2017-10-03[compiler-rt] Add back ARM EABI aliases where legal.Eli Friedman
r303188 removed all the uses of aliases for EABI functions from compiler-rt, because some of them had mismatched calling conventions. Obviously, we can't use aliases for functions which don't have the same calling convention, but that's only an issue for floating-point functions with the hardfloat ABI. In other cases, the stubs increase size and reduce performance for no benefit. This patch adds back the aliases, with appropriate checks to make sure they're only used in cases where the calling convention matches. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@314851 91177308-0d34-0410-b5e6-96231b3b80d8
2017-05-16builtins: expand out the AEABI function stubsSaleem Abdulrasool
These actually may change calling conventions. We cannot simply provide function aliases as the aliased function may have a different calling convention. Provide a forwarding function instead to permit the compiler to synthesize the calling convention adjustment thunk. Remove the `ARM_EABI_FNALIAS` macro as that is not safe to use.

2017-03-29[Builtin] Unxfail tests for armhfWeiming Zhao
Summary: Originally, a few tests fail for armhf target due to: 1) COMPILER_RT_ARMHF_TARGET was not set when building the lib 2) COMPILER_RT_ABI should not be defined as `__attribute__((pcs("aapcs")))` for armhf when building for both lib and tests This address https://bugs.llvm.org//show_bug.cgi?id=32261 mulsc3_test.c is a newly exposed issue, which will be addressed separately.

2016-08-01Use 'unsigned long' to match the APIs of the MS bitscan intrinsicsReid Kleckner
We were getting warnings about how 'uint32_t*' is different from 'unsigned long*' even though they are effectively the same on Windows. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@277363 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
