Update.

1999-10-18  Andreas Jaeger  <aj@suse.de>

	Added improved math testsuite:
	* math/libm-test.inc: New file, contains all tests from
	libm-test.c but in a different form.
	* math/libm-test.c: Removed.
	* sysdeps/generic/libm-test-ulps: New file: Fallback ulps file.
	* math/gen-libm-test.pl: New file: Preprocessor.
	* math/test-double.c: Adopted to new testsuite.
	* math/test-idouble.c: Likewise.
	* math/test-float.c: Likewise.
	* math/test-ifloat.c: Likewise.
	* math/test-ldouble.c: Likewise.
	* math/test-ildoubl.c: Likewise.
	* math/Makefile: Added rules to generate new suite.

-/* Part of testsuite for libm.
-
-   This file has to be included by a master file that defines:
-
-   Makros:
-   FUNC(function): converts general function name (like cos) to
-   name with correct suffix (e.g. cosl or cosf)
-   MATHCONST(x):   like FUNC but for constants (e.g convert 0.0 to 0.0L)
-   MATHTYPE:	   floating point type to test
-   TEST_MSG:	   informal message to be displayed
-   CHOOSE(Clongdouble,Cdouble,Cfloat):
-   chooses one of the parameters as epsilon for testing
-   equality
-   PRINTF_EXPR	   Floating point conversion specification to print a variable
-   of type MATHTYPE with printf.  PRINTF_EXPR just contains
-   the specifier, not the percent and width arguments,
-   e.g. "f".
-   PRINTF_XEXPR	   Like PRINTF_EXPR, but print in hexadecimal format.
- */

-/* This program isn't finished yet.
-   It has tests for:
-   acos, acosh, asin, asinh, atan, atan2, atanh,
-   cbrt, ceil, copysign, cos, cosh, erf, erfc, exp, exp10, exp2, expm1,
-   fabs, fdim, floor, fma, fmax, fmin, fmod, fpclassify,
-   frexp, gamma, hypot,
-   ilogb, isfinite, isinf, isnan, isnormal,
-   isless, islessequal, isgreater, isgreaterequal, islessgreater, isunordered,
-   j0, j1, jn,
-   ldexp, lgamma, log, log10, log1p, log2, logb,
-   modf, nearbyint, nextafter,
-   pow, remainder, remquo, rint, lrint, llrint,
-   round, lround, llround,
-   scalb, scalbn, signbit, sin, sincos, sinh, sqrt, tan, tanh, tgamma, trunc,
-   y0, y1, yn
-
-   and for the following complex math functions:
-   cabs, cacos, cacosh, carg, casin, casinh, catan, catanh,
-   ccos, ccosh, cexp, clog, cpow, csin, csinh, csqrt, ctan, ctanh.
-
-   At the moment the following functions aren't tested:
-   conj, cproj, cimag, creal, drem,
-   significand,
-   nan
-
-   The routines using random variables are still under construction.  I don't
-   like it the way it's working now and will change it.
-
-   Parameter handling is primitive in the moment:
-   --verbose=[0..4] for different levels of output:
-   0: only error count
-   1: basic report on failed tests (default)
-   2: full report on failed tests
-   3: full report on failed and passed tests
-   4: additional report on exceptions
-   -v for full output (equals --verbose=4)
-   -s,--silent outputs only the error count (equals --verbose=0)
- */
-
-/* "Philosophy":
-
-   This suite tests some aspects of the correct implementation of
-   mathematical functions in libm.  Some simple, specific parameters
-   are tested for correctness but there's no exhaustive
-   testing.  Handling of specific inputs (e.g. infinity, not-a-number)
-   is also tested.  Correct handling of exceptions is checked
-   against.  These implemented tests should check all cases that are
-   specified in ISO C 9X.
-
-   Exception testing: At the moment only divide-by-zero and invalid
-   exceptions are tested.  Overflow/underflow and inexact exceptions
-   aren't checked at the moment.
-
-   NaN values: There exist signalling and quiet NaNs.  This implementation
-   only uses signalling NaN as parameter but does not differenciate
-   between the two kinds of NaNs as result.
-
-   Inline functions: Inlining functions should give an improvement in
-   speed - but not in precission.  The inlined functions return
-   reasonable values for a reasonable range of input values.  The
-   result is not necessarily correct for all values and exceptions are
-   not correctly raised in all cases.  Problematic input and return
-   values are infinity, not-a-number and minus zero.  This suite
-   therefore does not check these specific inputs and the exception
-   handling for inlined mathematical functions - just the "reasonable"
-   values are checked.
-
-   Beware: The tests might fail for any of the following reasons:
-   - Tests are wrong
-   - Functions are wrong
-   - Floating Point Unit not working properly
-   - Compiler has errors
-
-   With e.g. gcc 2.7.2.2 the test for cexp fails because of a compiler error.

+
+/* "Philosophy":
+
+   This suite tests some aspects of the correct implementation of
+   mathematical functions in libm.  Some simple, specific parameters
+   are tested for correctness but there's no exhaustive
+   testing.  Handling of specific inputs (e.g. infinity, not-a-number)
+   is also tested.  Correct handling of exceptions is checked
+   against.  These implemented tests should check all cases that are
+   specified in ISO C 9X.
+
+   Exception testing: At the moment only divide-by-zero and invalid
+   exceptions are tested.  Overflow/underflow and inexact exceptions
+   aren't checked at the moment.
+
+   NaN values: There exist signalling and quiet NaNs.  This implementation
+   only uses signalling NaN as parameter but does not differenciate
+   between the two kinds of NaNs as result.
+
+   Inline functions: Inlining functions should give an improvement in
+   speed - but not in precission.  The inlined functions return
+   reasonable values for a reasonable range of input values.  The
+   result is not necessarily correct for all values and exceptions are
+   not correctly raised in all cases.  Problematic input and return
+   values are infinity, not-a-number and minus zero.  This suite
+   therefore does not check these specific inputs and the exception
+   handling for inlined mathematical functions - just the "reasonable"
+   values are checked.
+
+   Beware: The tests might fail for any of the following reasons:
+   - Tests are wrong
+   - Functions are wrong
+   - Floating Point Unit not working properly
+   - Compiler has errors
+
+   With e.g. gcc 2.7.2.2 the test for cexp fails because of a compiler error.
