Ryan Houdek 921867de7e Works around Clang failing to identify new Kryo CPUs 
Some of the newer CPU cores in LLVM's source claim to be a Cortex-A73,
which means they become limited to an ARMv8.0 feature set.

This is what you get if you compile FEX with -mcpu=native

To work around this issue, manually parse /proc/cpuinfo ourselves and
pull out the CPU type to pass to clang directly.
This also fixes the issue that we were using -march on AArch64, which no
longer works on newer clang versions. We instead need to use mcpu or
mtune.

Should improve all atomic op performance outside of the JITs, where they
were turning in to loadstore exclusive pairs.

Ryan Houdek 544a1f307f Adds an option to disable optimization passes 
Instead of forcing someone to test by modifying code, allow a -O0 option
to be passed in.
Also added to FEXConfig GUI for easily touching.

Fixes #652

Ryan Houdek 1084ecf2d3 Fixes more 16bit modrm addressing problems 
In the case of an instruction that used 16bit addressing mode. It would
calculate the amount of displacement needing to be read using a 32bit
modrm mode. It would then read calculate modrm displacement again and
read the correct number of bytes.

Leftover bytes would then be in a mismatched state which means if an
instruction was using 16bit addressing + modrm + literal at /that/ point
the number of literal bytes remaining would be calculated as a negative.

This didn't actually break things since instructions that have modrm +
literal and can safely use 16bit addressing without breaking in a 32bit
environment is impossible on Linux. Due to the inability to map a memory
range in 16bit range.

Disables killpg tests and reenables a few tests
 2021-01-11 19:32:35 +02:00
Ryan Houdek b857d6ba16 Disables killpg tests and reenables a few tests 
killpg has been causing us testing problems for a while now.
As we were running more tests it was becoming more likely to hit a test
doing killpg in the background.

All of the tests run under the same process group so it is a significant
race condition to have these running.
Until we improve CI to somehow work around how killpg works, we just
need to have these disabled.
