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/unchecked_convert2.adb | 34 ++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) create mode 100644 gcc/testsuite/gnat.dg/unchecked_convert2.adb (limited to 'gcc/testsuite/gnat.dg/unchecked_convert2.adb') diff --git a/gcc/testsuite/gnat.dg/unchecked_convert2.adb b/gcc/testsuite/gnat.dg/unchecked_convert2.adb new file mode 100644 index 000000000..f542af7c3 --- /dev/null +++ b/gcc/testsuite/gnat.dg/unchecked_convert2.adb @@ -0,0 +1,34 @@ +-- { dg-do run } + +with Ada.Unchecked_Conversion; +with Ada.Streams; use Ada.Streams; +with Ada.Text_IO; use Ada.Text_IO; + +procedure Unchecked_Convert2 is + + subtype Day_Number is Integer range 0 .. 31; + + subtype Byte_Array_Of_Integer is Stream_Element_Array + (1 ..
