* Move all sources from the llvm project into contrib/llvm-project.Dimitry Andric2019-12-20105-40427/+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

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.

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).

* clang: Enable unwind tables on !amd64Conrad Meyer2019-11-062-0/+3
| | | | | | | | | | | | | | | | | | | | | | There doesn't seem to be much sense in defaulting "on" unwind tables on amd64 and not on other arches. 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.

* Pull in r372186 from upstream llvm trunk (by Eli Friedman):Dimitry Andric2019-10-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ARM] VFPv2 only supports 16 D registers. r361845 changed the way we handle "D16" vs. "D32" targets; there used to be a negative "d16" which removed instructions from the instruction set, and now there's a "d32" feature which adds instructions to the instruction set. This is good, but there was an oversight in the implementation: the behavior of VFPv2 was changed. In particular, the "vfp2" feature was changed to imply "d32". This is wrong: VFPv2 only supports 16 D registers. In practice, this means if you specify -mfpu=vfpv2, the compiler will generate illegal instructions. This patch gets rid of "vfp2d16" and "vfp2d16sp", and fixes "vfp2" and "vfp2sp" so they don't imply "d32".

| | | | | | | | | | | | | | | | | change https://reviews.llvm.org/rL356631 ("[X86] Add CMPXCHG8B feature flag. Set it for all CPUs except i386/i486 including 'generic'. Disable use of CMPXCHG8B when this flag isn't set"), clang now correctly emits calls to __atomic_load_8, __atomic_store_8, etc. when targeting i486, and this means we can no longer link most modern programs, because we do not have a libatomic, nor support for atomic functions in libc. See also PR 230888, 220822, 233725, 234976, and more probably duplicates. Note that in practice, clang has been incorrectly generating cmpxchg8b instructions for years now, when targeting i486.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FreeBSD previously defaulted to DWARF 2 because several tools (gdb, ctfconvert, etc.) did not support later versions. These have either been fixed or are deprecated. Note that gdb 6 still exists but has been moved out of $PATH into /usr/libexec and is intended only for use by crashinfo(8). The kernel build sets the DWARF version explicitly via -gdwarf2, so this should have no effect there.
