* libm/Makefile.in: reformat the list of wrappersDenis Vlasenko2009-02-171-17/+120
| | | | | | | | | | | | | | | 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.
* test/math/compile_test.c: "are long double functions even compile/link?" testDenis Vlasenko2009-02-171-2/+2
| | | | | *: fix everything which prevents above from building
* ldouble_wrappers.c: fix __signbitl, it was calling itself by mistake.Denis Vlasenko2009-02-091-1/+1
| | | | | | remove wrong casts to long double of long return values. remove lots of empty lines.

* libm: add scalbf, gammaf, significandf wrappers.Denis Vlasenko2009-02-051-1/+1
| | | | | | This makes in possible to enable test/math (not it compiles, but has lots of test failures).

* libm: remove scalbln implementation, it seems to be less correct than scalbn.Denis Vlasenko2009-01-031-2/+1
