Ryan Houdek c677fdf3e1 Adds support for the CPUBackends to run in a compile thread 
These take different paths depending on if it was for a compile thread
or not

Ryan Houdek edce88e66e Ensures that we don't try and free the Dispatcher code if it doesn't 
exist

This doesn't happen yet but it will soon

Ryan Houdek 47d47fac86 Adds function for copying data required for threaded compiler 
These structures need to be shared to the threaded compiler, so set it
up for copying.

Will be necessary for the compile service

Ryan Houdek f775bea63f Fixes cache clear bug on x86_64 
On cache clear this would munmap pages 1.5x past the code cache.
This most certainly leads to spurious bugs

Ryan Houdek c122516077 Adds resizable frontend decoded buffer 
Allows us to save memory in the frontend decoder by starting out with a
small buffer until we hit larger code blocks.

Stefanos Kornilios Mitsis Poiitidis 1ffc8c15e2 Backends: Add OP_INVALIDATEFLAGS as nop 2020-11-17 11:11:18 +02:00
Stefanos Kornilios Mitsis Poiitidis 11e12a9b36 Add --unsafe-no-pf 2020-11-17 11:11:13 +02:00
Stefanos Kornilios Mitsis Poiitidis 8fc6f73571 IR: InvalidateFlags + --abi-local-flags 
- InvalidateFlags pseudo-op is a hint for the Dead Flags Elimination pass that flags are not needed past that point
- Adds a new option, --abi-local-flags, that invalidates the flags on CALLs or RETs. This might break code that doesn't follow the ABI rules.
 2020-11-17 11:08:29 +02:00
Stefanos Kornilios Mitsis Poiitidis 2dad4718d6 IR: Add DumpIR option, --dump-ir command line 
This dumps the IR before and after optimizations

--dump-ir can be

"no" -> Do not dump
"stderr" -> Dump to stderr
"stdout" -> Dump to stdout
"some/path" -> Dump to "some/path/$GuestRip-pre.ir" and "some/path/$GuestRip-post.ir"

Ryan Houdek 34625441cb Fixes FCOMPP and FUCOMPP 
These two instructions pop the x87 stack twice which we didn't support
Repurposes the dead pop template argument to be a "pop twice".
Everything else falls down the table flag information comparison
 2020-10-27 23:09:17 -07:00
Ryan Houdek d3d57d48a0 Fixes missing pop flag in x87 table 
FCOMP didn't have POP set so it wans't popping the stack.
FFREEP also didn't have it, but it was handled explicitly in the
dispatcher

Ryan Houdek b8b99e7f85 Merge pull request #475 from Sonicadvance1/fix_32bit_x87 
Fixes 32bit x87 usage
 2020-10-25 11:21:50 -07:00
Ryan Houdek 7f4836b982 Fixes 32bit x87 usage 
All of the ops that were relying on a 64bit memory offset were being
downgraded to 32bit.

Abuses the XMM_FLAGS option a bit to indicate that it shouldn't
downgrade the 64bit size flag. Which isn't an issue since all these
operations can't encode a register since modrm_r is used for table
decoding

Stefanos Kornilios Mitsis Poiitidis 82d9b28563 Merge pull request #476 from Sonicadvance1/initial_sse4_1

Stefanos Kornilios Mitsis Poiitidis 13dc69987c Merge pull request #474 from Sonicadvance1/more_32bit_fixes_2 
More 32bit related fixes
 2020-10-25 06:40:27 +02:00
Ryan Houdek f6c2ee40d1 Adds some initial SSE 4.1 ops 
These are being used unconditionally by the steam client (browser?) and
Minit.

Push out the initial implementation without unit tests just to get
further.
Would be nice to figure out why these are using these ops instead of
checking if it is supported.
 2020-10-24 21:34:23 -07:00
Ryan Houdek c050e094da Adds four new 32bit push and pop ops 
push and pop for segment registers and the push/pop all instructions
 2020-10-22 19:10:28 -07:00
Ryan Houdek 9888141feb Some more table fixes 2020-10-22 19:10:28 -07:00
Stefanos Kornilios Mitsis Poiitidis 93e372c7a4 IR/JITs: Inline Constants Implementation 
Based on @phire's idea, Inline constants are constants that can be used as imms in instructions.

This
- Adds OP_INLINECONSTANT to represent them in the IR
- Modifies the ConstProp pass to transform OP_CONSTANT to OP_INLINECONSTANT based on per-platform heuristics
- Modifies the backends to use imms
- Supported opcodes: Add, Sub, Lsl, Lsr, Asr, Ror, Rol

Ryan Houdek 5af576b554 Fixes SetRoundingMode on AArch64 JIT 
Just needed to make sure to use the right register size
 2020-10-21 01:31:08 -07:00
Ryan Houdek 5d730db054 Fixes MEM_OFFSET size override. 
A couple of instructions were incorrectly marked as mem offset.
Fixes the mem offset literal size which is only modified with the
address size modifier.

Previously this was causing these instructions to narrow based on
operand size override incorrectly
 2020-10-17 20:22:21 -07:00
Ryan Houdek b17b3a5721 Fixes literal constant size 
It is the size in the bytes unless it is extended.
Once extended it should behave like the operand size
 2020-10-17 20:21:17 -07:00
Ryan Houdek dd49a04809 Fixes RIP literal sign extending on 32bit 
RIP Literal isn't actually RIP literal on 32bit, it is RIP absolute.
64bit treats the 32bit as a signed offset, while 32bit treats it as a
32bit unsigned offset

Stefanos Kornilios Mitsis Poiitidis 4111f795bd Merge pull request #458 from Sonicadvance1/fs_only_on_64bit 
Only sets up FS on 64bit
 2020-10-15 19:29:31 +03:00
Ryan Houdek 471f41fa62 Changes CPU family reported by CPUID 
Java VM uses this to determine if the CPU is new enough to be a 486 or
newer.

Also fixes some comment text.
Java VM scans all the leafs for hypervisor entries
Instead of adding directly which was causing our CPUID map to grow to
1500 entries.
Do the correct CPUID thing and return zeroes for non-understood leafs.
Gives us the same result since we cover almost all leaves with it anyway
 2020-10-13 13:19:07 -07:00
Ryan Houdek 00849a6fee Only sets up FS on 64bit 
Unnecessary when executing in 32bit since glibc will set up the TLS
 2020-10-13 12:29:19 -07:00
Ryan Houdek 101ef4f42d 32Bit Opdispatcher fixes 
Biggest thing is that it fixes segment register prefixing entirely.

Every op that supports segment prefixing now uses a helper to handle the
prefix
