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.
…workingjubilee Describe and use CStr literals in CStr and CString docs Mention CStr literals in the description of both types, and use them in some of the code samples for CStr. This is intended to make C string literals more discoverable. Additionally, I don't think the orange "This example is not tested" warnings are very encouraging, so I have made the examples on `CStr` build.
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)

… r=compiler-errors `rustc_expand` cleanups Some cleanups I made while looking through this code. Nothing that requires any real domain-specific knowledge about this crate. r? `@michaelwoerister`
variable-precision float operations can differ depending on optimization levels Follow-up to rust-lang#121793 and rust-lang#118217 that accounts for optimizations changing the precision of these functions. Fixes rust-lang#109118 Fixes rust-lang#71355
