* Fixed the threshold for using the simple Taylor approximation.bde2006-07-072-2/+2
| | | | | | | | | | | | | | | | | | | | | In e_log.c, there was just a off-by-1 (1 ulp) error in the comment about the threshold. The precision of the threshold is unimportant, but the magic numbers in the code are easier to understand when the threshold is described precisely. In e_logf.c, mistranslation of the magic numbers gave an off-by-1 (1 * 16 ulps) error in the intended negative bound for the threshold and an off-by-7 (7 * 16 ulps) error in the intended positive bound for the threshold, and the intended bounds were not translated from the double precision bounds so they were unnecessarily small by a factor of about 2048. The optimization of using the simple Taylor approximation for args near a power of 2 is dubious since it only applies to a relatively small proportion of args, but if it is done then doing it 2048 times as often _may_ be more efficient. (My benchmarks show unexplained dependencies on the data that increase with further optimizations in this area.)
* Fixed tanh(-0.0) on ia64 and optimizeed tanh(x) for 2**-55 <= |x| <bde2006-07-051-10/+10
| | | | | | | | | | | | | | | | | | | 2**-28 as a side effect, by merging with the float precision version of tanh() and the double precision version of sinh(). For tiny x, tanh(x) ~= x, and we used the expression x*(one+x) to return this value (x) and set the inexact flag iff x != 0. This doesn't work on ia64 since gcc -O does the dubious optimization x*(one+x) = x+x*x so as to use fma, so the sign of -0.0 was lost. Instead, handle tiny x in the same as sinh(), although this is imperfect: - return x directly and set the inexact flag in a less efficient way. - increased the threshold for non-tinyness from 2**-55 to 2**-28 so that many more cases are optimized than are pessimized. Updated some comments and fixed bugs in others (ranges for half-open intervals mostly had the open end backwards, and there were nearby style bugs).
* Removed the optimized asm versions of scalb() and scalbf(). Thesebde2006-07-053-62/+2
| | | | | | | | | | | | | | | | | | | | | | | | | functions are only for compatibility with obsolete standards. They shouldn't be used, so they shouldn't be optimized. Use the generic versions instead. This fixes scalbf() as a side effect. The optimized asm version left garbage on the FP stack. I fixed the corresponding bug in the optimized asm scalb() and scalbn() in 1996. NetBSD fixed it in scalb(), scalbn() and scalbnf() in 1999 but missed fixing it in scalbf(). Then in 2005 the bug was reimplemented in FreeBSD by importing NetBSD's scalbf(). The generic versions have slightly different error handling: - the asm versions blindly round the second parameter to a (floating point) integer and proceed, while the generic versions return NaN if this rounding changes the value. POSIX permits both behaviours (these functions are XSI extensions and the behaviour for a bogus non-integral second parameter is unspecified). Apart from this and the bug in scalbf(), the behaviour of the generic versions seems to be identical. (I only exhusatively tested generic_scalbf(1.0F, anyfloat) == asm_scalb(1.0F, anyfloat). This covers many representative corner cases involving NaNs and Infs but doesn't test exception flags. The brokenness of scalbf() showed up as weird behaviour after testing just 7 integer cases sequentially.)
* Backed out rev.1.10. It tried to implement ldexpf() as a weak referencebde2006-07-051-2/+0
| | | | | | | | | | | | | | | | | to scalbf(), but ldexpf() cannot be implemented in that way since the types of the second parameter differ. ldexpf() can be implemented as a weak or strong reference to scalbnf() (*) but that was already done long before rev.1.10 was committed. The old implementation uses a reference, so rev.1.10 had no effect on applications. The C files for the scalb() family are not used for amd64 or i386, so rev.1.10 had even less effect for these arches. (*) scalbnf() raises the radix to the given exponent, while ldexpf() raises 2 to the given exponent. Thus the functions are equivalent except possibly for their error handling iff the radix is 2. Standards more or less require identical error handling. Under FreeBSD, the functions are equivalent except for more details being missing in scalbnf()'s man page.
* Use some math tricks in arena_run_reg_dalloc() to avoid actual division, asjasone2006-07-011-83/+90
| | | | | | | | | | | | | | | | | well as avoiding a switch statement. This change has no significant impact to performance when branch prediction is successful at predicting the sizes of objects passed to free(), but in the case that the object sizes are semi-random, this change has the potential to prevent many branch prediction misses, thus improving performance substantially. Take advantage of alignment guarantees in ipalloc(), and pad object sizes to something less than a power of two when possible. This has the potential to substantially reduce internal fragmentation for objects allocated via posix_memalign(). Avoid an unnecessary pow2_ceil() call in arena_ralloc().
