Division is inlined with -fcx-limited-range.

These targets are using -Os to build target libraries. Perhaps the
right thing to do instead would be to disable some optimizations
selectively in the compiler?
Thanks!

A RECORD_TYPE is wha
Let me revive this thread and ask for suggestions/tips on the issue below.

Hi,
RTEMS has been using simulators and some
programs we wrote for coverage analysis
for a while now.
I am looking into writing a converter which
takes coverage data from simulators and produces
.gcno files. The coverage data is often just
a bitmap of which addresses were executed. There

Hi,
I'm currently working on trying to implement a way to use the SIMD
instructions of the SSEx family when computing a vector of complex
numbers.
I have to say that I have never worked on compilation techniques before,
and that I only have little understanding of the vectorization problems.

Hi,
I would like to experiment with modifications to the instruction flow
during scheduling. One motivation for doing that is the combining of
contiguous loads like was discussed here:
http://gcc.gnu.org/ml/gcc/2010-12/msg00153.html
I've seen that the scheduler itself does some modifications to t
