>From c4b615bcb30f3e8e87ccbcd6ec2331067483aea3 Mon Sep 17 00:00:00 2001 From: h-vetinari <[email protected]> Date: Sat, 14 Feb 2026 09:03:41 +1100 Subject: [PATCH] [libc++] Increase the minimum deployment target on macOS to 11.0 (#176094) #166172 moved the effective minimum deployment target on macOS to 10.15 (because `aligned_alloc` is not defined before that in the C stdlib), and indeed, it was mentioned in that PR that libc++ only supports macOS 11 and later. This PR rectifies the documentation and the code to reflect the actually supported deployment targets on macOS. See [1] for additional discussion about this.
