Description James Antill 2006-06-22 19:42:40 UTC
Description of problem:
 sha256sum, sha512sum etc. are present in upstream development but not in our

Version-Release number of selected component (if applicable):

Additional info:

 I'm including a patch backported from upstream development (the backport was
blessed by the maintainer). It adds the new sha* commands and base64 ... and tests.

5.96-4 building.

Comment 4 Tim Waugh 2006-06-23 08:13:16 UTC
Test cases failed on s390 (but succeeded on ia64).

Comment 7 Jim Meyering 2006-06-23 13:35:14 UTC
It appears to be a bug in gcc/memcpy, since memcpy transforms the first four
bytes of a buffer from 128 to 9223372036854775808 (aka 0x8000000000000000). 
Building with -fno-builtin avoids the problem.  I'll submit a test case shortly.

Comment 8 Jim Meyering 2006-06-23 16:11:10 UTC
Update: a better-controlled experiment suggests that the test failures are due
to a bug in gcc's -O2.  When I compile sha512.c with -O1 and relink, the tests pass.

Comment 9 Jim Meyering 2006-06-23 20:24:20 UTC
FYI, the s390 gcc -O2 problem is being tracked here:

Comment 11 Tim Waugh 2006-06-26 08:04:23 UTC
Thanks for working out the problem!  For the moment I've built coreutils with
-O1 on s390/s390x.
