a4e85ad565 emit_x64: Make RSB a stack 2020-04-22 20:26:40 +01:00

2a818f9d8e Merge branch 'timing' 
We do this to improve timing information before entering a supervior
function. We also do this to try and stay within JITted code as much
as possible, by updating the cycles we have remaining.

814e378249 VCMP and VCMPE were the other way around 
- This was due to a misunderstanding of what the E in VCMPE means.
- The E refers to an exception being raised when a QNaN is encountered.
- Added unit tests for VCMP{E}

08f638d447 emit_x64: pmaxuw and pminuw require SSE 4.1 
This commit is intended to close citra-emu/citra#3137.

pmaxuw and pminuw were used to perform unsigned comparisons; we emulate
these using a signed comparison by offsetting the inputs by 0x8000 for
CPUs that do not support SSE 4.1.

9ac890c62d reg_alloc: Fix for LLVM's interpretation of the System V ABI 
This aspect of the System V ABI is under-defined. LLVM choses a
different interpretation from GCC and ICC.

Most other compilers assume the callee is responsible zero-ing the
upper bits of the register if necessary. LLVM assumes the caller
has zero-extended the register.

This is a quick fix for this problem until zext-tracking is
implemented.
