Re: [PATCH] Recent libm additions
Version 2. After applying the patch, one can
% svn delete libm/msun/src/polevll.c
% svn commit libm/msun/src/polevll.c
* lib/msun/Makefile:
. Remove polevll.c
* lib/msun/ld80/e_powl.c:
. Copy contents of polevll.c to here. This is the only consumer of
these functions. Make functions 'static inline'.
. Make reducl a 'static inline' function.
* lib/msun/man/exp.3:
. Remove BUGS section that no longer applies.
* lib/msun/src/math_private.h:
. Remove prototypes of __p1evll() and __polevll()
* lib/msun/src/s_cpow.c:
* lib/msun/src/s_cpowf.c:
* lib/msun/src/s_cpowl.c
. Use the CMPLX macro from either C99 or math_private.h (depends of
compiler support) instead of the problematic use of complex I.

[ toolchain-metadata.mk is missing when kernel-toolchain is used.
I've no clue if this is intentional or not. ]

I probably extended the LLVM_TARGET_ALL=no in cross-compiler too far. I
thought I had left that out for kernel-toolchain but apparently not.
Try this patch and kernel-toolchain after applying please:

Re: [PATCH] Recent libm additions
Julia's libm is https://github.com/JuliaMath/openlibm (or http://openlibm.org/) The do try merging latest from freebsd (msun), although it seems not the very latest. (see e.g. https://github.com/JuliaMath/openlibm/pull/118) I did try installing the master git branch of openlibm on FreeBSD 11.1 with clang, it builds and passes all tests they have. Does it make sense to contribute there more tests (if any --- they seem to have quite a list), to clear suspicions about precision?
