* Move all sources from the llvm project into contrib/llvm-project.Dimitry Andric2019-12-2027-16151/+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. 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).

* 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". Differential Revision: https://reviews.llvm.org/D67375 Pull in r372187 from upstream clang trunk (by Eli Friedman): [ARM] Update clang for removal of vfp2d16 and vfp2d16sp Matching fix for https://reviews.llvm.org/D67375 (r372186).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't treat .symver as a regular alias definition. This patch starts simplifying the handling of .symver. For now it just moves the responsibility for creating an alias down to the streamer. With that the asm streamer can pass a .symver unchanged, which is nice since gas cannot parse "foo@bar = zed". In a followup I hope to move the handling down to the writer so that we don't need special hacks for avoiding breaking names with @@@ on windows. Pull in r327160 from upstream llvm trunk (by Rafael Espindola): Delay creating an alias for @@@. With this we only create an alias for @@@ once we know if it should use @ or @@. This avoids last minutes renames and hacks to handle MS names. This only handles the ELF writer. LTO still has issues with @@@ aliases.
