Obsolete matherr, _LIB_VERSION, libieee.a. This patch obsoletes support for SVID libm error handling (the system where a user-defined function matherr is called on a libm function error; only enabled if you also set _LIB_VERSION = _SVID_ or _LIB_VERSION = _XOPEN_) and the use of the _LIB_VERSION global variable to control libm error handling. matherr and _LIB_VERSION are made into compat symbols, not supported for new ports or for static linking. The libieee.a object file (which sets _LIB_VERSION = _IEEE_, so disabling errno setting for some functions) is also removed, and all the related definitions are removed from math.h. The manual already recommends against using matherr, and it's already not supported for _Float128 functions (those use new wrappers that don't support matherr, only errno) - this patch means that it becomes possible to e.g. add sinf32 as an alias to sinf without that resulting in undesired matherr support in sinf32 for existing glibc ports. matherr support is not part of any standard supported by glibc (it was removed in XPG4). Because matherr is a function to be defined by the user, of course user programs defining such a function will still continue to link; it just quietly won't be used. If they try to write to the library's copy of _LIB_VERSION to enable SVID error handling, however, they will get a link error (but if they define their own _LIB_VERSION variable, they won't). I expect the most likely case of build failures from this patch to be programs with unconditional cargo-culted uses of -lieee (based on a notion of "I want IEEE floating point", not any actual requirement for that library). Ideally, the new-port-or-static-linking case would use the new wrappers used for _Float128. This is not implemented in this patch, because of the complication of architecture-specific (powerpc32 and sparc) sqrt wrappers that use _LIB_VERSION and __kernel_standard directly. Thus, the old wrappers and __kernel_standard are still built unconditionally, and _LIB_VERSION still exists in static libm. But when the old wrappers and __kernel_standard are built in the non-compat case, _LIB_VERSION and matherr are defined as macros so code to support those features isn't actually built into static libm or new ports' shared libm after this patch. I intend to move to the new wrappers for static libm and new ports in followup patches. I believe the sqrt wrappers for powerpc32 and sparc can reasonably be removed. GCC already optimizes the normal case of sqrt by generating code that uses a hardware instruction and only calls the sqrt function if the argument was negative (if -fno-math-errno, of course, it just uses the hardware instruction without any check for negative argument being needed). Thus those wrappers will only actually get called in the case of negative arguments, which is not a case it makes sense to optimize for. But even without removing the powerpc32 and sparc wrappers it should still be possible to move to the new wrappers for static libm and new ports, just without having those dubious architecture-specific optimizations in static libm. Everything said about matherr equally applies to matherrf and matherrl (IA64-specific, undocumented), except that the structure of IA64 libm means it won't be converted to using the new wrappers (it doesn't use the old ones either, but its own error-handling code instead). As with other tests of compat symbols, I expect test-matherr and test-matherr-2 to need to become appropriately conditional once we have a system for disabling such tests for ports too new to have the relevant symbols.

Prefer new libm function wrappers for !LIBM_SVID_COMPAT. The initial obsoletion of SVID libm error handling left the old wrappers and __kernel_standard still being used for new ports and static linking, just with macro definitions of _LIB_VERSION and matherr that meant symbols with those names were never actually used and the code for different error handling variants could be optimized out. This patch cleans things up further by eliminating the __kernel_standard use for new ports and static linking. Now, the old wrappers no longer generate any code in the !LIBM_SVID_COMPAT case, while the new errno-only wrappers that were added for float128 support are now also used for float, double and long double in that case. The changes are generally straightforward. The w_scalb*_compat wrappers continue to be used (scalb is obsolescent in the sense of not being supported for float128, but is present in supported standards - the 2001 edition of POSIX and earlier XSI versions - so remains supported for static linking and new ports, as do the float and long double variants that are existing GNU extensions). Those wrappers would only call __kernel_standard in the _LIB_VERSION == _SVID_ case. Since we would like to be able to compile most of glibc without optimization, relying on a static function whose only use is under an if (0) condition being optimized away to avoid an undefined __kernel_standard reference may not be a good idea. Thus, the relevant code in the scalb wrappers has LIBM_SVID_COMPAT conditionals added to guarantee it's not built at all in the case where __kernel_standard does not exist. Just as i386 has its own w_sqrt_compat.c, so w_sqrt.c is also added. ia64 gets dummy w_*.c to prevent those files being built where they would conflict with the ia64 libm, as with its existing w_*_compat.c. Conditions disabling code for !LIBM_SVID_COMPAT are needed in both the math/ wrappers and in the long double wrappers in ldbl-opt (to avoid them setting up aliases and symbol versions for undefined symbols). I hope that future cleanups to how libm function aliases and symbol versioning are done will eliminate the need for most of the ldbl-opt wrappers.
