. NFC git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@266892 91177308-0d34-0410-b5e6-96231b3b80d8
2016-04-20builtins: remove use of __attribute__((pcs("aapcs"))) on WindowsSaleem Abdulrasool
Windows does not honour the __attribute__((pcs)) on ARM. Although this will result in ABI mismatches, compiler-rt should largely be unneeded for resolving dependencies as we generate MS ABI compliant library calls now for the most part. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@266891 91177308-0d34-0410-b5e6-96231b3b80d8
2016-04-14Fix StaticAnalyzer complaints. NFC.George Burgess IV
Clang's StaticAnalyzer seems to (correctly) complain about code like: T *p = calloc(sizeof(U), N); ...Where T and U are different types. This patch removes some instances of this pattern from compiler-rt. Patch by Apelete Seketeli.

2016-03-29[Darwin] [Builtins] Remove multi3 from the exclude list.Chris Bieneman
This addresses PR27077. For some historical reason Darwin wasn't shipping multi3 in the compiler builtin library or in the OS builtin library. This caused building ffmpeg to fail because Polly was generating calls to multi3. It is easy enough to just add the builtin. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@264750 91177308-0d34-0410-b5e6-96231b3b80d8

2016-03-18builtins: make __clear_cache work on Linux-ARMSaleem Abdulrasool
__clear_cache on Android is identical to the version on Linux. Use __linux__ instead of __ANDROID__ as __linux__ is defined for Linux and Android. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@263833 91177308-0d34-0410-b5e6-96231b3b80d8

2016-03-09Add ARM EHABI support to gcc_personality_v0.Logan Chien
Until now the only exception APIs supported by gcc_personality_v0 are DWARF EH and SJLJ. This adds support for ARM EHABI as well. This is achieved by a) changing the function signature on ARM EHABI, b) unwinding the stack before returning _URC_CONTINUE_UNWIND. See "Exception Handling ABI for the ARM Architecture" for details (http://infocenter.arm.com/help/topic/com.arm.doc.ihi0038b/IHI0038B_ehabi.pdf). Patch by Timon Van Overveldt. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@263010 91177308-0d34-0410-b5e6-96231b3b80d8

2016-02-04builtins: Fix struct __emutls_control to match GCCChih-Hung Hsieh
The type of size and align in struct __emutls_control must be typedef unsigned int gcc_word __attribute__((mode(word))); to match GCC. When gcc_word is larger than size_t, which is the case for x32, the upper extra bits are all zeros. We can use variables of size_t to operate on size and align.

2015-12-01builtins: Fix the sysroot's reference to si_int in int_types.hSumanth Gundapaneni
si_int is already defined in sysroot's siginfo.h emutls.c includes pthread.h which includes asm/siginfo.h which in turn includes asm-generic/siginfo.h and that defines si_int. si_int is also defined in builtin's int_types.h and this leads to errors.

2015-11-05[compiler-rt][aarch64] New tests for 128-bit floating-point builtins, fixes ↵Sergey Dmitrouk
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.

2015-10-10builtins: spell inline as __inlineSaleem Abdulrasool
__inline is a vendor specific spelling for inline. clang and gcc treat it the same as inline, and is available in MSVC 2013 which does not implement C99 (VS2015 supports the inline keyword though). This will allow us to build the builtins using MSVC. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@249953 91177308-0d34-0410-b5e6-96231b3b80d8
