This normally means that you need a copy_rtx somewhere. Different insns
may not share data structure.

Suppose you're writing the backend for a VM supporting two architectures, in
which
one of them clobbers the CC registers for certain instructions, while the other
does not.
The instructions themselves are exactly the same.
What is the best/shortest/more-elegant way to write this, possibly w/out

Hi,
Its fixed for me. I was missing get_ref_tag () in copy_ref_info () when
I patched against 4.5.
Thanks again,

Hi,
I'm working on a new transformation pass.
During this pass the whole TREE of a function is parsed using tree
walker, and code is inserted (using BIND_EXPRs).
The problem is that i'm having a false assertion
"at make_decl_rtl, at varasm.c:1273"
This is the line N°1273 of varasm.c

The problem is when I have to clobber ACC such as when moving between
