In case of building 32-bit libraries on 64-bit host using default host triple these macros are not defined. As a result assertions check a consistency between the `struct_kernel_stat_sz` constant and the `struct_kernel_stat_sz` start to fail. To resolve this problem and enable building both 32/64-bit versions of MIPS compiler-rt libraries on 64-bit host at once always explicitly define the `_LARGEFILE_SOURCE` and the `_FILE_OFFSET_BITS=64` macros for MIPS 32-bit. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/branches/release_80@361568 91177308-0d34-0410-b5e6-96231b3b80d8

Additionally, since the code in `sys::PrintStackTrace` makes use of `itaniumDemangle`, also add `-lLLVMDemangle`. (Note that this is more of a general problem with libLLVMSupport, but I'm looking for a quick fix now so it can be merged to the 8.0 branch.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is the compiler-rt part. The clang part is D54589. This is a second commit, the original one was r351106, which was mass-reverted in r351159 because 2 compiler-rt tests were failing. Now, i have fundamentally changed the testing approach: i malloc a few bytes, intentionally mis-align the pointer (increment it by one), and check that. Also, i have decreased the expected alignment. This hopefully should be enough to pacify all the bots. If not, i guess i might just drop the two 'bad' tests.

| | | | | | | | | | | | | | | | | | | | | | | | | Summary: This fixes linker errors that occurs when the `sanitizer_type_traits_test.cc` is built without optimizations. The error occurs because the test tries to take a reference. A possible workaround is to give the GTest macros take boolean rvalues by doing something like: ``` ASSERT_TRUE(bool(is_same<uptr, uptr>::value)); ``` However this only hides the problem. Unfortunately Using `constexpr` won't fix the problem unless we are using C++17.

| | | | | | | | | | | | | Remove the partial support for rpc/xdr.h from libtirpc.

| | | | | | | | | | | | | | | | | | 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.

* hwasan: Ignore loads and stores of size 0.Peter Collingbourne2019-01-092-1/+12
| | | | | | | | | | | | | | | | | | Now that memory intrinsics are instrumented, it's more likely that CheckAddressSized will be called with size 0. (It was possible before with IR like: %val = load [0 x i8], [0 x i8]* %ptr but I don't think clang will generate IR like that and the optimizer would normally remove it by the time it got anywhere near our pass anyway). The right thing to do in both cases is to disable the addressing checks (since the underlying memory intrinsic is a no-op), so that's what we do.
