You need a proper patch, not instructions.
However, it's clear from the bugreport and the patches required to fix it, that
it is not important whether the target is m68k-amigaos or another OS.

those files are just imported in GCC and are handled as a separate project.

The issue is that we do not do predicated value-numbering so we need multiple
invocations of it. Which all of FRE, DOM and PRE do - but PRE is not run at
-Os in 4.4.
And yes, the optimization done by 4.5 is correct

Here is a small testcase:

void jumpfunc(int copy, void *p)
{
void *l = &&jumplabel;
if (copy)
__builtin___memcpy_chk (p, l, 128, __builtin_object_size (p, 0));

I just ran into a bug that this feature would have found for me at
compile-time. Instead, it required exercising the code under valgrind, which
took quite some time. If voting were enabled, I would vote for this bug.

Well with: int32_t actuallyRead = read(&v, SIZE_OF_BYTE);
And inlining turned on all the way, this:

memcpy(data, _totPtr, toRead);
Becomes just:

It would be nice if __attribute__((warning(""))) (and error) worked anywhere
