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/Wparentheses-23.C | 121 ++++++++++++++++++++++++++++ 1 file changed, 121 insertions(+) create mode 100644 gcc/testsuite/g++.dg/warn/Wparentheses-23.C (limited to 'gcc/testsuite/g++.dg/warn/Wparentheses-23.C') diff --git a/gcc/testsuite/g++.dg/warn/Wparentheses-23.C b/gcc/testsuite/g++.dg/warn/Wparentheses-23.C new file mode 100644 index 000000000..cadc287fe --- /dev/null +++ b/gcc/testsuite/g++.dg/warn/Wparentheses-23.C @@ -0,0 +1,121 @@ +// { dg-do compile } +// { dg-options "-Wparentheses" } + +// Template version of Wparentheses-22.C. + +int foo (int); + +class C +{ + public: + C() + : b(0) + { } + + // Use default assignment constructor. + + // Provide conversion to bool so that an instance of this class will + // work as a condition. + operator bool() const + { return b != 0; } + + private: + int b; +}; + +C a, b, c; +bool d; + +template +void +bar (T) +{ + if (a = b) // { dg-warning "assignment" "correct warning" } + foo (0); + if ((a = b)) + foo (1); + if (a = a) // { dg-warning "assignment" "correct warning" } + foo (2); + if ((a = a)) + foo (3); + if (b = c) // { dg-warning "assignment" "correct warning" } + foo (4); + else + foo (5); + if ((b = c)) + foo (6); + else + foo (7); + if (b = b) // { dg-warning "assignment" "correct warning" } + foo (8); + else + foo (9); + if ((b = b)) + foo (10); + else + foo (11); + while (c = b) // { dg-warning "assignment" "correct warning" } + foo (12); + while ((c = b)) + foo (13); + while (c = c) // { dg-warning "assignment" "correct warning" } + foo (14); + while ((c = c)) + foo (15); + do foo (16); while (a = b); // { dg-warning "assignment" "correct warning" } + do foo (17); while ((a = b)); + do foo (18); while (a = a); // { dg-warning "assignment" "correct warning" } + do foo (19); while ((a = a)); + for (;c = b;) // { dg-warning "assignment" "correct warning" } + foo (20); + for (;(c = b);) + foo (21); + for (;c = c;) // { dg-warning "assignment" "correct warning" } + foo (22); + for (;(c = c);) + foo (23); + d = a = b; // { dg-warning "assignment" "correct warning" } + foo (24); + d = (a = b); + foo (25); + d = a = a; // { dg-warning "assignment" "correct warning" } + foo (26); + d = (a = a); + foo (27); + if (C(a)) + foo (28); +} + +template +bool +bar1 (T) +{ + return a = b; // { dg-warning "assignment" "correct warning" } +} + +template +bool +bar2 (T) +{ + return (a = b); +} + +template +bool +bar3 (T) +{ + return a = a; // { dg-warning "assignment" "correct warning" } +} + +template +bool +bar4 (T) +{ + return (a = a); +} + +template void bar (int); // { dg-message "instantiated" } +template bool bar1 (int); // { dg-message "instantiated" } +template bool bar2 (int); +template bool bar3 (int); // { dg-message "instantiated" } +template bool bar4 (int); -- cgit v1.2.3
