* 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.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
