Description

Problem

Goal: Get the PowerPC tests to succeed on Linux hosts.

As of now, a bunch of posix functionality is stubbed out in xenia-base. You can fill in functionality as it's needed for the tests.

Code for posix functionality can be found in src/xenia/base/*_posix.cc Code for the tester lives in ppc_testing_main.cc

Some useful commands can be found in .travis.yml for building/setup on Linux hosts.

Task List

  • - Mapped memory support on Linux (mapped_memory_posix.cc)
    • At the moment, the tester cannot allocate memory to store generated code.

Research direction
Implement the missing POSIX functions in src/xenia/base/mapped memory posix.cc for memory mapping on Linux. Refer to the existing Windows implementation and POSIX documentation. Use the .travis.yml for build instructions. After implementation, run the PowerPC tests to verify success.
