Adding "--param allow-store-data-races=0" to the GCC options for the
kernel breaks C=1 because Sparse isn't expecting a GCC option with that
format.
It thinks allow-store-data-races=0 is the name of the file we are trying
to test. Try use Sparse on linux-next to see the problem.
$ make C=2 mm/sl

Please try --param=allow-store-data-races=0 instead.

How reliable is this format across
Hello All:
There has been work done for load rematerialization. Instead of Store and Load
of variables they kept in registers for the Live range. Till now we are doing
the rematerialization of scalar loads.
Is it feasible to have rematerialization for the vector Loads? This will be
helpful
Hello All:
I have worked on the Open64 compiler where the Register Pressure Guided Unroll
and Jam gave a good amount of performance improvement for the C and C++ Spec
Benchmark and also Fortran benchmarks.
The Unroll and Jam increases the register pressure in the Unrolled Loop leading

Btw, this just triggered my eye. So with lumping the predicate to the
capture without special separator syntax, it means that there's a
difference between "minus_expr
