"Unable to compile pcode: syntax error" on ppc64le binary #48

Open ruscur opened 4 years ago

ruscur commented 4 years ago

Hi,

Trying to decompile a PowerPC 64 LE binary from r2. The same binary opens and decompiles in Ghidra. I get the following:

Ghidra Decompiler Error: Protomodel : __stdcall: Unable to compile pcode: syntax error

I thought the autodetection could be failing - when I open Ghidra, it shows the lang sleigh as PowerPC:LE:64:A2ALT:default, so I tried setting r2ghidra.lang to that, but the same result occurs.

The binary is just a simple GCC 9 compiled C program (specifically this), but I doubt that matters. I can upload the binary somewhere if it's easier to debug.

Not quite sure what's going on (and why this is only happening in r2 and not Ghidra) so any assistance would be appreciated.

Yes, please share the binary.

@ruscur could you please upload the binary directly to the GitHub instead? Your link seems broken.

This should hopefully work. Still having the same issue.
