4d3dd73e57 drivers/net/tun.c: Re-order all TUN/TAP driver state data. Not only was was with wasting memory due to alignement requirements, it was also causing network packet buffers to be improperly aligned causing problems because the network requires 16-bit packet buffer alignment for uint16_t accesses. This alignment problem was discovered by Alan Carvalho de Assis. 2019-02-24 09:43:30 -06:00

94fe5c8349 include/poll.h: Remove un-named union from 'struct pollfd'. It is not required by OpenGroup.org and violates the NuttX C coding standard because it is not C89 compatible. 2019-02-21 17:40:30 -06:00

d7586c27a5 libs/libc/stdio/Kconfig: Add 'range 9 999999' to CONFIG_LIBC_NL_ARGMAX. Per OpenGroup.org, the minimum value for NL_ARGMAX is 9. 2019-02-21 14:04:46 -06:00

533fd0636e libs/libc/lib_libvsprintf.c and Kconfig: Remove CONFIG_LIBC_PRINT_MINIMAL. The output in that configuration is unsatisfactory and inappropriate for use with NuttX. For example, the output from many NSH commands become corrupted and useless. Doesn't belong in this context. 2019-02-21 13:53:34 -06:00

0059a5a88e libs/libc/stdio/lib_vsprintf.c and Kconfig: 
- Numbered arguments now work by using two pass parsing and an argument list.
    The maximum number of numbered args is determined by CONFIG_LIBC_NL_ARGMAX
    which is then copied into NL_ARGMAX.
  - Size of pointer argument ('p') is determined before output.

include/limits.h:  Define NL_ARGMAX (as well as some of the other 'invariant
  values' per http://pubs.opengroup.org/onlinepubs/7908799/xsh/limits.h.html)

146c398eff libs/libc/stdio/lib_libvsprintf.c: Fix typo: PRINTF_LEVEL, not PRINT_LEVEL. 2019-02-20 08:40:27 -06:00
Gregory Nutt
05a68d175b libs/libc/stdio/Kconfig: CONFIG_LIBC_NUMBERED_ARGS now depends on EXPERIMENTAL. Per Johannes: I tested numbered arguments on i.mx rt 1050, and it isn't working. Only on Linux/MSYS 64bit all relevant data types are size 8 bytes, and therefore my loop through the arg list is working. On 32bit systems, all is 4 bytes except floating point variables which is implicit 8 byte double. 2019-02-20 08:00:35 -06:00

432f487581 arch/arm/src/stm32h7 and stm32l4: Apply David Sidrane's fix for the STM32F7 to the STM32L4 and STM32H7. The same change might be appropropriate to STMF0/LO and STM32, but the patch does not apply cleanly. It would have to be manually checked. 2019-02-19 14:47:27 -06:00

e982488e6c include/nuttx/compiler.h: Important fix for C++ users. compiler.h was using the value of __STDC_VERSION__ to determine if inline functions are supported or not. If not then the keyword inline was defined out. Good for C but bad for C++ because C++ does not defined __STDC_VERSION__ at all. C++ applications may draw in compiler.h indirectly via other head files and this can result in C++ compiler problems since 'inline' is defined out. This fix is to ignore the (undefined) __STDC_VERSION__ if __cplusplus is defined. 2019-02-19 09:04:04 -06:00

a76e137ce2 Squashed commit of the following: 
sched/init/nx_start.c:  Add support for CONFIG_BOARD_DRIVER_INITIALIZE.  If this option is selected then nx_start() will call a board-provided function board_driver_initialize() immediately after calling up_initialize().

    Rename CONFIG_BOARD_INITIALIZE to CONFIG_BOARD_LATE_INITIALIZE.

    Raname board_initialize() to board_late_initialize()

76a2f6c2a2 libs/libc/stdio: This commits makes the nano-printf the defualt logic for the printf family. The legacy printf is still available via CONFIG_LIBC_PRINT_LEGACY. This commit also modifies the nano-prinf configure: The PRINT_LEVEL is not long selectable. Instead, a not CONFIG_LIBC_PRINT_MINIMAL boolean setting was added and the PRINT_LEVEL is derived from a combination of CONFIG_LIBC_PRINT_MINIMAL, CONFIG_LIBC_FLOATINGPOINT, and CONFIG_LIBC_LONG_LONG. 2019-02-17 12:29:20 -06:00

Seems to check out, but still risky. libs/libc/stdio/lib_libdtoa.c: A fix for the %g format. The algorithm will sometimes generate number greater than the precision of type double. This adds a check if the precision has been exceeded and logic to remove the least significant garbage. 2019-02-16 18:08:38 -06:00

653ff2c34e Restore lib_sprintf(). It was removed because I thought was not used. But I was wrong; there is logic in drivers/syslog that depends on lib_sprintf(). 
This commits reverts a part of commit c271151d57.  That commit also removed lib_sscanf() which really is not needed.

38e93ede2b Revert "libs/libc/stdio: Fix the %f floating point output format." 
The previous implementation was probably corect.  On Cygwin with GCC I see this:

int main(int argc, char **argv)
{
  printf("Value 1.2 is: [%f]\n", 1.2);
  printf("Value 0.1 is: [%f]\n", 0.1);
  printf("Value 0.0: [%f]\n", 0.0);
  printf("Value 347.6872: [%f]\n", 347.6872);
}

Generates output

Value 1.2 is: [1.200000]
Value 0.1 is: [0.100000]
Value 0.0: [0.000000]
Value 347.6872: [347.687200]

This reverts commit eb0223bc7f.
