...ther question I have is regarding register pressure estimates. I was wondering how to go about tracking the number of registers available on a target. The current schedulers (as of LLVM 2.8) use getRegPressureLimit(), but from what I can see the limits are rather rough - e.g. x86 gives a limit of 4 GP32 registers (presumably E[ABCD]X), even though, to the best of my knowledge, there are more generally available for allocation (e.g. SI, DI). It is also only taking the "top" register classes into account (e.g. counting a usage of AL and AH as two 32-bit registers). Are we interpreting thes...

...compiler technology and see this project as a great opportunity to gain experience in this field. I have taken a compiler building class and plan to focus my future studies in this area. Emulation is another area i'm interested in. I wrote a Game Boy Advance emulator in C from scratch and a GP32 emulator based on QEMU (also C). While doing this I gained a basic understanding of the QEMU codebase. I'm currently involved in a university project which develops a testing tool for glass box tests for Java and COBOL, which allows to gather certain coverage metrics, and which will be opens...
