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. This is a fix for the problem but the function should always terminate after a given number of iterations. From Stefan Kolb. 2015-09-01 08:45:14 -06:00

81a257eeb0 Optional canned symtab inclusion to the build. When option CONFIG_LIBC_SYMTAB is selected and symbol table file libc/symtab/canned_symtab.inc is prepared then application can use system provided complete symbol table. The option has substantial effect on system image size. Mainly code/text. If loading of applications at runtime is not planned do not select this. From Pavel Pisa. 2015-08-23 08:38:58 -06:00

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.

5ace3311d9 Repartitioning of DNS client logic in preparation for IPv6 support 
- Rename include/nuttx/net/dnsclient.h to dns.h
- Move internal DNS prototypes from dns.h to libc/netdb/lib_dns.h
- Global standard DNS definitions from libc/netdb/dns_soccket.c to dns.h
- Eliminate dns_gethostip().  This is now an internal part of gethostbyname()
- Eliminate interface dns_whois().  Not needed in this new context.

228b0e1d55 ix an error in time initialization when there is not RTC and the time is initialized from a fixed configured value.

1025c3fb21 Fixes to asinh(), atanh(), and sinh(): The 'basic' expansions all exhibited bad cancellation errors near zero (<= 1E-10). 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

gettimeofday has been decremented in POSIX 2008.  settimeofday() was never part of POSIX, but I decided to add it to libc as well just for symmetry.
