From: Chris Metcalf Date: Tue, 30 Dec 2014 19:11:13 +0000 (-0500) Subject: Fix some warnings in the absence of FP round/exception support X-Git-Tag: glibc-2.21~132 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1ff950ad20111b591ad1312df4d802de9d1f1b1e;p=platform%2Fupstream%2Fglibc.git Fix some warnings in the absence of FP round/exception support Due to tile missing a bunch of FP exception and rounding support, the tests generate warnings. These changes fix the warnings by just not compiling some unused functions, and adding some attribute ((unused)) tags. --- diff --git a/ChangeLog b/ChangeLog index 5780c3a..d6c2d28 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,17 @@ +2014-12-30 Chris Metcalf + + * math/test-fenv.c (test_single_exception, set_single_exc, + feenv_nomask_test, feenv_mask_test, feexcp_nomask_test, + feexcp_mask_test, feenable_test, fe_single_test): Add + [!FE_ALL_EXCEPT] test so these routines are not compiled in the + case where they are not used. + * math/libm-test.inc: Likewise. + * setjmp/test-setjmp-fp.c: Mark attribute ((unused)) on variable + unused in the absence of FP rounding/exception support. + * stdio-common/tst-printf-round.c: Likewise. + * stdlib/tst-strtod-round.c: Likewise. + * stdlib/tst-strtod-underflow.c: Likewise. + 2014-12-30 Joseph Myers [BZ #17723] diff --git a/math/libm-test.inc b/math/libm-test.inc index f86a4fa..b44b2db 100644 --- a/math/libm-test.inc +++ b/math/libm-test.inc @@ -590,6 +590,7 @@ print_complex_max_error (const char *func_name) } +#if FE_ALL_EXCEPT /* Test whether a given exception was raised. */ static void test_single_exception (const char *test_name, @@ -598,7 +599,7 @@ test_single_exception (const char *test_name, int fe_flag, const char *flag_name) { -#ifndef TEST_INLINE +# ifndef TEST_INLINE int ok = 1; if (exception & exc_flag) { @@ -634,9 +635,9 @@ test_single_exception (const char *test_name, if (!ok) ++noErrors; -#endif +# endif } - +#endif /* Test whether exceptions given by EXCEPTION are raised.
