* Move all sources from the llvm project into contrib/llvm-project.Dimitry Andric2019-12-209508-0/+0
| | | | | | | | | | | | | This uses the new layout of the upstream repository, which was recently migrated to GitHub, and converted into a "monorepo". That is, most of the earlier separate sub-projects with their own branches and tags were consolidated into one top-level directory, and are now branched and tagged together. Updating the vendor area to match this layout is next. Notes: svn path=/head/; revision=355940
* Fix LLVM libunwnwind _Unwind_Backtrace symbol version for ARM.Michal Meloun2019-12-161-2/+2
| | | | | | | | | | | | | | | | | In original GNU libgcc, _Unwind_Backtrace is published with GCC_3.3 version for all architectures but ARM. For ARM should be publishes with GCC_4.3.0 version. This was originally omitted in r255095, fixed in r318024 and omitted aging in LLVM libunwind implementation in r354347. For ARM _Unwind_Backtrace should be published as default with GCC_4.3.0 version , (because this is right original version) and again as normal(not-default) with GCC_3.3 version (to maintain ABI compatibility compiled/linked with wrong pre r318024 libgcc) PR: 233664 Notes: svn path=/head/; revision=355803

| | | | | | | | | | | | | | | | | | | | | | | | | [PowerPC] Fix crash in peephole optimization When converting reg+reg shifts to reg+imm rotates, we neglect to consider the CodeGenOnly versions of the 32-bit shift mnemonics. This means we produce a rotate with missing operands which causes a crash. Committing this fix without review since it is non-controversial that the list of mnemonics to consider should include the 64-bit aliases for the exact mnemonics. Fixes PR44183. This should fix "Assertion failed: (idx < size()), function operator[], file /usr/src/contrib/llvm/include/llvm/ADT/SmallVector.h, line 153" when building the graphics/mesa-dri port for the PowerPC64 ELFv2 ABI.

* auditd(8): fix long-standing uninitialized memory use bugConrad Meyer2019-11-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bogus use could lead to an infinite loop depending on how fast the audit_warn script to execute. By fixing read(2) interruptibility, d060887 (r335899) revealed another bug in auditd_wait_for_events. When read is interrupted by SIGCHLD, auditd_reap_children will always return with errno set to ECHILD. But auditd_wait_for_events checks errno after that point, expecting it to be unchanged since read. As a result, it calls auditd_handle_trigger with bogus stack garbage. The result is the error message "Got unknown trigger 48." Fix by simply ignoring errno at that point; there's only one value it could've possibly had, thanks to the check up above. The best part is we've had a fix for this for like 18 months and just never merged it. Merge it now.

These instructions do not allow for an offset in their encoding, so in the latter case, the 0 is silently dropped. Due to how we have structured the RISCVAsmParser, the easiest way to add support for parsing this offset is to add a custom AsmOperand and parser. This parser drops all the parens, and just keeps the register. This commit also adds a custom printer for these operands, which matches the GCC canonical printer, printing both `(a0)` and `0(a0)` as `(a0)`.

It is necessary to generate fixups in .debug_frame or .eh_frame as relaxation is enabled due to the address delta may be changed after relaxation. There is an opcode with 6-bits data in debug frame encoding. So, we also need 6-bits fixup types. Differential Revision: https://reviews.llvm.org/D58335 llvm-svn: 366524 Merge commit f596f4507 from llvm git (by Hsiangkai Wang): [DebugInfo] Some fields do not need relocations even relax is enabled. In debug frame information, some fields, e.g., Length in CIE/FDE and Offset in FDE are attributes to describe the structure of CIE/FDE. They are not related to the relaxed code. However, these attributes are symbol differences. So, in current design, these attributes will be filled as zero and LLVM generates relocations for them. We only need to generate relocations for symbols in executable sections. So, if the symbols are not located in executable sections, we still evaluate their values under relaxation. Differential Revision: https://reviews.llvm.org/D61584 llvm-svn: 366531 Merge commit f596f4507 from llvm git (by Alex Bradbury): [RISCV] Don't force absolute FK_Data_X fixups to relocs The current behavior of shouldForceRelocation forces relocations for the majority of fixups when relaxation is enabled. This makes sense for fixups which incorporate symbols but is unnecessary for simple data fixups where the fixup target is already resolved to an absolute value. Differential Revision: https://reviews.llvm.org/D63404 Patch by Edward Jones. llvm-svn: 369257 Merge commit f596f4507 from llvm git (by Alex Bradbury): [RISCV] Implement getExprForFDESymbol to ensure RISCV_32_PCREL is used for the FDE location Follow binutils in using RISCV_32_PCREL for the FDE initial location. As explained in the relevant binutils commit <https://github.com/riscv/riscv-binutils-gdb/commit/a6cbf936e3dce68114d28cdf60d510a3f78a6d40>, the ADD/SUB pair of relocations is problematic in the presence of linker relaxation. This patch has the same end goal as D64715 but includes test changes and avoids adding a new global VariantKind to MCExpr.h (preferring RISCVMCExpr VKs like the rest of the RISC-V backend). Differential Revision: https://reviews.llvm.org/D66419 llvm-svn: 369375 This series of merges will permit riscv64 kernels and riscv64sf worlds to build with clang instead of gcc (but still using the bfd linker).

Note there are no programs in the FreeBSD base system that use std::poisson_distribution, so this is only a possible issue for ports and external programs which have been built against libc++. Therefore, I am bumping __FreeBSD_version for the benefit of our port maintainers. Requested by: emaste Security: potential OOB read MFC after: 3 days Notes: svn path=/head/; revision=354460

This should fix 'Assertion failed: (isSimple() && "Expected a SimpleValueType!")' when building the security/openssl111 port targeting a CPU that supports AVX, but not AVX2, such as sandybridge.

It causes surprising differences between platforms, such as the PR below. Prior to this change, FreeBSD inherited the default implementation of the method from the Gnu.h Generic_Elf => Generic_GCC parent class, which returned true only for amd64 targets. Override that and opt on always, similar to, e.g., NetBSD.
