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/warn/Warray-bounds-4.C | 37 +++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 gcc/testsuite/g++.dg/warn/Warray-bounds-4.C (limited to 'gcc/testsuite/g++.dg/warn/Warray-bounds-4.C') diff --git a/gcc/testsuite/g++.dg/warn/Warray-bounds-4.C b/gcc/testsuite/g++.dg/warn/Warray-bounds-4.C new file mode 100644 index 000000000..319038a73 --- /dev/null +++ b/gcc/testsuite/g++.dg/warn/Warray-bounds-4.C @@ -0,0 +1,37 @@ +// { dg-do compile } +// { dg-options "-O2 -Warray-bounds" } + +class String +{ +public: + virtual unsigned long length() const = 0; + virtual char get(unsigned long index) const = 0; + virtual void set(unsigned long index, char value) = 0; + virtual char& operator[] (unsigned long value) = 0; + virtual ~String() {}; +}; + +template class FixedString : public String +{ +private: + char contents[size]; + +public: + virtual unsigned long length() const { return size; } + virtual char get(unsigned long index) const { return contents[index]; } + virtual void set(unsigned long index, char value) { contents[index] = value; } + virtual char& operator[] (unsigned long index) { return contents[index]; } + + FixedString() { contents[0] = '\0'; } // { dg-warning "above array bounds" } +}; + +void print_length (const String& string); + +int main() +{ + const FixedString<0> empty; + + print_length(empty); + + return 0; +} -- cgit v1.2.3
