re PR middle-end/39246 (FAIL: gcc.dg/uninit-13.c)
2014-05-07 Thomas Preud'homme <thomas.preudhomme@arm.com>
PR middle-end/39246
* tree-complex.c (expand_complex_move): Keep line info when expanding
complex move.
* tree-ssa-uninit.c (warn_uninit): New argument. Ignore assignment
of complex expression. Use new argument to display correct location
for values coming from phi statement.
(warn_uninitialized_vars): Adapt to new signature of warn_uninit.
(warn_uninitialized_phi): Pass location of phi argument to
warn_uninit.
* tree-ssa.c (ssa_undefined_value_p): For SSA_NAME initialized by a
COMPLEX_EXPR, recurse on each part of the COMPLEX_EXPR.
testsuite:
* gcc.dg/uninit-13.c: Move warning on the actual source line where
the uninitialized complex is used.
* gcc.dg/uninit-17.c: New test to check partial initialization of
complex with branches.
* gcc.dg/uninit-17-O0.c: Likewise.
