The branch stable/12 has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=9d8607fa3fab125d8df01e4940613beeb0f6cd38 commit 9d8607fa3fab125d8df01e4940613beeb0f6cd38 Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2021-09-25 18:24:35 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2023-03-22 22:21:30 +0000 kernel: Disable errors for -Walloca-larger-than for GCC. GCC complains about the use of alloca() with variable sizes (for XSAVE state len) in sendsig() for i386. Modern XSAVE state is probably getting a bit large for the i386 kstack, but downgrade the error to a warning.
