[LLVMdev] Testing Target Optimization via ASM Injection
...t easier to generate specific ASM test cases, which I presume must exist somewhere since similar ARM optimizations have been created/tested before.

[LLVMdev] Testing Target Optimization via ASM Injection
My name is Isaac. I emailed this mailing list a couple years ago because I was working on an ARM specific target optimization for my thesis, and had questions about moving instructions and properly migrating kill flags. I have managed to get that working properly, and I now have a complete optimization that I wish to test. My question is simply this: Is there any established way to inject ARM

[LLVMdev] Question About Target Dependent Optimization
My name is Isaac. I'm a student at Cal Poly State University, San Luis Obispo, and I'm currently finishing my thesis on target-specific code optimization for my master's degree. I was wondering if I could ask a few questions I have about working with the LLVM codebase. My thesis involves optimizing the way that LLVM deals with memory operations when targeting the ARM processor
