2021-01-30Rollup merge of #80886 - RalfJung:stable-raw-ref-macros, r=m-ou-seYuki Okushi-2/+2
Stabilize raw ref macros This stabilizes `raw_ref_macros` (https://github.com/rust-lang/rust/issues/73394), which is possible now that https://github.com/rust-lang/rust/issues/74355 is fixed. However, as I already said in https://github.com/rust-lang/rust/issues/73394#issuecomment-751342185, I am not particularly happy with the current names of the macros. So I propose we also change them, which means I am proposing to stabilize the following in `core::ptr`: ```rust pub macro const_addr_of($e:expr) { &raw const $e } pub macro mut_addr_of($e:expr) { &raw mut $e } ``` The macro name change means we need another round of FCP. Cc `````@rust-lang/libs````` Fixes #73394

2020-10-17Rollup merge of #77932 - ssomers:btree_cleanup_gdb, r=Mark-SimulacrumDylan DPC-1/+0
BTreeMap: improve gdb introspection of BTreeMap with ZST keys or values I accidentally pushed an earlier revision in #77788: it changes the index of tuples for BTreeSet from ""[{}]".format(i) to "key{}".format(i). Which doesn't seem to make the slightest difference on my linux box nor on CI. In fact, gdb doesn't make any distinction between "key{}" and "val{}" for a BTreeMap either, leading to confusing output if you test more. But easy to improve. r? @Mark-Simulacrum
