Ryan Houdek ba3cb444ee Ensures test harness runner runs in 64bit mode 2020-05-14 01:03:42 -07:00
Ryan Houdek d2cf07a4fd Passes the running mode through from FEX to FEXCore 2020-05-14 00:56:31 -07:00
Ryan Houdek b70176c99a Fixes bug in TypeDefinition elements 
Elements of 0 isn't a real thing. Would cause problems in the CPU
backends.
Ensure we have at least 1 element (Which technically means a vector 1
element wide, but that just defines as a scalar)

Ryan Houdek cda734cea2 Adds support for comment lines in the IR parser 
Comments start with ';' on the line.
You can also technically have comments after IR ops but that isn't
explicitly supported, just an artifact of how things are parsed.

Ryan Houdek 718b3e6b4c Refactors PassManager to ingest IREmitter class instead of OpDispatcher 
The Passmanager passes need very little or zero x86 knowledge to do
their work. They don't need the x86 OpDispatcher handling code at all.
Convert this entirely over to using the IREmitter class so it can
actually optimize IR code from the IRLoader frontend
 2020-05-09 12:14:59 -07:00
Ryan Houdek dff0a8fb69 Switch the IRLoader over to using the IREmitter class 
Reduces some code duplication

Ryan Houdek 9fd3cd8884 Implements IR loader frontend application 
This application loads an IR from an IR file.
It then proceeds to lex the file and translate it to binary IR.
Once the file is loaded it then the IR is passed off to the backend and
it attempts to run the IR.

This will be used when debugging RA and writing unit tests directly in
IR.
This is a necessary evil for ensuring correctness

David Miller 09f119a3ce removed front end header / class from EmulatedFiles.cpp 2020-04-29 16:39:40 -04:00
David Miller 306cca33d7 Added dup3 syscall, EmulatedFiles : /proc/{self,$PID}/auxv, modified OpenAt() to normalize path to canonical if possible or lexically_normal. Note: canonical will change symlinks, ensure the map keys take this into account. 2020-04-29 16:00:59 -04:00
Ryan Houdek 3528b30684 Fixes loading EXEC applications in to memory. 
If we are loading EXEC then we actually need to start loading in to the
lower 32bits of memory.
This lets the frontend code loader handle the memory base instead of
hiding it behind some core magic instead.

This lets us get EXEC programs working.
So now we support EXEC, DYN, and static applications

David Miller 5999e7477f Added guard around llvm/IR/IntrinsicsX86.h inclusion, seems to only be needed for version 10?\nMore Investigation needed here.\nChanged Debugger/IMGui.{h,cpp} to IMGui_I so it will build in filesystems that aren't case sensitive.\nAdded CMakeSettings.json that has profiles to build from VisualStudio, using env variables to control system specific options. \n Currently only the WSL is tested (and working). \nRemote should work as well, if correct string for preconfigured remote is in env variable fexremote.\nCross compile (to linux) untested, using sysroot in env variable fexsysroot 2020-04-23 16:12:28 -04:00
Ryan Houdek 780278a7f6 Fixes memory allocation 
4GB virtual memory is too small and causes things to fault.
Previously we were at `1 << 36` but it caused oom issues on devices with
smaller amounts of memory.
This time ensure the the SHM memory is allocated with MEM_NORESERVE so
devices can actually allocate the virtual memory region.

Ryan Houdek 3424326987 Removes accurate-std command line argument 
This is an option that has been removed
 2020-04-09 18:01:29 -07:00
Ryan Houdek 5298379fb9 Ensure the ELFLoader doesn't end up in the lower 32bit address space 
We need to reserve that space for EXEC apps and 32bit apps. Hard throw a
warning if any of our mapping space ends up in the lower 32bits.

PIE and potentially a custom dynamic linker can enforce this.

Ryan Houdek 15d5ba6fc1 Adds RootFS search path in ELFLoader 
Fixes #69, makes it less annoying to run things on non x86 hosts
 2020-04-04 23:17:40 -07:00
Ryan Houdek 3fd1475d30 Plumbs ELFLoader arguments through the CodeLoader 
This is necessary for execve in the future to keep everything in sync
 2020-03-21 15:19:31 -07:00
Ryan Houdek e5dc72ad69 Fixes the dynamic linker detection 
Fixes #49

Makes it so we no longer have to pass in the ld location to the
ELFLoader application.

Once we switch over to the dynamic linker, the program being executed to
us is no longer a dynamic program.
But the frontend ELF loader also still needs to know that we are
executing the dynamic linker so it can append the linker to the
arguments.

Ryan Houdek 4ea18647ed Make the unit test runner allocate less SHM space 
It doesn't need 64GB of virtual memory, so knock it down to its minimum
virtual memory required

Ryan Houdek a2afd684ae Allows ELF loader to pull in all environment variables

various other bits

Ryan Houdek c0b3a94e4f Fixes up stack space for argv and envp 
These were messy and we were previously losing a page for random
"redzone" which doesn't matter.
We only needed 16bytes more for some additional padding that was needed
for something
