The following is just a prototype to try out a new qualifier type tag
proposed for DWARFv5. There is not even a draft yet of DWARFv5, so this
is just based on a proposal that might or might not be adopted and/or
changed http://dwarfstd.org/ShowIssue.php?issue=131112.1
I have a corresponding patch
Fixes unused "mode" and "in_p" argument names. Neither mips_move_to_gpr_cost
nor mips_move_from_gpr_cost care about the mode now, so I just removed it.
Thanks,
Richard

Convert references to gcc.gnu.org to use https.

Committed.

Can you provide some reference for that assertion?

Hello,
a trivial patch to remove a duplicated option, you can see the second one

this list is strange)
This was included in the bootstrap of another patch.

Hello,
I followed the advice in this discussion:
https://gcc.gnu.org/ml/gcc-patches/2014-04/msg00269.html
and here is a new patch. I made an effort to isolate a path in at least
one subcase so it doesn't look too strange that the warning is in this
file. Computing the dominance info just to tw

I fixed that with previous commit too (what happened is that I managed to
copy wrong version of the files while testing that they fail on AIX.
They indeed did fail, but for wrong versoin)

This fairly tedious patch refreshes the FAQ, including adding some

Many targets do not have both rotate and rotatert. Of the 47 targets
in the tree, 17 have both, 9 have only rotate, 2 have only rotatert, and
19 have neither (this is based on "grep -wil" so it can be slightly off).
rs6000 has only rotate, and mips has only rotatert. For such targets

Hi,
this is patch to add the used_by_single_function flag to varpool. In full
generality
it is a simple dataflow problem, since the variable may be referred by other
variables
as long as all of them are used by one function only. I have
bootstrapped/regtested it
on x86_64-linux and lto-bootstr
Hi Richard,
In this change:
https://gcc.gnu.org/ml/gcc-patches/2014-06/msg01278.html
where substitute_and_fold() was changed to use a dom walker, the calls
to purge dead EH edges during the walk can alter the dom-tree, and have
chaotic results; the testcase in PR 61554 has some blocks traversed

Hi,
The patch adds two hooks for backends to generate conditional compare
instructions.
* gen_ccmp_first is for the first compare.
* gen_ccmp_next is for for the following compares.
The patch is separated from
https://gcc.gnu.org/ml/gcc-patches/2014-02/msg01407.html.
And the original discussion
Hi,
The patch makes several functions global, which will be used when
expanding ccmp instructions.
The other change in this patch is to check CCMP when turning code into
jumpy sequence.
OK for trunk?
Thanks!

Hi,
Swapping operands in a ccmp will lead to illegal instructions. So the
patch disables it in simplify_while_replacing.
The patch is separated from

To make it clean. The patch adds two files: ccmp.{c,h} to hold all new
