a8a66667c1 libc: Fix ARMv7-A/R memcpy assembly. 2017-01-20 13:33:50 -06:00

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.

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.

4daa553328 lib_asinl.c edited online with Bitbucket. Add missing # on endif. Noted by David Alessio. 2016-07-31 16:47:25 +00:00
David S. Alessio
c145159c6b This commit fixes the following libc/math issues:
1) asin[f l]() use Newton’s method to converge on a solution. But Newton’s method converges very slowly (> 500,000 iterations) for values of x close to 1.0; and, in the case of asinl(), sometimes fails to converge (loops forever). The attached patch uses an trig identity for values of x > sqrt(2). The resultant functions converge in no more than 5 iterations, 6 for asinl().

2) The NuttX erf[f l]() functions are based on Chebyshev fitting to a good guess. The problem there’s a bug in the implementation that causes the functions to blow up with x near -3.0. This patch fixes that problem. It should be noted that this method returns the error function erf(x) with fractional error less than 1.2E-07 and that’s fine for the float version erff(), but the same method is used for double and long double version which will yield only slightly better precision. This patch doesn't address the issue of lower precision for erf() and erfl().

3) a faster version of copysignf() for floats is included.

28a4ca6713 libc/signal and include/signal.h: Rename sigset() to signal(). sigset() is the System V function; signal() is the obsoleted POSIX name. These seem to be equivalent.

06d83c6261 Introduce support for Atmel toolchain in-flash strings
Atmel toolchain AVR compiler provides a transparent in-flash object support using __flash and __memx symbols. The former indicates to compiler that this is a flash-based object.  The later used with pointer indicates that the referenced object may reside either in flash or in RAM. The compiler automatically makes 32-bit pointer with flag indicating whether referenced object is in flash or RAM and generates code to access either in run-time. Thus, any function that accepts __memx object can transparently work with RAM and flash objects.

For platforms with a Harvard architecture and a very small RAM like AVR this allows to move all constant strings used in trace messages to flash in the instruction address space, releasing resources for other things.

This change introduces IOBJ and IPTR type qualifiers.  The 'I' indicates that the object may like in instruction space on a Harvard architecture machine.

For platforms that do not have __flash and __memx or similar symbols IOBJ and IPTR are empty, making the types equivalent to, for example, 'const char' and 'const char*'.  For Atmel compiler these will become 'const __flash char' and 'const __memx char*'.  All printf() functions and syslog() functions are changed so that the qualifier is used with the format parameter.
