2016-12-16Make w_scalbln type-genericGabriel F. T. Gomes
This patch converts the wrapper scalbln (which set errno directly rather than doing anything with __kernel_standard) to use the type-generic template machinery, in the same way that has been done for ldexp. Tested for powerpc64le, s390, and x86_64.
2016-06-08Fix ldexp, scalbn, scalbln for sNaN input (bug 20225).Joseph Myers
The wrapper implementations of ldexp / scalbn / scalbln (architecture-independent), and their float / long double variants, return sNaN for sNaN input. This patch fixes them to add relevant arguments to themselves so that qNaN is returned in this case. Tested for x86_64 and x86. [BZ #20225] * math/s_ldexp.c (__ldexp): Add non-finite or zero argument to itself. * math/s_ldexpf.c (__ldexpf): Likewise. * math/s_ldexpl.c (__ldexpl): Likewise. * math/w_scalbln.c (__w_scalbln): Likewise. * math/w_scalblnf.c (__w_scalblnf): Likewise. * math/w_scalblnl.c (__w_scalblnl): Likewise. * math/libm-test.inc (scalbn_test_data): Add sNaN tests. (scalbln_test_data): Likewise.

to use standard C99 macros. This has no effect on generated code.

2014-06-20[BZ #6803] Set errno for scalbln, scalbnStefan Liebler
Errno is not set and the testcases will fail. Now the scalbln-aliases are removed in i386/m68 and the wrappers are used when calling the scalbln-functions. On ia64 only scalblnf has its own implementation. For scalbln and scalblnl the ieee754/dbl-64 and ieee754/ldbl-96 are used, thus the wrappers are needed, too.
