From 12fea8644023492e93094e3d132ff244c8af439f Mon Sep 17 00:00:00 2001 From: PurHur Date: Tue, 19 May 2026 10:15:55 +0000 Subject: [PATCH] Fix AOT JUMPIF codegen and add web POST PHPT coverage Emit conditional branches on the predecessor block before compiling if/else targets so LLVM modules verify. Map REQUEST_BODY to compile -p in AotTest, add web_post.phpt, and fix boxed === null strcmp typing.
