When the source or destination is a register, the address size override doesn't apply. We were accidentally applying it on all sources regardless of type which was causing us to zero extend on operations that aren't affected by address size override. This fixes the OpenSSL cert error in every application, but most importantly Steam.
FEX Unit tests
FEX has its own test suite for x86-64 emulation, and we also use gcc's target tests, posixtest, and gvisor's tests. We use a combination of CMake/CTest and python runner scripts.
We also regularly run and pass qemu's and valgrind's tests for validation, but those aren't in CI right now.
x86/64 testing
- A lot of handwritten assembly unit tests in 32Bit_ASM and ASM folders, run via our TestHarnessHelper
- A few handwritten IR tests in IR, run via our IRLoader
- gcc-target-tests-32 and gcc-target-tests-64, run via FEXLoader. The tests binaries are in External/fex-gcc-target-tests-bins
Syscall testing
- 64-bit posixtest from http://posixtest.sourceforge.net/, run via FEXLoader. The tests binaries are in External/fex-posixtest-bins
- 64-bit gvisor tests from https://github.com/google/gvisor, run via FEXLoader. The tests binaries are in External/fex-gvisor-tests-bins
