(The two functions are defined to be identical, but ldexp() lives in libc for backwards compatibility.) The old ldexp() implementation... - was more complicated than this one - set errno instead of raising FP exceptions - got some corner cases wrong (e.g. ldexp(1.0, 2000) in round-to-zero mode) The new implementation lives in libc/gen instead of libc/$MACHINE_ARCH/gen, since we don't need N copies of a machine-independent file. The amd64 and i386 platforms retain their fast and correct MD implementations and override this one. Use the RET macro. 2004-11-09T16:49:14Z Olivier Houchard cognet@FreeBSD.org 2004-11-09T16:49:14Z urn:sha1:31489a9a2653e123121e8ca39b4be802013d2b50 For setjmp() and longjmp(), put the signal mask where it's supposed to be, instead of in the space reserved for fp regs. Add a week alias __siglongjmp => siglongjmp. 2004-11-09T16:44:57Z Olivier Houchard cognet@FreeBSD.org 2004-11-09T16:44:57Z urn:sha1:904e5ace47a075cde32d15f96bf79fa40dca84b7 Don't define SOFTFLOAT directly in source files, it's now done in the Makefile. 2004-11-05T23:53:54Z Olivier Houchard cognet@FreeBSD.org 2004-11-05T23:53:54Z urn:sha1:5911b520278d793b939fb365d1e0900b3dcf5179 Fix signalcontext and makecontext. 2004-11-05T23:53:02Z Olivier Houchard cognet@FreeBSD.org 2004-11-05T23:53:02Z urn:sha1:60497154c8c934f314c88922d333720dfbc642b6 Make setjmp()/longjmp() use sigprocmask. 2004-09-23T23:13:46Z Olivier Houchard cognet@FreeBSD.org 2004-09-23T23:13:46Z urn:sha1:3d90a3cd916f390e50ea5f9f5b1f455785060965 Add a dummy set_tp(). 2004-09-23T23:12:57Z Olivier Houchard cognet@FreeBSD.org 2004-09-23T23:12:57Z urn:sha1:05a07e2bda67c84bb5ce60c90bc194e7ab9ab655 Replace seven nominally MD implementations of frexp() that are broken 2004-07-18T21:23:39Z David Schultz das@FreeBSD.org 2004-07-18T21:23:39Z urn:sha1:39bcea8689cb7cd9a708fdc5dbf616939161e5e5 for subnormals with one implementation that works.

This is a lose in the sense that we need a total of 12 functions, but it is necessary for binary compatibility because we have never bumped libm's major version number. In particular, isinf(), isnan(), and isnanf() were BSD libc functions before they were C99 macros, so we can't reimplement them in terms of fpclassify() without adding a dependency on libc.so.5. I have tried to arrange things so that programs that could be compiled in FreeBSD 4.X will generate the same external references when compiled in 5.X. At the same time, the new macros should remain C99-compliant. The isinf() and isnan() functions remain in libc for historical reasons; however, I have moved the functions that implement the macros isfinite() and isnormal() to libm where they belong. Moreover, half a dozen MD versions of isinf() and isnan() have been replaced with MI versions that work equally well.
