2012-05-17	math: support platforms with limited FP rounding or exception support	Chris Metcalf	5	-0/+40
	For some tests, just claim that fetestexcept() always returns true, so the rest of the test can be compiled. For libm-test, provide known bogus values for unsupported rounding modes, so fesetround() will return failure. Elsewhere, just add some #ifdefs to avoid code that uses particular FP exceptions if the exceptions aren't supported.
2012-05-10	Add a missing #include.	Roland McGrath	1	-0/+1

2012-05-10	Fix for logb/logbf/logbl (bugs 13954/13955/13956)	Adhemerval Zanella	1	-0/+16
	POSIX 2008 states that if the input for 'logb[f\|l]' is a subnormal number it should be treated as if it were normalized. This means the implementation should calculate the log2 of the mantissa and add it to the subnormal exponent (-126 for float and -1022 for double and IBM long double). This patch takes care of that.

2012-05-02	Use -frounding-math for math testsuite	Andreas Jaeger	1	-6/+8
	We should tell GCC that we manipulate the rounding mode and therefore add -frounding-math to these files that call fesetround.

2012-04-17	Fix ilogb exception and errno (bug 6794)	Adhemerval Zanella	5	-8/+136
	[BZ #6794] Following Joseph comments about bug 6794, here is a proposed fix. It turned out to be a large fix mainly because I had to move some file along to follow libm files/names conventions. Basically I have added wrappers (w_ilogb.c, w_ilogbf.c, w_ilogbl.c) that now calls the symbol '__ieee754_ilogb'. The wrappers checks for '__ieee754_ilogb' output and set the errno and raise exceptions as expected. The '__ieee754_ilogb' is implemented in sysdeps. I have moved the 's_ilogb[f\|l]' files to e_ilogb[f\|l] and renamed the '__ilogb[f\|l]' to '__ieee754_ilogb[f\|l]'. I also found out a bug in i386 and x86-64 assembly coded ilogb implementation where it raises a FE_DIVBYZERO when argument is '0.0'. I corrected this issue as well. Finally I added the errno and FE_INVALID tests for 0.0, NaN and +-InF argument. Tested on i386, x86-64, ppc32 and ppc64.
