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. Differential Revision: https://reviews.llvm.org/D21313 This should fix assertion failures when building OpenCV >= 3.1. PR: 215649 MFC r312831: Revert r312765 for now, since it causes assertions when building lang/spidermonkey24. 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.

Reviewed by: emaste, dim Approved by: emaste Differential Revision: https://reviews.freebsd.org/D10838 MFC r318884 (by emaste): lldb: map TRAP_CAP to a trace trap In the absense of a more specific handler for TRAP_CAP (generated by ENOTCAPABLE or ECAPMODE while in capability mode) treat it as a trace trap. 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. MFC r319796: Remove a few unneeded files from libllvm, libclang and liblldb. MFC r319885 (by emaste): lld: ELF: Fix ICF crash on absolute symbol relocations.

Add a check that both symbols point to sections before accessing their sections, and treat absolute symbols as equal if their values are equal.

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. MFC r321420: Add a few more object files to liblldb, which should solve errors when linking the lldb executable in some cases. In particular, when the -ffunction-sections -fdata-sections options are turned off, or ineffective. Reported by: Shawn Webb, Mark Millard MFC r321433: Cleanup stale Options.inc files from the previous libllvm build for clang 4.0.0. Otherwise, these can get included before the two newly generated ones (which are different) for clang 5.0.0. Reported by: Mark Millard MFC r321439 (by bdrewery): Move llvm Options.inc hack from r321433 for NO_CLEAN to lib/clang/libllvm. The files are only ever generated to .OBJDIR, not to WORLDTMP (as a sysroot) and are only ever included from a compilation. So using a beforebuild target here removes the file before the compilation tries to include it. 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.

LLVM's llvm-objdump is intended to be compatible with GNU objdump although it is currently missing some options and may have formatting differences.

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. Pull in r283061 from upstream clang trunk (by Hal Finkel): [PowerPC] Enable soft-float for PPC64, and +soft-float -> -hard-float Enable soft-float support on PPC64, as the backend now supports it.
