This is already fixed on the tree-ssa branch so suspending untill that branch gets pulled
into the mainline.

Note this is not really target spefic as it happens on every target with -fno-omit-frame-
pointer.

I still see this for the example given in comment #6 with 3.5-tree-ssa 20031216.
Are you sure it's fixed?

I think sparc's part gets fixed by: <http://gcc.gnu.org/ml/gcc-patches/2004-06/msg01049.html>.

------- Additional Comments From ebotcazou at gcc dot gnu dot org 2004-07-08 17:40 -------
This is fixed on SPARC thanks to tree-ssa. With the original testcase at -O2:
.file "pr6882.cpp"
.section ".text"
.align 4
.align 4
.global _Z6foobarv
.type _Z6foobarv, #function
.proc 020
_Z6foobarv:
.LLFB9:
jmp %o7+8
nop
.LLFE9:
.size _Z6foobarv, .-_Z6foobarv
.ident "GCC: (GNU) 3.5.0 20040705 (experimental)"
Falk, the example you gave in comment #6 appears to be specific to Alpha: it
doesn't generate epilogue/prologue code on SPARC with 3.4.x or mainline. So I'd
suggest to open a specific PR to track the problem. I'm closing this one.
