Do you have any suggestion how this could be enhanced? We know that
better documentation may help, but at some moment one has to get the
hands dir
Hi,
I've tried to use the treebrowser described at
http://gcc.gnu.org/projects/tree-ssa/tree-browser.html
I configuired gcc-4.5.0 with ... --enable-checking --enable-tree-browse
--enable-tree-checking ...
Compilation was OK, a gcc/tree-browser.o exists.
Now i'm able to launch gdb and step throu

That is good, but to get help you really need to ask specific
questions. Show us an insn pattern, tell us what you are trying to
do, tell us what you did, tell us what happened.

Read the internals manual to understand how operand predicates and
constraints work. See the hundreds of existing examples. Ask if you
have spec
Hi,
I want to change instruction blez to ble. ble compare two registers and jump

Hi Edmar,
I have been testing your patch on our port of GCC4.4.1. The patch
works well, although I stumbled on an issue.
Many of our interesting cases have large case values, so profiling
the default range of values 0 - 255, or even as large as 0 - 2047 is
insufficient. Profiling for a larger ran

_REENTRANT does essentially nothing (enables getlogin_r when the rest of
POSIX.1:1996 is disabled). See what I said

? gcc mailing list certainly worth reading for users. I always thought
that -lpthread at link time is enough.

There is an old PR about this: http://gcc.gnu.org/PR16519

What reasons keep you from contributing to GCC?
I tried this a while ago, but ultimately gave up because I could not get my
patches in. Some were applied, but many never made it. Admittedly they were
