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/gnat.dg/scalar_mode_agg_compare.adb | 25 +++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 gcc/testsuite/gnat.dg/scalar_mode_agg_compare.adb (limited to 'gcc/testsuite/gnat.dg/scalar_mode_agg_compare.adb') diff --git a/gcc/testsuite/gnat.dg/scalar_mode_agg_compare.adb b/gcc/testsuite/gnat.dg/scalar_mode_agg_compare.adb new file mode 100644 index 000000000..ff3734642 --- /dev/null +++ b/gcc/testsuite/gnat.dg/scalar_mode_agg_compare.adb @@ -0,0 +1,25 @@ +-- { dg-do run } + +procedure Scalar_Mode_Agg_Compare is + + type Point is record + Mapped : Boolean; + Tag : String (1 .. 2); -- HImode + end record; + pragma Pack (Point); -- Tag possibly at bitpos 1 + + function My_Point return Point is + begin + return (Mapped => True, Tag => "XX"); + end; + + A, B : Point := My_Point; +begin + -- The comparison below should find the two Tag fields equal and not + -- attempt to take their address, which might not be byte aligned. + + if A.Tag /= B.Tag then + raise Program_Error; + end if; +end; + -- cgit v1.2.3
