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.c-torture/execute/20000223-1.c | 61 ++++++++++++++++++++++++ 1 file changed, 61 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/20000223-1.c (limited to 'gcc/testsuite/gcc.c-torture/execute/20000223-1.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/20000223-1.c b/gcc/testsuite/gcc.c-torture/execute/20000223-1.c new file mode 100644 index 000000000..db6180b75 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/20000223-1.c @@ -0,0 +1,61 @@ +/* Copyright (C) 2000 Free Software Foundation, Inc. + Contributed by Nathan Sidwell 23 Feb 2000 */ + +/* __alignof__ should never return a non-power of 2 + eg, sizeof(long double) might be 12, but that means it must be alignable + on a 4 byte boundary. */ + +void check (char const *type, int align) +{ + if ((align & -align) != align) + { + abort (); + } +} + +#define QUOTE_(s) #s +#define QUOTE(s) QUOTE_(s) + +#define check(t) check(QUOTE(t), __alignof__(t)) + +// This struct should have an alignment of the lcm of all the types.
