Hi,
We noticed some performance gains if we are not using jump over some
simple switch statements. Here is the idea: Check whether the switch
statement can be expanded with conditional instructions. In that case
jump tables should be avoided since some branch instructions can be
eliminated in furth
sorry, The numbers were too good, something was wrong in my setup.
thanks, Dinar,

Another interesting use-case for OpenACC and OpenMP is mixing both
standard annotations for the same loop:
// Compute matrix multiplication.
#pragma omp parallel for default(none) shared(A,B,C,size)
#pragma acc kernels pcopyin(A[0:size][0:size],B[0:size][0:size]) \
pcopyout(C[0:size][0:size])
Hi,
I noticed some minor regression with singed integer operations in "the
proprietary" code since
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45232. Of course, I could
use "-fwrapv" flag but my question is: why we could not add overflow
checking in for example int_const_binop() at fold-const.c fo
Hi,
The current implementation of IPACP doesn't allowed to clone function
if caller(s) to that function is located in another object. Of course,
no such problems if we could utilized LTO. And it is very interesting
to have such functionality of compiler even without LTO. It could be
changed, if for

Hi,
I have observed that STV2 pass added ~20% on CPU2006 456.hmmer with mostly
by transforming V4SI operations. Looking at the pass itself, it looks like
it might be transformed into RTL architecture-independent, and the pass
deals only not wide integer operations. I think it might be useful on oth
