From 10e08855d74dc3f35bb295ac2747f48dd037bee6 Mon Sep 17 00:00:00 2001 From: Thomas Preud'homme Date: Thu, 8 May 2014 01:19:11 +0000 Subject: [PATCH] re PR middle-end/39246 (FAIL: gcc.dg/uninit-13.c) 2014-05-07 Thomas Preud'homme 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.
