2017-12-24Fix PR35739: chkstk and chkst2 should only be built for WindowsDimitry Andric
As reported in PR35739, rL252927 added the Windows specific chkstk and chkstk2 sources unconditionally, and since these are assembly without a NO_EXEC_STACK_DIRECTIVE at the end, automated vulnerability scanners warned about the objects having an executable stack. Avoid the problem by only including these files when Windows is targeted.

Remove the explicit i686 target that is completely duplicate to the i386 target, with the latter being used more commonly. 1. The runtime built for i686 will be identical to the one built for i386. 2. Supporting both -i386 and -i686 suffixes causes unnecessary confusion on the clang end which has to expect either of them. 3. The checks are based on wrong assumption that __i686__ is defined for all newer x86 CPUs. In fact, it is only declared when -march=i686 is explicitly used. It is not available when a more specific (or newer) -march is used. Curious enough, if CFLAGS contain -march=i686, the runtime will be built both for i386 and i686.

2017-08-10[compiler-rt][ARM] Fix filtering of ARM targetsOleg Ranevskyy
Summary: Similarly to i686, the ARM build target has multiple names, such as armhf, armv7 and so on. Currently we get duplicated symbol definitions for these targets while compiling the library. Each duplicated definition has its generic version from `lib/builtins` and an ARM-specialized version from `lib/builtins/arm`. This patch fixes filtering for ARM to ignore the generic definitions if they have their ARM specializations.

2017-05-25Add generic __bswap[ds]i2 implementationsDimitry Andric
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.

2017-04-07[builtins] Get the builtins tests passing on WindowsReid Kleckner
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.

This fixes an incorrect standard usage of GNU99 when the compiler check was for the ISO standard C99. Furthermore, bump the dependency up to C11. The motivation for this change is ARM EHABI compatibility with clang 3.8. We rely on a type definition redefinition which causes an error with -Werror builds. This is problematic for FreeBSD builds. Switching to C11 allows the compatibility without the unnecessary pedantic warning. The alternative would be to clutter the support header with a `pragma clang diagnostic ignore`. GCC 4.8+ and the supported clang revisions along with MSVC support enough of C11 to allow building the builtins in C11 mode.

The atomic builtin source is problematic when cross-compiling builtins because it requires a variable and sometimes large set of system headers. This option allows users to optionally prevent it from being built. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@280416 91177308-0d34-0410-b5e6-96231b3b80d8
2016-08-23[builtins] Don't always use -ffreestanding when compiling builtinsFrancis Ricci
This can break on some sysroots. Let the user define it if necessary. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@279496 91177308-0d34-0410-b5e6-96231b3b80d8
2016-08-22[compiler-rt] Use flags found when configuring builtins during compilationFrancis Ricci
Summary: This fixes the omission of -fPIC when building the builtins. Reviewers: compnerd, beanz Subscribers: dberris, llvm-commits Differential Revision: https://reviews.llvm.org/D23729 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@279469 91177308-0d34-0410-b5e6-96231b3b80d8
2016-08-15[CMake] Renaming test variable to be consistentChris Bieneman
Based on post-commit review by compnerd. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@278728 91177308-0d34-0410-b5e6-96231b3b80d8
2016-08-12[CMake] If the compiler supports _Atomic include atomic.c in builtins librariesChris Bieneman
This fixes a long-standing TODO by implementing a compiler check for supporting the _Atomic keyword. If the _Atomic keyword is supported by the compiler we should include it in the builtin library sources. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@278454 91177308-0d34-0410-b5e6-96231b3b80d8
2016-08-05builtins: better categorisation of Thumb1 builtinsSaleem Abdulrasool
Adjust the builtins to better annotate the Thumb1 routines and their purpose. Exclude the remaining thumb1 sources on Windows ARM. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@277828 91177308-0d34-0410-b5e6-96231b3b80d8
2016-08-04builtins: split out the EABI and VFP ARM sourcesSaleem Abdulrasool
These are meant to only be included on certain targets. This only disables it for Windows ARM for now. Ideally these would be conditionally included as appropriate. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@277777 91177308-0d34-0410-b5e6-96231b3b80d8
