Running drmemory builds on Win10/64bit machines without AVX support ?

[Roland Mainz]

Hi!

----

Questions about https://github.com/DynamoRIO/drmemory/issues/2264 ("drmemory 2.6.19984/cronbuild on Win10/Workstation on IBM 7945/XEON crashes with ASSERT FAILURE"):
1. Is it possible to make ASSERTS in DynamoRIO non-fatal (i.e. warn, but do not terminate the process) ?
2. Is it possible to build the current DrMemory git HEAD without AVX support, for machines which do not have AVX (older XEON machines don't have AVX, and even in modern XEON machines AVX&co can be turned-off in the BIOS) ?

Bye,

I think you mean https://github.com/DynamoRIO/drmemory/issues/2514 and not the link you gave.

 

1. Is it possible to make ASSERTS in DynamoRIO non-fatal (i.e. warn, but do not terminate the process) ?

You mean in debug build only I assume.  Did you check the documented list of options?  See -ignore_asserts in that list https://drmemory.org/page_options.html

 

2. Is it possible to build the current DrMemory git HEAD without AVX support, for machines which do not have AVX (older XEON machines don't have AVX, and even in modern XEON machines AVX&co can be turned-off in the BIOS) ?

Yes it should be possible.  It is open source so you should be able to tweak the build flags in the CMake code.  You would have to ensure every compiled module (including DynamoRIO) is built without AVX.

For DynamoRIO, you can see -ignore_assert_list '*' at https://dynamorio.org/page_deploy.html#sec_options (using filenames needs full paths: https://github.com/DynamoRIO/dynamorio/issues/183).
