Subject: [PATCH] Let LLVM 5 add DW_OP_deref to indirect args itself
We needed to manually added the `DW_OP_deref` ourselves in earlier LLVM,
but starting with [D31439] in LLVM 5, it appears that LLVM will always
handle this itself. When we were still adding this manually, the
resulting `.debug_loc` had too many derefs, and this failed test
`debuginfo/by-value-self-argument-in-trait-impl.rs`.
[D31439]: https://reviews.llvm.org/D31439
Fixes #47611.

Subject: [PATCH] Update DW_OP_plus to DW_OP_plus_uconst
LLVM <= 4.0 used a non-standard interpretation of `DW_OP_plus`. In the
DWARF standard, this adds two items on the expressions stack. LLVM's
behavior was more like DWARF's `DW_OP_plus_uconst` -- adding a constant
that follows the op. The patch series starting with [D33892] switched
to the standard DWARF interpretation, so we need to follow.

From 36fcfd117373283de7c052cf361a705d611d47fa Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/2] Use a range to identify SIGSEGV in stack guards
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Previously, the `guard::init()` and `guard::current()` functions were
returning a `usize` address representing the top of the stack guard,
respectively for the main thread and for spawned threads. The `SIGSEGV`
handler on `unix` targets checked if a fault was within one page below
that address, if so reporting it as a stack overflow.
Now `unix` targets report a `Range<usize>` representing the guard
memory, so it can cover arbitrary guard sizes. Non-`unix` targets which
always return `None` for guards now do so with `Option<!>`, so they
don't pay any overhead.
For `linux-gnu` in particular, the previous guard upper-bound was
`stackaddr + guardsize`, as the protected memory was *inside* the stack.
This was a glibc bug, and starting from 2.27 they are moving the guard
*past* the end of the stack. However, there's no simple way for us to
know where the guard page actually lies, so now we declare it as the
whole range of `stackaddr ± guardsize`, and any fault therein will be
called a stack overflow. This fixes #47863.
