Hi,

Yes, we got this error on SH72513(SH2A) hardware. When the same code
is run on simulator, the "address error" occurs on encountering the
"fmov.d" instruction.

Hello,
Looks like you are mixing ABIs. what is you fpscr setting ?
From my understanding, if the fpscr PR bit is set to 0 the 64-bit
operation behaves as 2 32 bit operations (paired single precision). so I
don't think you get an address error here.

Jeff,
I take your point and will go back over my splitters as I know one
instance in which a splitter can create such an issue.
(I should checlk for a constant operand after simplifying an operand).
In the cases I looked at before this was not the situation.

Hi guys,
I'm interested in what if any issues exist in bringing ObjC 2.0 to the trunk of
GCC. I spoke with someone recently who claimed that there were GPLv3 problems
with Apple's code, is this correct?
Thanks, GJC

The 4.0.x branch was R.I.P.ed.
Commiting 4.1.x, 4.2.x, 4.3.x and 4.4.x means 4 times of efforts than 3 times.
They are very similar in design, they use TreeSSA, autovectoring, etc.
It's recommended to be online 4.2.x, 4.3.x and 4.4.x branches.

Once the files have been completely parsed, how can I traverse through
all global declarations (e.g. types and variables) ? I can find the
functions by traversing the call graph but would like to know how to
do the same for types and variables. Also is there a way to find a
decl from its UID?

What prevents you from doing the comparaison yourself using SVN?

Hi list,
gcc-4.3 appears to make quite heavy use of cmov to eliminate
conditional branches on x86(-64) architecture, even for those
branches that are determined to be predictable.
The problem with this is that the data dependancy introduced
by the cmov can restrict execution, wheras a predicted b
