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/ipa/devirt-3.C | 63 +++++++++++++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 gcc/testsuite/g++.dg/ipa/devirt-3.C (limited to 'gcc/testsuite/g++.dg/ipa/devirt-3.C') diff --git a/gcc/testsuite/g++.dg/ipa/devirt-3.C b/gcc/testsuite/g++.dg/ipa/devirt-3.C new file mode 100644 index 000000000..2d7bb0ab0 --- /dev/null +++ b/gcc/testsuite/g++.dg/ipa/devirt-3.C @@ -0,0 +1,63 @@ +/* Verify that simple virtual calls on an object refrence are + converted to simple calls by ipa-cp. */ +/* { dg-do run } */ +/* { dg-options "-O3 -fno-early-inlining -fno-inline -fdump-ipa-cp -fdump-tree-optimized" } */ + +extern "C" void abort (void); + +class A +{ +public: + int data; + virtual int foo (int i); +}; + +class B : public A +{ +public: + virtual int foo (int i); +}; + +class C : public A +{ +public: + virtual int foo (int i); +}; + +int A::foo (int i) +{ + return i + 1; +} + +int B::foo (int i) +{ + return i + 2; +} + +int C::foo (int i) +{ + return i + 3; +} + +static int middleman (class A &obj, int i) +{ + return obj.foo (i); +} + +int __attribute__ ((noinline,noclone)) get_input(void) +{ + return 1; +} + +int main (int argc, char *argv[]) +{ + class B b; + if (middleman (b, get_input ()) != 3) + abort (); + return 0; +} + +/* { dg-final { scan-ipa-dump "Discovered a virtual call to a known target.*B::foo" "cp" } } */ +/* { dg-final { scan-tree-dump-times "OBJ_TYPE_REF" 0 "optimized"} } */ +/* { dg-final { cleanup-ipa-dump "cp" } } */ +/* { dg-final { cleanup-tree-dump "optimized" } } */ -- cgit v1.2.3
