Hi, I've proposed a new implementation of decimal conversion for lib/vsprintf.c; see <http://thread.gmane.org/gmane.linux.kernel/1892035/focus=1905478>. Benchmarking so far shows 25-50% (depending on distribution of input numbers) improvement on x86_64 and 10-30% on various 32 bit platforms.
Since the new code plays a little endianness game I would really appreciate it if someone here would run the test and verification code on ppc. The code is on github, https://github.com/Villemoes/dec, and it should be as simple as git clone https://github.com/Villemoes/dec.git cd dec make ./test # benchmark ./verify # correctness though I can't blame you if you want to inspect the code before compiling and running something some stranger asks you to download :-) See also the README file. If 'make' doesn't work out-of-the-box, I'd also like to hear from you. Thanks, Rasmus _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
