The mergeinfo confuses Subversion enormously, and these directories will just use the mergeinfo for llvm itself. MFC r312765: Pull in r276136 from upstream llvm trunk (by Wei Mi): Use ValueOffsetPair to enhance value reuse during SCEV expansion. In D12090, the ExprValueMap was added to reuse existing value during SCEV expansion. However, const folding and sext/zext distribution can make the reuse still difficult. A simplified case is: suppose we know S1 expands to V1 in ExprValueMap, and S1 = S2 + C_a S3 = S2 + C_b where C_a and C_b are different SCEVConstants. Then we'd like to expand S3 as V1 - C_a + C_b instead of expanding S2 literally. It is helpful when S2 is a complex SCEV expr and S2 has no entry in ExprValueMap, which is usually caused by the fact that S3 is generated from S1 after const folding. In order to do that, we represent ExprValueMap as a mapping from SCEV to ValueOffsetPair. We will save both S1->{V1, 0} and S2->{V1, C_a} into the ExprValueMap when we create SCEV for V1. When S3 is expanded, it will first expand S2 to V1 - C_a because of S2->{V1, C_a} in the map, then expand S3 to V1 - C_a + C_b.

Reported by: antoine PR: 215649 MFC r316511 (by jhb): Add an implementation of __ffssi2() derived from __ffsdi2(). Newer versions of GCC include an __ffssi2() symbol in libgcc and the compiler can emit calls to it in generated code. This is true for at least GCC 6.2 when compiling world for mips and mips64.

Example usage (testing the bug in PR219173): % proccontrol -m trapcap lldb usr.bin/hexdump/obj/hexdump -- -Cv -s 1 /bin/ls ...

In the future we should have LLDB control the trapcap procctl itself (as it does with ASLR), as well as report a specific stop reason. This change eliminates an assertion failure from LLDB for now.

Upstream has branched for the 5.0.0 release, which should be in about a month. Please report bugs and regressions, so we can get them into the release. Please note that from 3.5.0 onwards, clang, llvm and lldb require C++11 support to build; see UPDATING for more information.

The files are only ever generated to .OBJDIR, not to WORLDTMP (as a sysroot) and are only ever included from a compilation.

MFC r321664: Pull in r308891 from upstream llvm trunk (by Benjamin Kramer): [CodeGenPrepare] Cut off FindAllMemoryUses if there are too many uses. This avoids excessive compile time. The case I'm looking at is Function.cpp from an old version of LLVM that still had the giant memcmp string matcher in it. Before r308322 this compiled in about 2 minutes, after it, clang takes infinite* time to compile it. With this patch we're at 5 min, which is still bad but this is a pathological case. The cut off at 20 uses was chosen by looking at other cut-offs in LLVM for user scanning. It's probably too high, but does the job and is very unlikely to regress anything. Fixes PR33900. * I'm impatient and aborted after 15 minutes, on the bug report it was killed after 2h. Pull in r308986 from upstream llvm trunk (by Simon Pilgrim): [X86][CGP] Reduce memcmp() expansion to 2 load pairs (PR33914) D35067/rL308322 attempted to support up to 4 load pairs for memcmp inlining which resulted in regressions for some optimized libc memcmp implementations (PR33914). Until we can match these more optimal cases, this patch reduces the memcmp expansion to a maximum of 2 load pairs (which matches what we do for -Os). This patch should be considered for the 5.0.0 release branch as well Differential Revision: https://reviews.llvm.org/D35830 These fix a hang (or extremely long compile time) when building older LLVM ports.

Differential Revision: https://reviews.llvm.org/D24466 Reported by: Mark Millard PR: 214433 MFC r309149: Pull in r283060 from upstream llvm trunk (by Hal Finkel): [PowerPC] Refactor soft-float support, and enable PPC64 soft float This change enables soft-float for PowerPC64, and also makes soft-float disable all vector instruction sets for both 32-bit and 64-bit modes. This latter part is necessary because the PPC backend canonicalizes many Altivec vector types to floating-point types, and so soft-float breaks scalarization support for many operations. Both for embedded targets and for operating-system kernels desiring soft-float support, it seems reasonable that disabling hardware floating-point also disables vector instructions (embedded targets without hardware floating point support are unlikely to have Altivec, etc. and operating system kernels desiring not to use floating-point registers to lower syscall cost are unlikely to want to use vector registers either). If someone needs this to work, we'll need to change the fact that we promote many Altivec operations to act on v4f32. To make it possible to disable Altivec when soft-float is enabled, hardware floating-point support needs to be expressed as a positive feature, like the others, and not a negative feature, because target features cannot have dependencies on the disabling of some other feature. So +soft-float has now become -hard-float. Fixes PR26970.

This is an optional coprocessors may not be present in all devices, however it appears to be in all current SoCs we support. armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too old to support this. Because of this there are a number of WITH/WITHOUT options that are unsupported and must be left as the default value. The options and their required value are: * WITH_ARM_EABI * WITHOUT_GCC * WITHOUT_GNUCXX In addition, without an external toolchain, the following need to be left as their default: * WITH_CLANG * WITH_CLANG_IS_CC As there is a different method of passing float and double values to functions the ABI is incompatible with existing armv6 binaries. To use this a full rebuild of world is required. Because no floating point values are passed into the kernel an armv6 kernel with VFP enabled will work with an armv6hf userland and vice versa.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clang only supports atomic operations for ARMv6. For non-ARMv6, we still need to emit these functions. Clang's prototype for these functions slightly differs, as it is truly based on GCC's documentation. It requires the use of signed types, but also requires varargs. Still, we are not allowed to simply implement this function directly. Cleverly work around this by implementing it under a different name and using __strong_reference().

| |/ |/| | | | | | | | | | | | | | | Originally we disabled libcompiler-rt on MIPS and SPARC64, because of an issue where __clzdi2 and __ctzdi2 would cause endless recursion. This bug has been fixed in r230021 already, but for some reason we only switched to libcompiler-rt on SPARC64 -- not MIPS. This means we can finally use <stdatomic.h> on all our architectures.
