Carlos O'Donell [Wed, 2 Jul 2014 03:52:09 +0000 (23:52 -0400)]
hppa: Add ABI baselines.

The following ABI baselines were tested against several old releases
of debian and gentoo. Several problems were discovered and fixed as
part of developing the ABI baselines.

Firstly, libBrokenLocale on gentoo exports __ctype_get_mb_cur_max
as @@GLIBC_2.0, but it should be @@GLIBC_2.2 since that's the minimum
version defined in shlib-versions for hppa. I don't know when this
broke, but master properly parses hppa's shlib-versions which clearly
lists libBrokenLocale as defaulting to GLIBC_2.2. Therefore I'm
accepting GLBIC_2.2 as the correct version for this symbol and setting
the baseline to that, despite the fact that the present distribution
is wrong. I don't expect that any new applications should be using
libBrokenLocale, so it should match the oldest behaviour which is to
export a GLIBC_2.2 symbol. For example in debian's 2.7 has it at
version GLIBC_2.2.

Secondly, aio_cancel and aio_cancel64 previously had a compat symbol
at version @GLIBC_2.1 with a new symbol at @@GLIBC_2.3[1]. During the
Linuxthreads to NPTL transition the file aio_cancel.c was lost for hppa
and that resulted in just @@GLIBC_2.1 versions of these symbols being
exported. The @@GLIBC_2.1 version works correctly and uses the right
value of ECANCELLED. Therefore if I were to fix this today it might
break correctly working applications using aio_cancel*@GLIBC_2.1 by
causing those to use the old aio_cancel that used the older value
of ECANCELLED. Thus the best option is to accept that the ABI changed
and ignore older applications in favour of newer applications. The
best thing to do is cleanup the version files (included in the patch).

The rest of the ABI was as expected (ignoring __p_type_syms size
change in 2008).

the same variable name, with an argument involving the variable in the
outer macro.  The fix was to rename the local variables so their names
included the containing macro name, to ensure uniqueness.

I noted then that this would make sense more systematically for all
variables in any soft-fp macro.  Since then, I've used such variable
names in new soft-fp macros.  This patch now converts existing macros
in extended.h and op-common.h to use this convention.  (op-[1248].h
are intended to be converted separately.)

modes added by my patch for bug 16315, but isn't actually limited to
non-default rounding modes: rather, when rounding to nearest the
wrappers produced a result with the correct sign and so always hid the
bug unless -lieee was used to disable the wrappers.  The problem is
that in the cases where Y is large enough that the result overflows or
underflows for X not very close to 1, but not large enough to overflow
or underflow for all X != +/- 1 (in the latter case Y is always an
even integer), a positive overflowing / underflowing result is always
returned, rather than one with the correct sign.  This patch moves the
relevant part of computation of the sign earlier and returns a result
of the correct sign.

Tested for mips64.

[BZ #17097]
* sysdeps/ieee754/ldbl-128/e_powl.c (__ieee754_powl): Return
result with correct sign in case of exponents that produce
overflow except for X very close to 1.

    mktime: merge #if/#ifdef usage from glibc

    * lib/mktime.c: Use "#if defined DEBUG && DEBUG", not "#if DEBUG",
    as that works with both Glibc's and Gnulib's style.
