Hello all,
I have noticed that when strict_low_part is used in a patten we need
to use '+' as the constraint modifier if any constraints are used in
the patterns.
Why is this so?

No, it is not. It is missing from GENERAL_REGS but not from ALL_REGS.

Yes.

For now, yes, I chose to suppor

Stack register is missing from ALL_REGS.
Are registers 16bit? Is just one required for pointer?

Well, I think so:

NO_REGS,

Are you sure your "z" constraint only matches even numbered hard
registers?

The scheduler works over regions. It doesn't look at barriers.

In the following code I marked the tree 'node.0' as address taken using
'c_mark_addressable'. Now in the assembly code, isn't the return value of the
second call to malloc completely discarded?
This problem does not arise in -O0. Here I'm using -O2.
main ()
{
void * D.2897;
struct node * D.2

The GCC 4.2 branch is open for commits under normal release branch
rules. All fixes going on that branch should first have gone on trunk
and 4.3 branch.
I propose to build 4.2.4-rc1 once we have resolved what if any changes

Ok, I reserved r0 (BP_REGNUM) for such reloads, and I'm generating new
instructions in LEGITIMIZE_RELOAD_ADDRESS to calculate

The error is rectified. The bug is in the function that calls fuse_loops().

i have a doubt about unSSA: is it allways possible to map back the

is there an algorithm that describe this translation back?

Hello all,
I got few doubts regarding the way in which scheduling works in gcc 4.1.2
1. Will barrier insns gets scheduled along with other instructions?
2. When there is an unconditional jump in the instruction list, a
barrier instruction gets emitted after the unconditional jump as the
last inst
