2009-11-14Revert "libm: fix C99_MATH on __NO_LONG_DOUBLE_MATH hosts"Bernhard Reutner-Fischer
This reverts commit 73d6e5c41b61633e22ea74e3aa2df721512dca57. barking up the wrong tree Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2009-11-14libm: fix C99_MATH on __NO_LONG_DOUBLE_MATH hostsBernhard Reutner-Fischer
alias l to their normal double counterparts. Works around problems with libgcc blindly calling __finitel on e.g. ppc32 Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2009-02-17libm/Makefile.in: reformat the list of wrappersDenis Vlasenko
so that it is easier to modify, sort, etc; use __ in filenames of wrappers which wrap __functions (it may be useful to have function and file names ALWAYS match); remove names of not implemented wrappers (it was generating useless empty .o files). libm/ldouble_wrappers.c: comment out the wrapper which is not compiled anyway test/math/compile_test.c: improve this test, it was optimizing out some calls, and we don't want that. No actual code changes.
2009-02-17test/math/compile_test.c: "are long double functions even compile/link?" testDenis Vlasenko
*: fix everything which prevents above from building
2009-02-09ldouble_wrappers.c: fix __signbitl, it was calling itself by mistake.Denis Vlasenko
remove wrong casts to long double of long return values. remove lots of empty lines.

2009-02-05libm: add scalbf, gammaf, significandf wrappers.Denis Vlasenko
This makes in possible to enable test/math (not it compiles, but has lots of test failures).

2009-01-03libm: remove scalbln implementation, it seems to be less correct than scalbn.Denis Vlasenko
instead, either alias scalbln to scalbn if int == long on this arch, or just call scalbn form scalbln. text data bss dec hex filename - 45297 180 4 45481 b1a9 lib/libm.so + 44969 180 4 45153 b061 lib/libm.so

2008-09-26- move libm_hidden_proto to the corresponding headers. Remove from callsites.Bernhard Reutner-Fischer
Note that gamma_r is not provided by glibc, perhaps add a SUN specific knob later

2008-09-25- remove files that are not either LGPL or Public Domain.Bernhard Reutner-Fischer
- pull replacement funcs for fpmacros.c from glibc This removes the powerpc/classic implementation which did not state any license but read: Copyright © 1991 Apple Computer, Inc. All rights reserved. and thus was dubious (and not needed).
2008-06-17- move stripping into do_ar resp compile-m for the sake of simplicityBernhard Reutner-Fischer
2008-06-04- strip the targets and not prerequisitesBernhard Reutner-Fischer
- tidy up PTHREADS_DEBUG_SUPPORT by using per-target STRIP_FLAGS for the few This fixes the spurious rebuilds bernd and vda were seeing with libpthreads.
2008-06-01A slight improvement over my previous commit which ensured we always rebuildBernd Schmidt
libc when one of the source files changes. Since there are more places which want to depend on $(libc), fix them all to use a new variable $(libc.depend), which contains the filename for which we have a rule.
