* It is unclear who is wrong and who is right, but when operating onMaxim Sobolev2005-11-301-0/+10
| | | | | | | | | | | | | | | | | | plain file bsdlabel(8) always writes label at a fixed offset from its beginning (512 bytes), regardless of the sector size. At the same time, bsdlabel geom class expects label to be available at the very beginning of the second sector. As a result, images prepared in userland for media with sector size different from 512 bytes (i.e. 2k for cdroms) are not recognized by the tasting mechanism. Solve the problem by always looking for the label at 512-byte offset if we can't find it at the beginning of the second sector and sector size is not 512 bytes.

* Rearranged the polynomial evaluation to reduce dependencies, as inBruce Evans2005-11-302-9/+13
| | | | | | | | | | | | | | | | | | | | | | | k_tanf.c but with different details. The polynomial is odd with degree 13 for tanf() and odd with degree 9 for sinf(), so the details are not very different for sinf() -- the term with the x**11 and x**13 coefficients goes awaym and (mysteriously) it helps to do the evaluation of w = z*z early although moving it later was a key optimization for tanf(). The details are different but simpler for cosf() because the polynomial is even and of lower degree. On Athlons, for uniformly distributed args in [-2pi, 2pi], this gives an optimization of about 4 cycles (10%) in most cases (13% for sinf() on AXP, but 0% for cosf() with gcc-3.3 -O1 on AXP). The best case (sinf() with gcc-3.4 -O1 -fcaller-saves on A64) now takes 33-39 cycles (was 37-45 cycles). Hardware sinf takes 74-129 cycles. Despite being fine tuned for Athlons, the optimization is even larger on some other arches (about 15% on ia64 (pluto2) and 20% on alpha (beast) with gcc -O2 -fomit-frame-pointer).

* Fixed cosf(x) when x is a "negative" NaNs. I broke this in rev.1.10.Bruce Evans2005-11-301-11/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | cosf(x) is supposed to return something like x when x is a NaN, and we actually fairly consistently return x-x which is normally very like x (on i386 and and it is x if x is a quiet NaN and x with the quiet bit set if x is a signaling NaN. Rev.1.10 broke this by normalising x to fabsf(x). It's not clear if fabsf(x) is should preserve x if x is a NaN, but it actually clears the sign bit, and other parts of the code depended on this. The bugs can be fixed by saving x before normalizing it, and using the saved x only for NaNs, and using uint32_t instead of int32_t for ix so that negative NaNs are not misclassified even if fabsf() doesn't clear their sign bit, but gcc pessimizes the saving very well, especially on Athlon XPs (it generates extra loads and stores, and mixes use of the SSE and i387, and this somehow messes up pipelines). Normalizing x is not a very good optimization anyway, so stop doing it. (It adds latency to the FPU pipelines, but in previous versions it helped except for |x| <= 3pi/4 by simplifying the integer pipelines.) Use the same organization as in s_sinf.c and s_tanf.c with some branches reordered. These changes combined recover most of the performance of the unfixed version on A64 but still lose 10% on AXP with gcc-3.4 -O1 but not with gcc-3.3 -O1. Notes: svn path=/head/; revision=152949

* Fixed the hi+lo approximation to log(2). The normal 17+24 bit decompositionBruce Evans2005-11-301-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | that was used doesn't work normally here, since we want to be able to multiply `hi' by the exponent of x _exactly_, and the exponent of x has more than 7 significant bits for most denormal x's, so the multiplication was not always exact despite a cloned comment claiming that it was. (The comment is correct in the double precision case -- with the normal 33+53 bit decomposition the exponent can have 20 significant bits and the extra bit for denormals is only the 11th.) Fixing this had little or no effect for denormals (I think because more precision is inherently lost for denormals than is lost by roundoff errors in the multiplication). The fix is to reduce the precision of the decomposition to 16+24 bits. Due to 2 bugs in the old deomposition and numerical accidents, reducing the precision actually increased the precision of hi+lo. The old hi+lo had about 39 bits instead of at least 41 like it should have had. There were off-by-1-bit errors in each of hi and lo, apparently due to mistranslation from the double precision hi and lo. The correct 16 bit hi happens to give about 19 bits of precision, so the correct hi+lo gives about 43 bits instead of at least 40. The end result is that expf() is now perfectly rounded (to nearest) except in 52561 cases instead of except in 67027 cases, and the maximum error is 0.5013 ulps instead of 0.5023 ulps.

Robert accidentally changed the snderr() macro to jump to the out label which assumes the lock is already released rather than the release label which drops the lock in his previous change to sosend().

* The DEFAULTS changes caused the user specified config file to be openedPeter Wemm2005-11-291-0/+5
| | | | | | | | | | | | | | | | | | much later than before, and it is now after we do a mkdir ../compile/FILE. As a result, if you do 'config DOESNOTEXIST', it now creates the directory ../config/DOESNOTEXIST. It did not do that before. If DEFAULTS does not exist, it still fails early before any permanent changes. This shameless hack restores the old behavior of ensuring the config file actually exists before mkdiring its counterpart directory. Now I can rmdir ../compile/D and it will stay dead, after my fingers keep sabotaging me with 'config D<tab><enter>'. (Some of my kernel names started with D, which used to be 1-character unique and my fingers knew this very well...) Notes: svn path=/head/; revision=152937
