Need to sign extend, otherwise junk from upper bits
can mess things up.

545b542f9b GdbServer: Implement xml target for register order 
We can now simply memcpy much of memory state.
 2020-03-06 07:56:01 +02:00

e44b3ca495 Gdbserver: Implement enough to reach gdb prompt 
Memory is implemented, but without any checking or
invalidation.
Registers just hardcode a RIP for my test elf.

But GDB can read the elf over tcp, initilize and allow you to create breakpoints, which get
writen back before continue (which is not hooked up)

e0e708a9c0 Fixes three instructions necessary for shared apps to run 
Fixes MOVHPD which was failing.
Fixes FXSTOR and FXSAVE which was accidently loading the memory location
rather than doing an LEA of the address.

9c873d85ec Fixes mmap syscall to work for dlopen and dlsym 
This makes my test app that is loading ld.so with dlopen actually work.

af5a562508 Fixes bug in STOS and CMPS 
We were storing one too many elements. So even if the counter register
was zero it would do a store or comparison
 2020-03-06 07:56:00 +02:00

8a6efad301 Stub FNSTCW/FLDCW so libc.so.6 can be loaded 
Apparently doesn't need any other x86 instructions.
Or anything more than noped out state save/restore.

e9923fa704 Add lseek syscall 2020-03-06 07:56:00 +02:00

3f06f3e87d Fixes bug in PUSH op with RSP source. 
We were modifying RSP to adjust the stack first.
Then if the source used RSP then it was offset by the store size.

`push [rsp]` was broken before this

2df55d303a Fixes bug in SHR op 
Smaller ops could have been shifting data from the larger source in to
the smaller op space when it should have been zero'd
 2020-03-06 07:55:59 +02:00
Ryan Houdek
7a4d0fbfd3 Fixes bug in 64bit def mod instructions that are in 16bit mode 
These would have been forced to 64bit when they would have wanted to be
operating in 16bit mode.
Fixes that.
 2020-03-06 07:55:59 +02:00
Ryan Houdek
afdbd9ebdc Fixes issues with PSLLDQ and PSRLDQ 
These are whole vector shift instructions and they shift by bytes rather
than bits.
You only get an immediate offset for the instruction.
Implements two new IR ops to account for these instructions

This also doesn't match AArch64 behaviour 100%, requires two
instructions to emulate rather than the single one on the x86-side
 2020-03-06 07:55:59 +02:00
Ryan Houdek
af6eefb495 Fixes crash in IR Interpreter that can occur with large functions 
If the tmp space grew too large and had to resize then we would have
stale pointers.
Keep around the offset instead so we don't store invalid pointers.
