From 4f206ac1ea1b20400fa242f2f3be86237c4ba3bf Mon Sep 17 00:00:00 2001 From: Nihal Jere Date: Sat, 27 Apr 2024 14:47:15 -0700 Subject: Implement variable length arrays Variably modified types are required for C23. Since QBE doesn't currently support saving and restoring the stack pointer, a current limitation is that we can't reclaim stack space from VLAs that go out of scope. This is potentially problematic for VLAs appearing in a loop, but this case is uncommon enough that it is silently ignored for now.
