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/gnu89-const-expr-1.c | 56 +++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/gnu89-const-expr-1.c (limited to 'gcc/testsuite/gcc.dg/gnu89-const-expr-1.c') diff --git a/gcc/testsuite/gcc.dg/gnu89-const-expr-1.c b/gcc/testsuite/gcc.dg/gnu89-const-expr-1.c new file mode 100644 index 000000000..4fd6671a4 --- /dev/null +++ b/gcc/testsuite/gcc.dg/gnu89-const-expr-1.c @@ -0,0 +1,56 @@ +/* Test for constant expressions: GNU extensions. */ +/* Origin: Joseph Myers */ +/* { dg-do compile } */ +/* { dg-options "-std=gnu89 -pedantic-errors" } */ + +int n; + +void +f (void) +{ + int i = 0; + int a[n]; /* { dg-error "ISO C90 forbids variable length array" } */ + enum e1 { + /* Integer constant expressions may not contain statement + expressions (not a permitted operand). */ + E1 = (1 ? 0 : ({ 0; })), /* { dg-error "constant expression" } */ + /* { dg-error "ISO C forbids braced-groups" "ISO" { target *-*-* } 16 } */ + /* Real and imaginary parts act like other arithmetic + operators. */ + E2 = __real__ (1 ? 0 : i++), /* { dg-error "constant expression" } */ + E3 = __real__ 0, + E4 = __imag__ (1 ? 0 : i++), /* { dg-error "constant" } */ + E5 = __imag__ 0, + /* __alignof__ always constant. */ + E6 = __alignof__ (int[n]), /* { dg-error "ISO C90 forbids variable length array" } */ + E7 = __alignof__ (a), + /* __extension__ ignored for constant expression purposes. */ + E8 = __extension__ (1 ? 0 : i++), /* { dg-error "constant expression" } */ + E9 = __extension__ 0, + /* Conditional expressions with omitted arguments act like the + standard type. */ + E10 = (1 ? : i++), /* { dg-error "constant expression" } */ + /* { dg-error "ISO C forbids omitting" "ISO" { target *-*-* } 32 } */ + E11 = (1 ? : 0) /* { dg-error "ISO C forbids omitting" } */ + }; + enum e2 { + /* Complex integer constants may be cast directly to integer + types, but not after further arithmetic on them. */ + F1 = (int) (_Complex int) 2i, /* { dg-error "constant expression" } */ + /* { dg-error "complex" "complex" { target *-*-* } 39 } */ + /* { dg-error "imaginary" "imaginary" { target *-*-* } 39 } */ + F2 = (int) +2i, /* { dg-error "constant expression" } */ + /* { dg-error "imaginary" "ISO" { target *-*-* } 42 } */ + F3 = (int) (1 + 2i), /* { dg-error "constant expression" } */ + /* { dg-error "imaginary" "ISO" { target *-*-* } 44 } */ + F4 = (int) 2i /* { dg-error "imaginary" } */ + }; + static double dr = __real__ (1.0 + 2.0i); + /* { dg-error "imaginary" "ISO" { target *-*-* } 48 } */ + static double di = __imag__ (1.0 + 2.0i); + /* { dg-error "imaginary" "ISO" { target *-*-* } 50 } */ + /* Statement expressions allowed in unevaluated subexpressions in + initializers in gnu99 but not gnu89. */ + static int j = (1 ? 0 : ({ 0; })); /* { dg-error "constant expression" } */ + /* { dg-error "braced" "ISO" { target *-*-* } 54 } */ +} -- cgit v1.2.3
