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/abi/bitfield4.C | 41 ++++++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 gcc/testsuite/g++.dg/abi/bitfield4.C (limited to 'gcc/testsuite/g++.dg/abi/bitfield4.C') diff --git a/gcc/testsuite/g++.dg/abi/bitfield4.C b/gcc/testsuite/g++.dg/abi/bitfield4.C new file mode 100644 index 000000000..5434dd973 --- /dev/null +++ b/gcc/testsuite/g++.dg/abi/bitfield4.C @@ -0,0 +1,41 @@ +/* { dg-do run { target { pcc_bitfield_type_matters || default_packed } } } */ + +/* Check bitfields and non-bitfields are aligned & sized similarly. + + Copyright (C) 2002 Free Software Foundation Inc + Contributed by Nathan Sidwell +*/ + +#include +#include + +static int fail; + +#define CHECK1(N, T) do { \ + typedef struct Field_##N { char c; T f; } Field_##N; \ + typedef struct BitField_##N { char c; T f : sizeof (T) * CHAR_BIT; } BitField_##N; \ + if (sizeof (Field_##N) != sizeof (BitField_##N)) { \ + fail = 1; printf ("sizeof %s failed\n", #T); \ + } \ + if (__alignof__ (Field_##N) != __alignof__ (BitField_##N)) { \ + fail = 1; printf ("__alignof__ %s failed\n", #T); \ + } \ +} while (0) + +#define CHECK(N, T) do { \ + CHECK1(N, T); \ + CHECK1 (s##N, signed T); \ + CHECK1 (u##N, unsigned T); \ +} while (0) + +int main () +{ + + CHECK (c, char); + CHECK (s, short); + CHECK (i, int); + CHECK (l, long); + CHECK (ll, long long); + + return fail; +} -- cgit v1.2.3
