- Update to 1.11.0:
  * Big news:
    - Frontend, druntime and Phobos are at version 2.081.2. 
      (#2752, #2772, #2776, #2791, #2815) (new)
    - Add some support for classes without TypeInfos, for 
      -betterC and/or a minimal (d)runtime. (#2765)
    - LLVM for prebuilt packages upgraded to v6.0.1. 
      The x86_64 packages feature some more LLVM targets for 
      cross-compilation (experiments): MIPS, MSP430, RISC-V 
      and WebAssembly. (#2760)
    - Rudimentary support for compiling & linking directly to 
      WebAssembly. See the dedicated Wiki page for how to get 
      started. (#2766, #2779, #2785)
    - AArch64 (64-bit ARM) now mostly working on Linux/glibc 
      and Android. Current ltsmaster is able to bootstrap v1.11, 
      which can also bootstrap itself; most tests pass. 
      (Preliminary) CI has been set up. (#2802, #2817, #2813) (new)
    - LDC on Windows now uses 80-bit compile-time reals. This allows 
      for seamless cross-compilation to other x86(_64) targets, 
      e.g., without real.min underflowing to 0 and real.max 
      overflowing to infinity. (#2752)
    - New @naked UDA in ldc.attributes & enhanced functionality 
      for @llvmAttr("<name>"). (#2773) 
  * Platform support:
    - Supports LLVM 3.7 - 6.0.
    - Windows: Supports Visual Studio/C++ Build Tools 2015 and 2017.
    - Alpine linux/x64: built against Musl libc to support Docker 
      images based on the Alpine distro, requires the llvm5-libs, 
      musl-dev, and gcc packages to build and link D apps and the 
      tzdata and libcurl packages for certain stdlib modules.
  * Bug fixes:
    - extern(C++) on Posix: Pass non-PODs indirectly by value. 
      (#2728)
    - extern(C++) on Windows/MSVC: Methods return all structs via 
      hidden sret pointer. (#2720, #1935)
    - Make GC2Stack IR optimization pass work as intended. (#2750)
    - Work around inline assembly regression with LLVM 6 on Win32. 
      The prebuilt Win32 package is now using LLVM 6.0.1 too. (#2629, #2770)
    - Fix overzealous check for multiple main() functions. (#2778) (new)
    - Fix corrupt prefix in integrated LLD's console output. (#2781) (new)
    - No context ptr for nested non-extern(D) functions. (#2808, #2809) (new)
  * Known issues:
    - LDC does not zero the padding area of a real variable. This may
      lead to wrong results if the padding area is also considered. 
      See #770. Does not apply to real members inside structs etc.
- Update bootstrap version to 0.17.6:
  * Added support for LLVM 6.0 and 7.0. (#2600, #2825)
  * Backported AArch64 fixes from master; most tests passing on 
    Linux/glibc and Android
  * Fix generation of debug info. (#2594)
  * Added support for bootstrapping on DragonFly BSD
  * Fixed missing definition in std.datetime on Solaris
  * Fixed std.datetime unittest failure. (ldc-developers/phobos#59)
  * Fixed tests for PowerPC. (#2634, #2635)
  * Improvements for MIPS.
  * Make core.stdc.stdarg.va_* functions nothrow to enable 
    compiling the 2.082 frontend. (#2821)
  * CI updates.
- Remove upstreamed patches:
  * ldc-0.17.5-add_missing_include.patch
  * ldc-0.17.5-add_support_to_LLVM6.patch
  * ldc-0.17.5-backport_pr_2315.patch
  * ldc-0.17.5-default-to-pic.patch
- Enable aarch64 since it can be boostrapped with ldc 0.17.6
- Fix x86_64 build by adding '-fPIC' to C_FLAGS of bootstrap

From 6ed3ce435845e72ce8c88d39c0f7d3fb950ef54e Mon Sep 17 00:00:00 2001
From: Johan Engelen <jbc.engelen@gmail.com>
Date: Mon, 18 Sep 2017 23:11:32 +0200
Subject: [PATCH] Backport PR #2315.
The change is to fix debuginfo build errors with Phobos and LLVM5.0. This PR is mostly copy-pasting from master and fixing compile errors, so not much checking whether things make sense or not for LTS.

