Changelog

rustc (1.45.0+dfsg1+llvm-2ubuntu1) hirsute; urgency=medium

  * Merge 1.45.0 from Debian unstable. Remaining changes:
    - Use the bundled llvm to avoid having to do llvm updates in order to
      deliver rust updates
      - update debian/config.toml.in
      - update debian/control
      - update debian/copyright
      - update debian/rules
    - Build-Depend on libc6-dbg on armhf, to workaround a crash in ld.so
      during some debuginfo tests
      - update debian/control
    - Add a hack to ensure the stage0 compiler is extracted to the correct
      location
      - update debian/make_orig-stage0_tarball.sh
    - Scrub -g from CFLAGS and CXXFLAGS in order to let rustbuild control
      whether LLVM is compiled with debug symbols
      - update debian/rules
    - On i386, only build debuginfo for libstd
      - update debian/rules
    - Ignore all test failures on every architecture
      - update debian/rules
    - Version the Build-Conflict on gdb-minimal as gdb now Provides it
      - update debian/control
    - Adjust the rustc Breaks/Replaces libstd-rust-dev version to fix an
      upgrade issue
      - update debian/control
    - Adjust debian/watch to include +llvm in upstream version.
      - update debian/watch
    - Add Build-Depends-Indep: libssl-dev
    - Revert workaround for upstream bug #74786
    - Disable wasm build as build dependencies not currently available in
      Ubuntu.
  * Dropped change, patches no longer apply and riscv64 build fails
    anyway:
    - riscv64 support patches which no longer completely work:
      - Add more rustc patches from Debian.
      - Apply relevant llvm-toolchain-9 patches to the embedded llvm.
      - Avoid the LDFLAGS -latomic hacks from llvm-toolchain-9:
        - debian/patches/riscv64-atomic-fixes.patch: Fix libatomic detection for
        riscv64.
        - debian/patches/dsymutil-atomic.patch: Link dsymutil with -latomic.
  * Dropped change, upstream now includes LLVM with the fix:
    - Backport patch fixing miscompliation and subsequent crash on s390x
      (adapted from https://src.fedoraproject.org/rpms/llvm/pull-request/49):
      - add debian/patches/0001-InstCombine-Fix-big-endian-miscompile-of-bitcast-zex.patch
      - update debian/patches/series
