"is greater or equal to". Beside common sense.
library/backtrace also declares a feature called `gimli-symbolize` which appear used, but the feature in std with the same name is unused, so remove it.
`ConstKind::Value` is the only variant where control flow leaves the first match on `impl_ct.kind()`, so there is no need for a second match on the same expression later on.
Sort them, and remove the unused ones (`lint_reasons` and `proc_macro_span`).
They each have a single call site.
Control flow never gets past the end of the `ExpandResult::Retry` match arm, due to the `span_bug` and the `continue`. Therefore, the code after the match can only be reached from the `ExpandResult::Ready` arm. This commit moves that code after the match into the `ExpandResult::Ready` arm, avoiding the need for the `continue` in the `ExpandResult::Retry` arm.
Too clever by half, IMO.
Alongside the existing `Invocation::span`.
Because the type is not obvious, and this clarifies things.
It is currently an enum and the `tts` and `idx` fields are repeated across the two variants. This commit splits it into a struct `Frame` and an enum `FrameKind`, to factor out the duplication. The commit also renames `Frame::new` as `Frame::new_delimited` and adds `Frame::new_sequence`. I.e. both variants now have a constructor.
…ompiler-errors deref patterns: impl `DerefPure` for more std types Context: [deref patterns](rust-lang#87121). The requirements of `DerefPure` aren't precise yet, but these types unambiguously satisfy them. Interestingly, a hypothetical `impl DerefMut for Cow` that does a `Clone` would *not* be eligible for `DerefPure` if we allow mixing deref patterns with normal patterns. If the following is exhaustive then the `DerefMut` would cause UB: ```rust match &mut Cow::Borrowed(&()) { Cow::Owned(_) => ..., // Doesn't match deref!(_x) if false => ..., // Causes the variant to switch to `Owned` Cow::Borrowed(_) => ..., // Doesn't match // We reach unreachable } ```

…s, r=Amanieu String.truncate comment microfix (greater or equal) String.truncate calls Vec.truncate, in turn, and that states "is greater or equal to". Beside common sense.
run-make-support: preserve tooks.mk behavior for EXTRACXXFLAGS In rust-lang#123149 when trying to add a command wrapper for `cc`, I didn't preserve the behavior of tools.mk completely: tools.mk had ```makefile # Extra flags needed to compile a working executable with the standard library ifdef IS_WINDOWS ifdef IS_MSVC #EXTRACFLAGS := ws2_32.lib userenv.lib advapi32.lib bcrypt.lib ntdll.lib synchronization.lib else #EXTRACFLAGS := -lws2_32 -luserenv -lbcrypt -lntdll -lsynchronization EXTRACXXFLAGS := -lstdc++ #EXTRARSCXXFLAGS := -l static:-bundle=stdc++ endif else ifeq ($(UNAME),Darwin) #EXTRACFLAGS := -lresolv EXTRACXXFLAGS := -lc++ #EXTRARSCXXFLAGS := -lc++ else ifeq ($(UNAME),FreeBSD) #EXTRACFLAGS := -lm -lpthread -lgcc_s else ifeq ($(UNAME),SunOS) #EXTRACFLAGS := -lm -lpthread -lposix4 -lsocket -lresolv else ifeq ($(UNAME),OpenBSD) #EXTRACFLAGS := -lm -lpthread -lc++abi #RUSTC := $(RUSTC) -C linker="$(word 1,$(CC:ccache=))" else #EXTRACFLAGS := -lm -lrt -ldl -lpthread EXTRACXXFLAGS := -lstdc++ #EXTRARSCXXFLAGS := -lstdc++ endif endif endif endif endif ``` Note that for {`FreeBSD`, `SunOs`, `OpenBSD`} the `-lstdc++` flag is *not* passed, so `EXTRACXXFLAGS` for those platforms should be an empty `vec![]`. r? ghost (testing this with PR CI)
