* alias.c (true_dependence_1): Always use get_addr to extract
true address operands from x_addr and mem_addr. Use extracted
address operands to check for references with alignment ANDs.
Use extracted address operands with find_base_term and
base_alis_check. For noncanonicalized operands call canon_rtx with
extracted address operand.
(write_dependence_1): Ditto.
(may_alias_p): Ditto. Remove unused calls to canon_rtx.
s/alis/alias in the ChangeLog
Patch was thoroughly tested on x86_64-linux-gnu {,-m32} and
alpha-linux-gnu for all default languages plus obj-c++ and go. While
there was no differences on x86_64-linux-gnu (as expected),
alpha-linux-gnu improved the result [1] for some hundred of PASSes in
gfortran testsuite [2].
OK for mainline?
OK. No addition tests needed since this is covered by the existing suite.
