From 20ebc7ea8209cb8f1ff3916706b6e7d8232c9f3f Mon Sep 17 00:00:00 2001 From: Shubham Sandeep Rastogi Date: Sat, 22 Nov 2025 00:49:35 -0800 Subject: Add new llvm.dbg.declare_value intrinsic. (#168132) For swift async code, we need to use a debug intrinsic that behaves like an llvm.dbg.declare but can take any location type rather than just a pointer or integer. To solve this, a new debug instrinsic called llvm.dbg.declare_value has been created, which behaves exactly like an llvm.dbg.declare but can take non pointer and integer location types.
