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-2.C | 62 +++++++++++++++++++++++++++++++++++++ 1 file changed, 62 insertions(+) create mode 100644 gcc/testsuite/g++.dg/ipa/devirt-2.C (limited to 'gcc/testsuite/g++.dg/ipa/devirt-2.C') diff --git a/gcc/testsuite/g++.dg/ipa/devirt-2.C b/gcc/testsuite/g++.dg/ipa/devirt-2.C new file mode 100644 index 000000000..d3181e4c0 --- /dev/null +++ b/gcc/testsuite/g++.dg/ipa/devirt-2.C @@ -0,0 +1,62 @@ +/* Verify that simple virtual calls using this pointer are converted + to direct calls by ipa-cp. */ +/* { dg-do run } */ +/* { dg-options "-O3 -fno-early-inlining -fno-inline -fdump-ipa-cp" } */ + +extern "C" void abort (void); + +class A +{ +public: + int data; + virtual int foo (int i); + int middleman (int i) + { + return foo (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; +} + +int __attribute__ ((noinline,noclone)) get_input(void) +{ + return 1; +} + +int main (int argc, char *argv[]) +{ + class B b; + int i; + for (i = 0; i < get_input(); i++) + if (b.middleman (get_input ()) != 3) + abort (); + return 0; +} + +/* { dg-final { scan-ipa-dump "Discovered a virtual call to a known target.*B::foo" "cp" } } */ +/* { dg-final { cleanup-ipa-dump "cp" } } */ -- cgit v1.2.3
