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/pack-test-3.c | 44 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pack-test-3.c (limited to 'gcc/testsuite/gcc.dg/pack-test-3.c') diff --git a/gcc/testsuite/gcc.dg/pack-test-3.c b/gcc/testsuite/gcc.dg/pack-test-3.c new file mode 100644 index 000000000..8b0390378 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pack-test-3.c @@ -0,0 +1,44 @@ +/* { dg-do compile } */ + +/* Copyright (C) 2003 Free Software Foundation, Inc. + Contributed by Nathan Sidwell 15 Jul 2003 */ + +/* you should not be able to pack a typedef to a struct, only the + underlying struct can be packed. */ + +/* ok */ +struct u1 +{ + char field1; + short field2; + int field3; +}; + +/* ok */ +typedef struct p1 { + char field1; + short field2; + int field3; +} __attribute__ ((packed)) p1_t1; + +/* ok */ +typedef struct __attribute__ ((packed)) p2 { + char field1; + short field2; + int field3; +} p2_t1; + +int ary1[sizeof (struct p1) == sizeof (p1_t1) ? 1 : -1]; +int ary2[sizeof (struct p2) == sizeof (p2_t1) ? 1 : -1]; +int ary3[sizeof (struct p1) == sizeof (struct p2) ? 1 : -1]; + +/* not ok */ +typedef struct u1 __attribute__ ((packed)) u1_t1; /* { dg-warning "attribute ignored" "" }*/ +typedef struct u1 u1_t2 __attribute__ ((packed)); /* { dg-warning "attribute ignored" "" }*/ + +typedef struct p3 { + char field1; + short field2; + int field3; +} p3_t1 __attribute__ ((packed)); /* { dg-warning "attribute ignored" "" }*/ + -- cgit v1.2.3
