Git commit 69685bb9ce2dc1976b9f4f852caaebdfd98485d1 by GitHub (on behalf of Louis Dionne) on 31/07/2026 at 17:20..
[libc++] Actually partially populate the container in a benchmark (#213146)

The "partially populated" variant of assignment was a copy-paste of the
"into cleared container" assignment.

Git commit dac66ca4776b18304249bb3a37f08915e5ad1bf4 by GitHub (on behalf of Louis Dionne) on 31/07/2026 at 17:21..
[libc++] Fix dangling reference in the associative container benchmarks (#213139)

Two insert benchmarks were registered with lambdas capturing insert_iter_iter_bench
by reference, unlike every other registration in this file, which captures by value.

RegisterBenchmark() stores the lambda by value and only invokes it from
RunSpecifiedBenchmarks(), which happens long after associative_container_benchmarks()
has returned, creating a dangling reference.

Git commit 194d7d819f3ccf15c836323bc0efa34920045c0d by GitHub (on behalf of Timm Baeder) on 31/07/2026 at 17:21..
[llvm] Include ArrayRef.h in GenericCycleInfo.h (#213267)

Try to fix the llvm-x86_64-debian-dylib builder, which has been broken
for a while with:

I'm not sure if this will help or not, I can't reproduce this locally
and nobody else seems to have the same problem(?).

Git commit 9bc2dd1a7015b58c9c68e8174e5d2756d955c0ca by GitHub (on behalf of Louis Dionne) on 31/07/2026 at 17:21..
[libc++] Add an assertion for monotonic_buffer_resource's initial_size (#213136)

[mem.res.monotonic.buffer.ctor] requires initial_size to be greater than
zero for the two constructors that take one, but we silently accepted
zero. Add a hardening assertion for that precondition.

Fixes #213059

Git commit c433135c99fc3306ae93fa8cff9e5c00ad0ece3c by GitHub (on behalf of Louis Dionne) on 31/07/2026 at 17:25..
[libc++] Remove unused headers from <cmath> (#213114)

I believe these headers were relevant when we actually implemented
functions in `<cmath>`, but they are not anymore. Note that ::hypot in
particular is obtained from <math.h> like all the other math functions.
