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++.old-deja/g++.warn/impint2.C | 69 +++++++++++++++++++++++++++ 1 file changed, 69 insertions(+) create mode 100644 gcc/testsuite/g++.old-deja/g++.warn/impint2.C (limited to 'gcc/testsuite/g++.old-deja/g++.warn/impint2.C') diff --git a/gcc/testsuite/g++.old-deja/g++.warn/impint2.C b/gcc/testsuite/g++.old-deja/g++.warn/impint2.C new file mode 100644 index 000000000..d5fbc5554 --- /dev/null +++ b/gcc/testsuite/g++.old-deja/g++.warn/impint2.C @@ -0,0 +1,69 @@ +// { dg-do assemble } +// { dg-options "-Wconversion" } + +// Copyright (C) 2000 Free Software Foundation, Inc. +// Contributed by Nathan Sidwell 6 Mar 2000 + +// initialization to 'int' from to 'double' We expect consistent warnings +// whenever a float is implicitly truncated to int, make sure references +// don't confuse us, as Gerald Pfeifer found out. + +struct X +{ + X (int const &); + X (int const &, int const &); +}; + +void foo (int const &); +void wibble (int const &); +void wibble (int const &, int const &); +void punk (int const & = 3.5f); // { dg-warning "" } in passing +void rock (); +void rock (int const &, int const & = 3.5f); // { dg-warning "" } in passing + +void fn () +{ + X x2(3.5f); // { dg-warning "" } float to int + X x4(1, 3.5f); // { dg-warning "" } float to int + X x6(3.5f, 1); // { dg-warning "" } float to int + + X y2 = 3.5f; // { dg-warning "" } float to int + + int j2 (3.5f); // { dg-warning "" } float to int + + int k2 = 3.5f; // { dg-warning "" } float to int + + j2 = 3.5f; // { dg-warning "" } float to int + + foo (3.5f); // { dg-warning "" } float to int + + wibble (3.5f); // { dg-warning "" } float to int + wibble (1, 3.5f); // { dg-warning "" } float to int + wibble (3.5f, 1); // { dg-warning "" } float to int + + punk (); // { dg-warning "" } float to int + rock (1); // { dg-warning "" } float to int +} + +// and make sure we really know when something's unsigned +void foo () +{ + X x2(-1); + X x4(1, -1); + X x6(-1, 1); + + X y2 = -1; + + int j2 (-1); + + int k2 = -1; + + j2 = -1; + + foo (-1); + + wibble (-1); + wibble (1, -1); + wibble (-1, 1); + +} -- cgit v1.2.3
