Ack! Sorry--I had indicated the wrong target on that one. The target is
vxworks, not linux. My 4.1.1 powerpc-linux compiler *does* get this
optimization right. So something in the vxworks-specific code is causing this:
/opt/vxppc/libexec/gcc/powerpc-wrs-vxworks/4.1.1> ./cc1 -m32 -Os ~/foo.c -o -
-quiet
.file "foo.c"
.section ".text"
.align 2
.globl foo
.type foo, @function
foo:
stwu 1,-16(1)
li 3,1
addi 1,1,16
blr
.size foo, .-foo
.align 2
.globl bar
.type bar, @function
bar:
stwu 1,-16(1)
addi 1,1,16
blr
.size bar, .-bar
.ident "GCC: (GNU) 4.1.1"
In my opinion, this is a very low priority problem, despite that this is one of
my primary development environments. Sorry for wasting your time with the
wrong target.
