SDE debug not working on OS-X

TIMOTHY_R_Intel — Thu, 23 May 2019 19:09:59 GMT

Trying to use "-debug" to diagnose where an errant instruction is being called from, but on OS-X I'm getting an error saying that the version of "pin" bundled with SDE does not support the "-appdebug_lldb_options" option.

$ ~/Downloads/sde-external-8.35.0-2019-03-11-mac/sde64 -nhm -- ./point_geometry

TID 0 SDE-ERROR: Executed instruction not valid for specified chip (NEHALEM): 0x7fff5aa69d2d: vmovups xmm1, xmmword ptr [rsi+rdx*1-0x10]

Image: /usr/lib/system/libsystem_platform.dylib+0x1d2d (in multi-region image, region# 0)

Function: __platform_memmove$VARIANT$Haswell

Instruction bytes are: c5 f8 10 4c 16 f0

$ ~/Downloads/sde-external-8.35.0-2019-03-11-mac/sde64 -debug -nhm -- ./point_geometry

E: unknown option "-appdebug_lldb_options"

Use -help for a description of options

Since you are internal, you

Since you are internal, you can contact the development team directly. If you don't know how, contact me.

That said, you can use debugtrace probably: -debugtrace -dt-call -dt-flush -dt-symbols

and if the output is long, -dt-circular-buffer 10000

(See -long-help output)

Hi- I'm having trouble

Hello,

I am having a similar issue on macOS Catalina:

./sde -pnr -- ~/my_exe TID 0 SDE-ERROR: Executed instruction not valid for specified chip (PENRYN): 0x7fff6eb2794d: vmovups xmm1, xmmword ptr [rsi+rdx*1-0x10] Image: /usr/lib/system/libsystem_platform.dylib+0x94d (in multi-region image, region# 0) Function: __platform_memmove$VARIANT$Haswell Instruction bytes are: c5 f8 10 4c 16 f0

It seems that macOS frameworks are not using the CPUID exposed by sde to choose which version of the version to use.

I could use "-chip_check_die 0" but this will emit TONS of warning as memmove and similar functions are use everywhere. Is there a way to suppress some libs ?

Regards

David

@r2d3, I'm having the same exact issue. Have you found a workaround?
