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. --- .../random/discrete_distribution/cons/default.cc | 44 ++++++++++++++ .../random/discrete_distribution/cons/initlist.cc | 43 +++++++++++++ .../discrete_distribution/cons/num_xbound_fun.cc | 70 ++++++++++++++++++++++ .../random/discrete_distribution/cons/range.cc | 46 ++++++++++++++ 4 files changed, 203 insertions(+) create mode 100644 libstdc++-v3/testsuite/26_numerics/random/discrete_distribution/cons/default.cc create mode 100644 libstdc++-v3/testsuite/26_numerics/random/discrete_distribution/cons/initlist.cc create mode 100644 libstdc++-v3/testsuite/26_numerics/random/discrete_distribution/cons/num_xbound_fun.cc create mode 100644 libstdc++-v3/testsuite/26_numerics/random/discrete_distribution/cons/range.cc (limited to 'libstdc++-v3/testsuite/26_numerics/random/discrete_distribution/cons') diff --git a/libstdc++-v3/testsuite/26_numerics/random/discrete_distribution/cons/default.cc b/libstdc++-v3/testsuite/26_numerics/random/discrete_distribution/cons/default.cc new file mode 100644 index 000000000..9d05b1982 --- /dev/null +++ b/libstdc++-v3/testsuite/26_numerics/random/discrete_distribution/cons/default.cc @@ -0,0 +1,44 @@ +// { dg-options "-std=c++0x" } +// { dg-require-cstdint "" } +// +// 2008-12-03 Edward M.
