Nikita,
The attached patch adds the options for an additional sub-build with
GASP support plus debugging info. Unfortunately there is no currently
way in our infrastructure to separately enable/disable debugging info
and our debugging assertions. Therefore the programs compiled with
"-inst -g" will run with lots of assertions that will slow the
execution, potentially significantly. So, this particular sub-build is
really only suitable for debugging. However, I did at least disable the
low-level tracing and stats collection with are made mostly redundant by
GASP instrumentation.
After applying this patch to the Berkeley UPC source tree, you will need
to reconfigure and build Berkeley UPC. Just as you passed
--with-multiconf=+opt_inst
(or similar) when configuring before, you will now want
--with-multiconf=+opt_inst,+dbg_inst
to get support for GASP both with and without debugging. Once you have
configured, compiled, and installed, the resulting complier should
recognize the case of "-g" and "-inst" together on the command line
(order doesn't matter) and use this new sub-build.
I have sanity-checked this by building a compiler configured as
described above and confirmed that "upcc -c -g -inst ..." attempts to
invoke the proper sub-build, and that the resulting object file and the
libs in that sub-build all contain debug info. However, I don't have
PPW or other GASP-enabled tools setup to perform a more complete test.
If you have any further problems, let us know.
