If even fake registers like these are going to be used, then I think

Thanks for the explanation, now I understand it. I fixed the patch
according to your remarks. I removed %| support since we don't
actually need it in i386 right now, it was added for the purpose of
possible generalization.

Hi,
I added two testcases to this patch. So that we might detect
regressions about this issue later more easily.

Hi!
On the attached testcase prg_ctr_mask is non-zero, presumably set
while there still were some functions in the TU, but later on none of them
are being emitted. This leads to n_functions in coverage_obj_finish being
0, and the array thus containing 0x1 elements.

Hi!
This is a follow-up fix for my earlier commit, in merge_exception_specifiers
can be NULL, noex == boolean_true_node comparison then was false, but
operand_equal_p crashes on it.
Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux, ok for

Hi!
Various TM tests ICE when built with -fgnu-tm -fsanitizer=address.
The problem is that asan.c pass adds calls to builtins that weren't there

Hi!
This is something I've changed recently on the C++ side, but C has similar
issue as the testcase shows. For m or other constraints that allow memory
and don't allow registers, we want to mark the operand addressable (thus

The small memory model will not do since I want to put data at other
distinct addresses above 4G. I also want to place the heap at yet another
address interval. This way it becomes easy to separate out code, data and
heap references, and making sure that pointers are valid. The primary reason
