See http://gcc.gnu.org/bugs.html for instructions. configure:3273: $? = 1 Investigating the problem; it seems that the cause is not related to SMS but rather to the doloop optimization which is enabled only when SMS flags are set. (but that also does not mean that doloop is the reason for the fail; it could be some later passes) The first file that doloop is applied on and causes bootstrap failure is bb-reorder.c. The problematic loop seems to be the last FOR_EACH_EDGE in connect_traces function which is inlined into reorder_basic_block.

[Bug tree-optimization/49695] New: conditional moves for stores
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49695
Summary: conditional moves for stores
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal

for (i = 0; i point1-len; i++)

}
For the above loop if-conversion is not been done in the tree level (compiled
with trunk -r176116). Seemingly this case is similar to the one in PR27313.
When using -ftree-loop-if-convert-stores I get 'tree could trap...' message
although I'm not sure why as there is a read in every iteration of the loop to
the memory location we write to.
Similar case appears in SPEC2006/libquantum.
Here's a snippet from .ifcvt file:
bb 3:
pretmp.6_33 = point1_3(D)-arr;
bb 4:
# i_27 = PHI i_22(7), 0(3)
i.0_6 = (unsigned int) i_27;
D.3689_7 = i.0_6 * 8;
D.3690_8 = pretmp.6_33 + D.3689_7;
D.3691_9 = D.3690_8-val;
if (D.3691_9 != 0)
goto bb 5;
else
goto bb 6;
bb 5:
D.3694_20 = (long long unsigned int) res_19(D);

hmmm... after reading Sebastian Pop's paper from the last summit (Improving
GCC’s auto-vectorization with if-conversion and loop
flattening for AMD’s Bulldozer processors) it's seems that we need to grantee
that point1-arr[i].val is writable when the condition is false which we can
not prove in this case. So that's not a bug, I apologize for the noise.

So that's not a bug, I apologize for the noise. Continuing reading the paper I see that under the 'If-conversion without restrictions' section there is a technique that allows to apply if-conversion in the above case by writing to artificial object that has been created by the compiler when the condition is false. I assume this method is not implemented in trunk yet.

My recent patchs for SMS (i.e., http://gcc.gnu.org/ml/gcc-patches/2011-05/msg01341.html), which are not approved yet, require some adjustments for this testsuite patch. So that's why I thought it will be better to wait for a approval for the new patches before pinging for the testsuite patch, avoiding the need to submit a follow-up fix for it. Also, currently trunk bootstrap is broken on ARM with SMS flags and I'm trying to figure out the problem... so once I'll locate this problem I'll go back to these patches and push them forward to trunk.
