a8a66667c1 libc: Fix ARMv7-A/R memcpy assembly. 2017-01-20 13:33:50 -06:00
Gregory Nutt
be5ba90d4f Move optimized ARM memcpy functions from arch/arm/src/ to libc/machine/. This is necessary for the PROTECTED and KERNEL build modes. Otherwise, memcpy() will be built in to kernel space and not accessible to applications. 2017-01-20 10:53:46 -06:00

c83da3c48f Remove minnsh configurations and support logic: up_getc() and lowinstream. 
This was an interesting exercise to see just how small you could get NuttX, but otherwise it was not useful:  (1) the NSH code violated the OS interface layer by callup up_getc and up_putc directly, and (2) while waiting for character input, NSH would call up_getc() which would hog all of the CPU.  NOt a reasonably solution other than as a proof of concept.

123c520db4 Correct time initialization for the case where time is initialized from settings in the .config file. The correct range for month (tm_mon) internally is 0-11, not 1-12 as it is in the .config file. 2016-10-27 08:36:24 -06:00

57ad019fba Revert "Correct a problem in clock_gettime(CLOCK_REALTIME, &time); which is ahead by 1 month of the specified CONFIG_START_MONTH" 
I don't believe this change is correct in general.  Nomralling clock_isleapyear() is called with tm_mon which is in the range of 0-11.  That change would be bad for that range.  It would make sense for a range of 1-12, but that is not how tm_mon is defined.

This reverts commit 1796a25e53.
