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/gcc.dg/c90-const-expr-11.c | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/c90-const-expr-11.c (limited to 'gcc/testsuite/gcc.dg/c90-const-expr-11.c') diff --git a/gcc/testsuite/gcc.dg/c90-const-expr-11.c b/gcc/testsuite/gcc.dg/c90-const-expr-11.c new file mode 100644 index 000000000..cfda93e12 --- /dev/null +++ b/gcc/testsuite/gcc.dg/c90-const-expr-11.c @@ -0,0 +1,27 @@ +/* Test for constant expressions: C90 aggregate initializers requiring + constant expressions. */ +/* Origin: Joseph Myers */ +/* { dg-do compile } */ +/* { dg-options "-std=iso9899:1990 -pedantic-errors -O2" } */ + +#include +#include + +double atan(double); + +struct s { double d; }; +struct t { int i; }; + +void +f (void) +{ + /* As in PR 14649 for static initializers. */ + struct s a = { atan (1.0) }; /* { dg-error "is not a constant expression|near initialization" } */ + /* Overflow. */ + struct t b = { INT_MAX + 1 }; /* { dg-warning "integer overflow in expression" } */ + /* { dg-error "overflow in constant expression" "constant" { target *-*-* } 21 } */ + struct t c = { DBL_MAX }; /* { dg-warning "overflow in implicit constant conversion" } */ + /* { dg-error "overflow in constant expression" "constant" { target *-*-* } 23 } */ + /* Bad operator outside sizeof. */ + struct s d = { 1 ? 1.0 : atan (a.d) }; /* { dg-error "is not a constant expression|near initialization" } */ +} -- cgit v1.2.3
