This patch fixes bugs in ldbl-128ibm frexpl for 32-bit systems shown
up by warnings:
../sysdeps/ieee754/ldbl-128ibm/s_frexpl.c:82:4: warning: left shift count >= width of type
../sysdeps/ieee754/ldbl-128ibm/s_frexpl.c:129:5: warning: left shift count >= width of type
This did in fact show up in test-ldouble.out (alongside all the other
problems there ... maybe we should again consider running the libm
tests at finer granularity from the makefiles) as already covered by
the testsuite after the previous patch that fixed these bugs for
64-bit systems. The fix is simply using 1LL instead of 1L when
shifting by 52.
Tested for powerpc32 (soft float).
[BZ #16619]
[BZ #16740]
* sysdeps/ieee754/ldbl-128ibm/s_frexpl.c (__frexpl): Use 1LL << 52
instead of 1L << 52.
