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/renaming5.adb | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 gcc/testsuite/gnat.dg/renaming5.adb (limited to 'gcc/testsuite/gnat.dg/renaming5.adb') diff --git a/gcc/testsuite/gnat.dg/renaming5.adb b/gcc/testsuite/gnat.dg/renaming5.adb new file mode 100644 index 000000000..25374fe89 --- /dev/null +++ b/gcc/testsuite/gnat.dg/renaming5.adb @@ -0,0 +1,30 @@ +-- PR ada/46192 +-- Testcase by Rolf Ebert + +-- { dg-do compile } +-- { dg-options "-O2 -fdump-tree-optimized" } + +with System; use System; + +package body Renaming5 is + + type Bits_In_Byte is array (0 .. 7) of Boolean; + pragma Pack (Bits_In_Byte); + + A : Bits_In_Byte; + for A'Address use System'To_Address(16#c0#); + pragma Volatile (A); + + B : Bits_In_Byte renames A; + + procedure Proc is + begin + while B (0) = False loop + null; + end loop; + end; + +end Renaming5; + +-- { dg-final { scan-tree-dump-times "goto" 2 "optimized" } } +-- { dg-final { cleanup-tree-dump "optimized" } } -- cgit v1.2.3
