typedef struct { int bits : 24; } int24_t;
typedef struct { unsigned bits : 24; } uint24_t;
This is as close as you can get, and these structs will be 4-byte
aligned.

GCC does value analysis similar to what you mentioned. You'll find it
under the -fdump-tree-vrp options. To provide extra information you
can add range checks which GCC will pick up on. If you know a value is
small, use a small integer type and gcc will pick up the range of
values which can be assi

Hi,
Does anyone know if it is possible to view/access/print out the
control flow graphs produced by GCC, either at compilation time, or
after compilation has taken place?
Thanks for your time.
Rob
can say whether properties of concurrent
programs hold for all the possible interleavings. However, it was
decided that that was too complicated, so it was narrowed to
non-concurrent programs.

Thanks again.

I haven't looked into this yet, but as I think I may need to be able
to do something similar, is it possible to parse the cfg file that is
given out, and build a C structure like that?
Thanks

Hi,
I am considering trying to add DW_AT_start_scope attributes to the
debug info emmited by GCC, so it can be used by GDB. I just wanted to
know what people think about this, and how difficult it is likely to
be?
Thanks for your time.
Rob
assuming no-one has any objections, my question is, how do I go
about trying to do it in GCC? What should I look at and where should I
look?
Thanks for your help.

So the general concensus is that's it's not worth doing?
Hypothetically, if I did it and it didn't make much difference, would
it be worth submitting a patch? Or should I just give up before I
start?

Bugs in the test framework effect our ability to work on the
toolchain efficiently, but other than the handful of people here, nobody
cares. Forgetting the refactoring daydream, testing patches and doing
releases still needs to be done, so I think we need a long-term solution
and fresh
only used in
the current century.
Right now working through patches is probably more important. :-)
There's zero patches on the DejaGnu savannah site, so I'd ask anybody to
submit them so I don't have to dig them out of email archives.

suite ones will go in first since they don't effect the toolchain.
Jacob already added 9 patches to our site. I'm still building cross
compilers since some of his patches effect cross testing. I did add ADA
to my builds, which isn't a normal build default, since I thought some
of the patches for ADA.

Gnu doesn't change much, and there were only 2
of us working on it, so we just never thought about it.

I processed the patch backlog for DejaGnu, and have gone through the
bug list. It'd be nice if somebody could try master with a more complex
environment, etc... if I'm going to push out a release. For cross
testing all I have is a PI and QEMU.

I don't think it was that we were happy with expect, but at least for
GDB testing, nobody has any alternatives. I thought I mentioned that a

else wouldn't require it. That also means all the remote execution procs
would need to work without expect as well.
