[libcxx-commits] [libcxx] [libc++][docs] Add 2024-11 LWG issue list (PR #118116)

Fri Nov 29 09:32:55 PST 2024

https://github.com/frederick-vs-ja created https://github.com/llvm/llvm-project/pull/118116

>From https://wg21.link/P3504R0.

Some are already implemented.
- LWG4084 and LWG4140 were already implemented at the initial commit.
- LWG3216 should have been implemented together with LWG3810 in 19c6958d24acf5beaba1946ad3e1e5fc538e3a2d.
- LWG4024 was implemented together with P1020R1 + P1973R1 in 9af9d39a47dc634b7de17708a4daf226ca699751.
- LWG4124 was implemented when initially implementing `zoned_time` formatters in afbfb16d294af2fd4f6fb3c37bb07b274adef8bc.
- LWG4141 can be considered implemented together with P0323R12 in e356f681f6c46ac35f933dc0cef3b25ceee8b210.
- LWG4157 was implemented together with P2167R3 in 557f7e1398e13c0957c7a0cbc013c1468f47a237.

Some are possibly implemented.
- LWG4154 was possibly implemented at the initial commit. Check needed.

Some seem nothing to do, but need additional check.
- It seems that LWG4064 and LWG4144 should be handled by compiler frontends.
- LWG4170 seems to only strengthen requirement on user codes, but we need to ensure that we don't provide any non-conforming contiguous iterator.
