The problem appears to be that you've got *partial* debug_frame
information, but it's wrong. I'm not 100% clear on what's the
First Cause on the wrongness.
I will say that I suspect that we probably want to just say
that any target that doesn't provide DWARF2_UNWIND_INFO or

We don't have the resources to help with very old versions of gcc on

This is from the gdb.base testsuite:
int factorial (int value)
{
if (value > 1) { /* set breakpoint 7 here */
Consider the file xordi.c:
signed long long int xordi (signed long long int a, signed long long int b)
{
return (a ^ b);
}
Compile like this (GCC version 4.1.0 20060304 (Red Hat 4.1.0-3)):

Right : A way to work around this would be to hold to not match this
instruction until reload has been completed and have a define_split to
convert this to a cmp , bne when its a memory operand matching . Look at
rs6000.md or mt.md for a sample implementation.
What I am saying is the following.

Remove it. It's now done with NUM_REFERENCES which just uses
common.aux. Dan probably forgot to remove it when he converted it.

Hi,
I've been having some odd problems with relocation of 4.x toolchains -
i.e. when a toolchain is configured, built and installed with one prefix
but later moved to another location. The binaries appear to be checking
something in the old location before reading from the new path.

Hi,
I had wrote doloop_end instruction to support hwloop.
When try to compile linux kernel, I meet a reload problem,

What kinds of instuction pattern should I add to support
the reload that compiler need ?
Thanks,

Also, is there a function for simplifying a zero_extract?
What combine is doing is to expand compound operations such as
zero_extract, simplifying them, and try to make new compound operations.
Therefore you should first try to understand what's causing combine to
miss the simplification.
Combine is trying to find this instruction (when compiling _popcountsi2 from
libgcc2.c for my i8086 experiment):
(set (subreg:QI (reg:HI 30) 0)
(mem/s/u:QI (plus:HI (subreg:HI (zero_extract:SI (subreg:HI (reg/v:SI 22 [
