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/init/new27.C | 40 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 gcc/testsuite/g++.dg/init/new27.C (limited to 'gcc/testsuite/g++.dg/init/new27.C') diff --git a/gcc/testsuite/g++.dg/init/new27.C b/gcc/testsuite/g++.dg/init/new27.C new file mode 100644 index 000000000..a6271c930 --- /dev/null +++ b/gcc/testsuite/g++.dg/init/new27.C @@ -0,0 +1,40 @@ +// PR c++/34862 +// { dg-do run } +// { dg-options "-O2" } + +typedef __SIZE_TYPE__ size_t; +extern "C" void abort (); + +struct T +{ + void *operator new (size_t, char *&); + T () { i[0] = 1; i[1] = 2; } + int i[2]; +}; + +void * +T::operator new (size_t size, char *&p) +{ + void *o = (void *) p; + p += size; + return o; +} + +T * +f (char *&x) +{ + return new (x) T (); +} + +char buf[10 * sizeof (T)] __attribute__((aligned (__alignof (T)))); + +int +main () +{ + char *p = buf; + T *t = f (p); + if (p != buf + sizeof (T)) + abort (); + if (t->i[0] != 1 || t->i[1] != 2) + abort (); +} -- cgit v1.2.3
