51596dc457 Updata difftime. Add a version of difftime for the case where the platform does not support type double 2016-08-25 08:00:50 -06:00
Sebastien Lorquet
a626ba5b70 libc/time: This commit adds the difftime() function. Since the function returns a double, I have isolated it in a CONFIG_LIBC_DIFFTIME option (It also depends on the toolchain-dependent CONFIG_HAVE_DOUBLE so is not available on tiny platforms). 2016-08-24 15:43:57 -06:00

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.

261358f1f5 This change should significantly improve the performance of single precision floating point math library functions. The vast majority of changes have to do with preventing the compiler from needlessly promoting floats to doubles, performing the calculation with doubles, only to demote the result to float. These changes only affect the math lib functions that return float. 2016-07-11 07:02:50 -06:00

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.

5ac6de118e libc/math/lib_asin.c: The function did not convert for some input values. Asin did not convert for values which do not belong to the domain of the function. But aside of that the function also did not convert for sine allowed values. I achieved a conversion of the function by reducing the DBL_EPSION and by checking if the input value is in the domain of the function.

23035ca68d [PATCH] gethostbyname(): correct returned address format when DNS is used. The hostent.h_addr_list should point to raw in_addr or in6_addr as defined in the standard. Original implementation used that 
for numeric addresses but for DNS lookup returned pointer to whole sockaddr_in or sockaddr_in6.

getaddrinfo() should be preferred in a long term perspective. Return of complete addresses from the lookup would be better in such case but it requires significant changes anyway - multiple addresses support and most probably dynamic memory allocation which is bad for many RT applications. So gethostbyname() is sufficient for most applications now.

This can be easily seen e.g. with x = 1E-30, the results are all zero though they should be extremely close to x. The cutoff values (1E-5, 1E-9) are chosen so that the next term in the Taylor series is negligible (for double). Functions could maybe be optimized to use only first term (x) and a smaller cutoff, just bigger than where the cancellation occurs. 2015-04-09 10:35:07 -06:00
