Pull Request Overview
This PR extends the GlobalDepsAnalyzer to lower additional overflow intrinsics by implementing manual overflow detection for signed arithmetic operations. The change allows these intrinsics to be replaced with explicit arithmetic and comparison operations when compiling with the LLC pass.
- Added lowering support for
sadd_with_overflowandssub_with_overflowintrinsics using bit manipulation techniques - Added lowering support for
smul_with_overflowintrinsic using division-based overflow detection - Fixed missing
continuestatements in existing overflow intrinsic handlers
