Default defs are SSA names without an explicit defining statement for example

Regarding the other question I asked today could somebody explain to

I'm encountering a really painful error. The stack trace is below.
The code in hash-table.h is a template and it is really hyper-allergic
to instrumentation (a couple of fprintfs caused malloc to have an
internal error!) Last time I checked gbd didn't exactly play nice
with templates either. Note
I tested the release candidate on powerpc64 power 7 BE, power 8 BE,
power 8 LE, and power 9 LE and everything looked OK.

Hi Florian,
I understand you want to discuss the x86_64 micro-architecture levels
only in this thread, but it would be nice to have a similar discussion
for other architectures.
One thing that wasn't clear to me from this proposal is how the glibc
dynamic loader checks for the CPU feature flags.

Hi,
I narrowed down that ipa-inline is marking these indirect functions as
unreachable (these functions have been specialized and therefore should
now be direct functions). Therefore, symtab_remove_unreachable_nodes is
called on them. Running the following (immediately after materialization):
Hello!
Thank you very much. I use the following statement to check and I confirm
that it's not SSA_NAME:
if (TREE_CODE(operand) != SSA_NAME) return;
But considering the following code snippet:
_313 = _312 + 2147450880;
_314 = (signed char *) _313;
_315 = **_314*; // _314

Hello,
I am using the following code to iterate different gimple statements:
...
gimple* stmt = gsi_stmt(gsi);
if (gimple_assign_load_p(stmt)) {
tree rhs = gimple_assign_rhs1 (stmt);
if (!rhs) return;
gimple* def_stmt = SSA_NAME_DEF_STMT(rhs);
if (!def_stmt) return;
