The mulsc3_test.c was marked as unsupported due to PR32457, the underlying
cause of this PR was fixed in PR28164 so we can remove the unsupported as
it is no longer needed.

Summary:
In FreeBSD we needed to add generic implementations for `__bswapdi2` and
`__bswapsi2`, since gcc 6.x for mips is emitting calls to these. See:
https://reviews.freebsd.org/D10838 and https://reviews.freebsd.org/rS318601
The actual mips code generated for these generic C versions is pretty
OK, as can be seen in the (FreeBSD) review.
I checked over gcc sources, and it seems that it can emit these calls on
more architectures, so maybe it's best to simply always add them to the
compiler-rt builtins library.

Disable tests for xf and xc modes as MIPS doesn't support that mode in

Many things were broken:
- We stopped building most builtins on Windows in r261432 for reasons
that are not at all clear to me. This essentially reverts that patch.
- Fix %librt to expand to clang_rt.builtins-$arch.lib on Windows instead
of libclang_rt.builtins-$arch.a.
- Fix memory protection tests (trampoline, enable executable, clear
cache) on Windows. One issue was that the MSVC incremental linker
generates ILT thunks for functions with external linkage, so memcpying
the functions into the executable stack buffer wasn't working. You
can't memcpy an RIP-relative jump without fixing up the offset.
- Disable tests that rely on C99 complex library functions when using
the MSVC CRT, which isn't compatible with clang's C99 _Complex.
In theory, these could all be separate patches, but it would not green
the tests, so let's try for it all at once. Hopefully this fixes the
clang-x64-ninja-win7 bot.

Summary:
During MIPS implementation work for FreeBSD, John Baldwin (jhb@FreeBSD.org)
found that gcc 6.x emits calls to __ffssi2() when compiling libc and some
userland programs in the base system.
Add it to compiler-rt's builtins, based off of the existing __ffsdi2()
implementation. Also update the CMake files and add a test case.

It was XFAILed in r298974. However, the problem was not exposed on
the buildbot because hardfp flag was not passed during the test.

This predicate compares the host's marketing OS version to one passed as

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

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.

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.

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.

The code is based on the existing code for __floattixf()

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.

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.

Negative numbers were handled properly initially, but got broken
during addressing review, so none of them did actually work. Issues:
* Wrong negation.
* Wrong exponent calculation.

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.
This patch adds tests for all three cases, along with adding a missing
header include to fp_test.h.

Like we do for the various __*tf* tests, check that long double is the
128bit type we expect directly in the header. The latter is now used by
unrelated tests (__*hf* since r237161), and those tests will break for
no reason if uint128_t doesn't exist, and long double isn't fp128.
