From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/g++.dg/uninit-pred-1_a.C | 63 ++++++++++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 gcc/testsuite/g++.dg/uninit-pred-1_a.C (limited to 'gcc/testsuite/g++.dg/uninit-pred-1_a.C') diff --git a/gcc/testsuite/g++.dg/uninit-pred-1_a.C b/gcc/testsuite/g++.dg/uninit-pred-1_a.C new file mode 100644 index 000000000..58bb9c5d4 --- /dev/null +++ b/gcc/testsuite/g++.dg/uninit-pred-1_a.C @@ -0,0 +1,63 @@ +/* { dg-do compile } */ +/* { dg-options "-Wuninitialized -O2" } */ + +typedef long long int64; +void incr (); +bool is_valid (int); +int get_time (); + +class A +{ +public: + A (); + ~A () { + if (I) delete I; + } + +private: + int* I; +}; + +bool get_url (A *); + +class M { + + public: +__attribute__ ((always_inline)) int GetC (int *c) { + + A details_str; + if (!get_url (&details_str)) + { + incr (); + return 1; + } + + *c = get_time (); + return -1; + } + + void do_sth(); + void do_sth2(); + + void P (int64 t) + { + int cc; /* { dg-bogus "uninitialized" "uninitialized variable warning" } */ + if (GetC (&cc) >= 0 ) + return; + + if (t && cc <= 0 ) /* { dg-bogus "uninitialized" "uninitialized variable warning" } */ + { + this->do_sth(); + return; + } + + do_sth2(); + } +}; + +M* m; +void foo(int x) +{ + m = new M; + m->P(x); +} -- cgit v1.2.3
