[docs] Remove hard-coded version numbers from sphinx configs This updates all the non-runtime project release notes to use the version number from CMake instead of the hard-coded version numbers in conf.py. It also hides warnings about pre-releases when the git suffix is dropped from the LLVM version in CMake. Reviewed By: MaskRay Differential Revision: https://reviews.llvm.org/D112181

=================================================
ELF Improvements
----------------
[ELF] Add convenience TableGen classes to enforce two dashes for options not supported by GNU ld Announced on https://lists.llvm.org/pipermail/llvm-dev/2020-May/141416.html For many options, we have to support either one or two dash to be compatible with GNU ld. For newer and lld specific options, we can enforce strict double dashes. Affected options: * --thinlto-* * --lto-* * --shuffle-sections= This patch does not change `-plugin-opt=*` because clang driver passes `-plugin-opt=*` and I don't intend to cause churn. In 2000, GNU ld tried something similar with --omagic https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=e4897a3288f37d5f69e8acd256a6e83e607fe8d8 Reviewed By: tejohnson, psmith Differential Revision: https://reviews.llvm.org/D79371

[WebAssembly] Initial support for shared objects (-shared) Based on the initial spec proposal: https://github.com/WebAssembly/tool-conventions/blob/master/DynamicLinking.md The llvm/codegen side of this is still missing but I believe this change is still worth landing as an incremental step Differential Revision: https://reviews.llvm.org/D54249 llvm-svn: 346918

WebAssembly Improvements
------------------------
[LLD][ARM] Handle .ARM.exidx sections at non-zero output sec offset Embedded systems that do not use an ELF loader locate the .ARM.exidx exception table via linker defined __exidx_start and __exidx_end rather than use the PT_ARM_EXIDX program header. This means that some linker scripts such as the picolibc C library's linker script, do not have the .ARM.exidx sections at offset 0 in the OutputSection. For example: .except_unordered : { . = ALIGN(8); PROVIDE(__exidx_start = .); *(.ARM.exidx*) PROVIDE(__exidx_end = .); } >flash AT>flash :text This is within the specification of Arm exception tables, and is handled correctly by ld.bfd. This patch has 2 parts. The first updates the writing of the data of the .ARM.exidx SyntheticSection to account for a non-zero OutputSection offset. The second part makes the PT_ARM_EXIDX program header generation a special case so that it covers only the SyntheticSection and not the parent OutputSection. While not strictly necessary for programs locating the exception tables via the symbols it may cause ELF utilities that locate the exception tables via the PT_ARM_EXIDX program header to fail. This does not seem to be the case for GNU and LLVM readelf which seems to look for the SHT_ARM_EXIDX section. Differential Revision: https://reviews.llvm.org/D148033
