2018-07-18score: Add a FALLTHROUGH comment to kvprintf()Sebastian Huber1-1/+4
This change was added to the FreeBSD version of this function. This was spotted by Coverity Scan.
2017-11-06score: Add _IO_Printf() and _IO_Vprintf()Sebastian Huber1-0/+365
The previous vprintk() implementation had a questionable licence header, lacks support for the 'z' and 'j' format specifiers, is not robust against invalid format specifiers, uses a global variable for output. Replace it with a stripped down version of the FreeBSD kernel kvprintf() function. The new implementation allows a low overhead rtems_snprintf() if necessary. Update #3199. Close #3216.
