If you don't set MAIN_STACK_BOUNDARY to 128, gcc may
align stack in main.
I am seeing some instability in the testsuite results when I don't redefine

On reflection, we should be able to dump all the stack related setting in
darwin.h and use the current setting of PREFERRED_STACK_BOUNDARY_DEFAULT 128
since current gcc now defaults on SSE2.

Looking through the remaining ICEs with -fgraphite-identity, the majority seems
to fall into this category.

This bug doesn't occur with the actual committed version of the cleanups to
i386 prologue/epilogue generation (as opposed to the proposed patches). Let's
leave this open for now in case it reappears

Unverified but I am told that this issue should be fixed in Xcode 3.2.3.

This failure is likely due to using Xcode 3.2.3 and is described in the thread
at...

New checks have been added to the linker to catch

The linkage of events succeeds if done manually (without using libtool which
invokes dsymutil)...

Apparently this structure is generating the duplicate AT_byte_size
attributes...
/* This structure is used when registering native methods. */
typedef struct
{
char *name;
char *signature;
void

This same structure for JNINativeMethod appears to be the source of the
duplicate AT_byte_size in all four failing libjava testcases.

On x86_64-apple-darwin10, these failures at -m32 and -m64 appear to be
suppressed when building with --enable-checking=release and reappear when
building with --enable-checking=yes.
