Bug #: 52388
Summary: binutils-2.21 and newer break ACATS on
arm-linux-gnueabi due to widechr compile failure
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: mi...@it.uu.se
On armv5tel-linux-gnueabi, if I let PATH refer to binutils-2.21 or newer, then
the ACATS test suite disappears from the final summary report. Inspecting
gcc/testsuite/ada/acats/acats.log shows
...
splitting /mnt/scratch/objdir46/gcc/testsuite/ada/acats/support/impdefh.a into:
impdef-annex_h.ads
splitting /mnt/scratch/objdir46/gcc/testsuite/ada/acats/support/widechr.a into:
widechr.adb
**** Failed to compile widechr
and nothing else.
This happens with every gcc branch (4.4 -> 4.7), and binutils-2.21, 2.22, and
cvs head as of early December 2011. Reverting to binutils-2.20.1 eliminates
the above error and gives me clean ACATS results. The "gnat" test results look
the same regardless of the binutils version.
I have traced the regression to one specific change in binutils
(http://sourceware.org/ml/binutils/2010-05/msg00074.html), commited as part of
a group of changes
(http://sourceware.org/ml/binutils-cvs/2010-05/msg00035.html), but I don't see
anything obviously wrong with it.
Before I report this to the sourceware bugzilla, is there any way to get a
better error diagnostic from the widechr compilation attempt?