Subject: [PATCH] Default to PIC code on Linux
Modern Linux distributions have their toolchain generate PIC code for
additional security features (like ASLR).
Since there is no (sane) way to detect whether the toolchain defaults to
PIC code, we simply default to PIC code on all Linux
distributions to avoid linking issues on these OSes.
The relocation model can be switched back to non-PIC code manually at
any time.

Fri Aug 24 10:24:47 UTC 2018 - guillaume@opensuse.org
- Update to 1.11.0:
* Big news:
- Frontend, druntime and Phobos are at version 2.081.2.
(#2752, #2772, #2776, #2791, #2815) (new)
- Add some support for classes without TypeInfos, for
-betterC and/or a minimal (d)runtime. (#2765)
- LLVM for prebuilt packages upgraded to v6.0.1.
The x86_64 packages feature some more LLVM targets for
cross-compilation (experiments): MIPS, MSP430, RISC-V
and WebAssembly. (#2760)
- Rudimentary support for compiling & linking directly to
WebAssembly. See the dedicated Wiki page for how to get
started. (#2766, #2779, #2785)
- AArch64 (64-bit ARM) now mostly working on Linux/glibc
and Android. Current ltsmaster is able to bootstrap v1.11,
which can also bootstrap itself; most tests pass.
(Preliminary) CI has been set up. (#2802, #2817, #2813) (new)
- LDC on Windows now uses 80-bit compile-time reals. This allows
for seamless cross-compilation to other x86(_64) targets,
e.g., without real.min underflowing to 0 and real.max
overflowing to infinity. (#2752)
- New @naked UDA in ldc.attributes & enhanced functionality
for @llvmAttr("<name>"). (#2773)
* Platform support:
- Supports LLVM 3.7 - 6.0.
- Windows: Supports Visual Studio/C++ Build Tools 2015 and 2017.
- Alpine linux/x64: built against Musl libc to support Docker
images based on the Alpine distro, requires the llvm5-libs,
musl-dev, and gcc packages to build and link D apps and the
tzdata and libcurl packages for certain stdlib modules.
* Bug fixes:
- extern(C++) on Posix: Pass non-PODs indirectly by value.
(#2728)
- extern(C++) on Windows/MSVC: Methods return all structs via
hidden sret pointer. (#2720, #1935)
- Make GC2Stack IR optimization pass work as intended. (#2750)
- Work around inline assembly regression with LLVM 6 on Win32.
The prebuilt Win32 package is now using LLVM 6.0.1 too. (#2629, #2770)
- Fix overzealous check for multiple main() functions. (#2778) (new)
- Fix corrupt prefix in integrated LLD's console output. (#2781) (new)
- No context ptr for nested non-extern(D) functions. (#2808, #2809) (new)
* Known issues:
- LDC does not zero the padding area of a real variable. This may
lead to wrong results if the padding area is also considered.
See #770. Does not apply to real members inside structs etc.
- Update bootstrap version to 0.17.6:
* Added support for LLVM 6.0 and 7.0. (#2600, #2825)
* Backported AArch64 fixes from master; most tests passing on
Linux/glibc and Android
* Fix generation of debug info. (#2594)
* Added support for bootstrapping on DragonFly BSD
* Fixed missing definition in std.datetime on Solaris
* Fixed std.datetime unittest failure. (ldc-developers/phobos#59)
* Fixed tests for PowerPC. (#2634, #2635)
* Improvements for MIPS.
* Make core.stdc.stdarg.va_* functions nothrow to enable
compiling the 2.082 frontend. (#2821)
* CI updates.
- Remove upstreamed patches:
* ldc-0.17.5-add_missing_include.patch
* ldc-0.17.5-add_support_to_LLVM6.patch
* ldc-0.17.5-backport_pr_2315.patch
* ldc-0.17.5-default-to-pic.patch
- Enable aarch64 since it can be boostrapped with ldc 0.17.6
- Fix x86_64 build by adding '-fPIC' to C_FLAGS of bootstrap
