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.

#include <math-svid-compat.h>
Use libm_alias_double in math/. This patch converts libm function implementations in math/ from using weak_alias to using libm_alias_double to define public function names, in cases where it would be appropriate to define _Float64 / _Float32x aliases for those functions as well. This eliminates many NO_LONG_DOUBLE conditionals and ldbl-opt wrappers round these function implementations. Tested for x86_64. Also tested with build-many-glibcs.py. Binary differences seen are that the different order in which remainder and drem symbols get defined as a result of this patch (the same source file defines the same aliases, but in a different order of definition) changes the order of symbols in the final libm.so when long double = double, and for ldbl-opt configurations, the compat symbols for Bessel functions were previously defined by e.g. "compat_symbol (libm, j0, j0l, GLIBC_2_0)", which declares j0l as a compat symbol based on j0 and so makes j0l weak because j0 is weak, and are now defined (indirectly via the relevant macros) based on e.g. __j0, so are no longer weak because __j0 isn't weak. * math/s_fma.c: Include <libm-alias-double.h>.

#include <libm-alias-double.h>
Remove the error handling wrapper from exp and exp2 Introduce new exp and exp2 symbol version that don't do SVID compatible error handling. The standard errno and fp exception based error handling is inline in the new code and does not have significant overhead. The double precision wrappers are disabled for sysdeps/ieee754/dbl-64 by using empty w_exp.c and w_exp2.c files, the math/w_exp.c and math/w_exp2.c files use the wrapper template and can be included by targets that have their own exp and exp2 implementations or use ifunc on the glibc internal __ieee754_exp symbol. The compatibility symbol versions still use the wrapper with SVID error handling around the new code. There is no new symbol version nor compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv). On targets where previously expl and exp2l were aliases of exp and exp2, now they point to the compatibility symbols with the wrapper, because they still need the SVID compatible error handling. This affects NO_LONG_DOUBLE (e.g arm) and LONG_DOUBLE_COMPAT (e.g. alpha) targets as well. The _finite symbols are now aliases of the standard symbols (they have no performance advantage anymore). Both the standard symbols and _finite symbols set errno and thus not const functions. The ia64 asm is changed so the compat and new symbol versions map to the same address. On x86_64 #include <math.h> was added before macro definitions that may affect that header (the new macro name is __exp instead of __ieee754_exp which breaks some math.h macros).

The standard errno and fp exception based error handling is inline in the new code and does not have significant overhead. The double precision wrappers are disabled for sysdeps/ieee754/dbl-64 by using empty w_exp.c and w_exp2.c files, the math/w_exp.c and math/w_exp2.c files use the wrapper template and can be included by targets that have their own exp and exp2 implementations or use ifunc on the glibc internal __ieee754_exp symbol. The compatibility symbol versions still use the wrapper with SVID error handling around the new code. There is no new symbol version nor compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv). On targets where previously expl and exp2l were aliases of exp and exp2, now they point to the compatibility symbols with the wrapper, because they still need the SVID compatible error handling. This affects NO_LONG_DOUBLE (e.g arm) and LONG_DOUBLE_COMPAT (e.g. alpha) targets as well. The _finite symbols are now aliases of the standard symbols (they have no performance advantage anymore). Both the standard symbols and _finite symbols set errno and thus not const functions. The ia64 asm is changed so the compat and new symbol versions map to the same address. On x86_64 #include <math.h> was added before macro definitions that may affect that header (the new macro name is __exp instead of __ieee754_exp which breaks some math.h macros).

Sun Sep 29 12:55:58 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/syscalls.list: Change funciton name for _llseek to _llseek (not llseek). Reported by Matthias Urlichs <smurf@smurf.noris.de>. Sun Sep 29 05:34:32 1996 Ulrich Drepper <drepper@cygnus.com> * inet/rcmd.c: Remove definition of MIN.
