Hi list, This series implements support for 32-bit GPU pointers which reduces the number of user SGPRs that are needed for binding descriptors.
There is no CTS regressions and all games seem to get a minor performance boost (tested on Polaris/Vega). If you want to test or run some benchmarks yourself, please note that LLVM 7.0 is required. Please review, Thanks!
