Author: ngie Date: Wed Dec 16 09:11:11 2015 New Revision: 292328 URL: https://svnweb.freebsd.org/changeset/base/292328 Log: Integrate a number of testcases from tools/regression/lib/msun into the FreeBSD test suite There's no functional change with these testcases; they're purposely being left in TAP format for the time being Other testcases which crash on amd64/i386 as-is have not been integrated yet (they need to be retested on a later version of CURRENT, as I haven't used i386 in some time) MFC after: 3 weeks Sponsored by: EMC / Isilon Storage Division Added: head/lib/msun/tests/cexp_test.c - copied unchanged from r292327, head/tools/regression/lib/msun/test-cexp.c head/lib/msun/tests/conj_test.c - copied unchanged from r292327, head/tools/regression/lib/msun/test-conj.c head/lib/msun/tests/csqrt_test.c - copied unchanged from r292327, head/tools/regression/lib/msun/test-csqrt.c head/lib/msun/tests/fenv_test.c - copied unchanged from r292327, head/tools/regression/lib/msun/test-fenv.c head/lib/msun/tests/fmaxmin_test.c - copied unchanged from r292327, head/tools/regression/lib/msun/test-fmaxmin.c head/lib/msun/tests/ilogb_test.c - copied unchanged from r292327, head/tools/regression/lib/msun/test-ilogb.c head/lib/msun/tests/invctrig_test.c - copied unchanged from r292327, head/tools/regression/lib/msun/test-invctrig.c head/lib/msun/tests/logarithm_test.c - copied unchanged from r292327, head/tools/regression/lib/msun/test-logarithm.c head/lib/msun/tests/lrint_test.c - copied unchanged from r292327, head/tools/regression/lib/msun/test-lrint.c head/lib/msun/tests/nan_test.c - copied unchanged from r292327, head/tools/regression/lib/msun/test-nan.c head/lib/msun/tests/nearbyint_test.c - copied unchanged from r292327, head/tools/regression/lib/msun/test-nearbyint.c head/lib/msun/tests/next_test.c - copied unchanged from r292327, head/tools/regression/lib/msun/test-next.c head/lib/msun/tests/rem_test.c - copied unchanged from r292327, head/tools/regression/lib/msun/test-rem.c head/lib/msun/tests/trig_test.c - copied unchanged from r292327, head/tools/regression/lib/msun/test-trig.c Deleted: head/tools/regression/lib/msun/test-cexp.c head/tools/regression/lib/msun/test-cexp.t head/tools/regression/lib/msun/test-conj.c head/tools/regression/lib/msun/test-conj.t head/tools/regression/lib/msun/test-csqrt.c head/tools/regression/lib/msun/test-csqrt.t head/tools/regression/lib/msun/test-fenv.c head/tools/regression/lib/msun/test-fenv.t head/tools/regression/lib/msun/test-fmaxmin.c head/tools/regression/lib/msun/test-fmaxmin.t head/tools/regression/lib/msun/test-ilogb.c head/tools/regression/lib/msun/test-ilogb.t head/tools/regression/lib/msun/test-invctrig.c head/tools/regression/lib/msun/test-logarithm.c head/tools/regression/lib/msun/test-logarithm.t head/tools/regression/lib/msun/test-lrint.c head/tools/regression/lib/msun/test-lrint.t head/tools/regression/lib/msun/test-nan.c head/tools/regression/lib/msun/test-nan.t head/tools/regression/lib/msun/test-nearbyint.c head/tools/regression/lib/msun/test-nearbyint.t head/tools/regression/lib/msun/test-next.c head/tools/regression/lib/msun/test-next.t head/tools/regression/lib/msun/test-rem.c head/tools/regression/lib/msun/test-rem.t head/tools/regression/lib/msun/test-trig.c head/tools/regression/lib/msun/test-trig.t Modified: head/lib/msun/tests/Makefile head/tools/regression/lib/msun/Makefile Modified: head/lib/msun/tests/Makefile ============================================================================== --- head/lib/msun/tests/Makefile Wed Dec 16 08:53:24 2015 (r292327) +++ head/lib/msun/tests/Makefile Wed Dec 16 09:11:11 2015 (r292328) @@ -36,11 +36,34 @@ NETBSD_ATF_TESTS_C+= sqrt_test NETBSD_ATF_TESTS_C+= tan_test NETBSD_ATF_TESTS_C+= tanh_test +TAP_TESTS_C+= cexp_test +TAP_TESTS_C+= conj_test +TAP_TESTS_C+= csqrt_test +TAP_TESTS_C+= fenv_test +TAP_TESTS_C+= fmaxmin_test +TAP_TESTS_C+= ilogb_test +TAP_TESTS_C+= invctrig_test +TAP_TESTS_C+= logarithm_test +TAP_TESTS_C+= lrint_test +TAP_TESTS_C+= nan_test +TAP_TESTS_C+= nearbyint_test +TAP_TESTS_C+= next_test +TAP_TESTS_C+= rem_test +TAP_TESTS_C+= trig_test + +.for t in ${TAP_TESTS_C} +CFLAGS.$t+= -O0 +CFLAGS.$t+= -I${SRCTOP}/tools/regression/lib/msun +.endfor + CSTD= c99 -LIBADD+= m #COPTS+= -Wfloat-equal +IGNORE_PRAGMA= + +LIBADD+= m + # Copied from lib/msun/Makefile .if ${MACHINE_CPUARCH} == "i386" ARCH_SUBDIR= i387 Copied: head/lib/msun/tests/cexp_test.c (from r292327, head/tools/regression/lib/msun/test-cexp.c) ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/lib/msun/tests/cexp_test.c Wed Dec 16 09:11:11 2015 (r292328, copy of r292327, head/tools/regression/lib/msun/test-cexp.c) @@ -0,0 +1,322 @@ +/*- + * Copyright (c) 2008-2011 David Schultz <das@FreeBSD.org> + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
