Subject: [PATCH v4 0/3] c++: Track lifetimes in constant evaluation [PR70331, ...]
Date: Thu, 20 Jul 2023 19:33:40 +1000 [thread overview]
Message-ID: <ZLj/dOJSQA37eKUE@Thaum.localdomain> (raw)
This is an update of the patch series at
https://gcc.gnu.org/pipermail/gcc-patches/2023-July/623375.html
Changes since v3:
- Use void_node in values map to indicate out-of-lifetime instead of a separate
hash set
- Remove tracking of temporaries for loops and calls
- Fix missed checks for uses of empty classes outside lifetime and associated
test
- Add reference to PR c++/110619 for the second patch, and corresponding new
test case
Bootstrapped and regtested on x86_64-pc-linux-gnu.
