It depends on the properties your pass requires. If you ask for
PROP_cfg and PROP_gimple_any then you should schedule it after the CFG
has been built, but i

Hello,
I'm planning to do some research on the optimization flags available
for GCC (currently, using 4.1.1). More in particular, we want to see
how we can come up with a set of combinations of flags which allow a
tradeoff between compilation time, execution time and code size (as
with -O

Hi!
I create test to reproduce issue with cpu2006/454.calculix
See attached. File e_c3d.f contains cutted subroutine from calculix.
tr535.f main entry point of the test. you can use go-script as a
reference how i get these results. find_stall.pl script which find
problem instruction combinations.

Please do not cross-post. Patches should go to gcc-patches@ only.

I am new to this list, so please excuse any obvious mistakes. I am
trying to check if two types are equal or one is derived from the
other within the compiler. One of the types is a struct that is
defined under the std namescope. How do I search for a "node" that is

Hi Ian,
sorry to bother again. I reduced the code (attached) that segfaults here
on Core 2 Duo [1]. If I add -fno-split-wide-types the code does not segfault.
That flag comes from your patchset [2].
execute:
# ./cc1 -quiet -m64 -O1 test.c -o test.o
Any ideas?

Yes, that is there. I have revision 121690.

Hi,
I am working on gcc 4.1.1 and Itanium architecture. I want to modify
the machine description of ia64.md to add some checks before each ld
instruction. the
following is the original define_insn:
