| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lgamma(x) = -log(x) - log(1+x) + x*(1-g) + x**2*P(x) with g = 0.57... being the Euler constant and P(x) a polynomial. Substitution of small into the RHS shows that the last 3 terms are negligible in comparison to the leading term. The choice of 3 may be conservative. The value large=2**(p+3) is detemined from Stirling's approximation lgamma(x) = x*(log(x)-1) - log(x)/2 + log(2*pi)/2 + P(1/x)/x Again, substitution of large into the RHS reveals the last 3 terms are negligible in comparison to the leading term. Move the x=+-0 special case into the |x|<small block. In the ld80 and ld128 implementaion, use fdlibm compatible comparisons involving ix, lx, and llx. This replaces several floating point comparisons (some involving fabsl()) and also fixes the special cases x=1 and x=2. While here . Remove unnecessary parentheses. .

* Back out timegm error check from r272562.ache2014-10-071-2/+0
| | | | | | | POSIX treats negative time_t as undefined (i.e. may be valid too, depends on system's policy we don't have) and we don't set EOVERFLOW in mktime/timegm as POSIX requires to surely distinguish -1 return as valid negative time from -1 as error return.

Modifications to existing code are small and trivial, the netmap-specific code is all in a new file. Please be aware that in netmap mode the physical interface is disconnected from the host stack, so libpcap will steal the traffic not just make a copy.

| | | | | | | | | | | | | | | | | | modifications to libproc to support fetching the CTF info for a given file. With this change, dtrace(1) is able to resolve type info for function and USDT probe arguments, and function return values. In particular, the args[n] syntax should now work for referencing arguments of userland probes, provided that the requisite CTF info is available. The uctf tests pass if the test programs are compiled with CTF info. The current infrastructure around the DTrace test suite doesn't support this yet.

| | | | | | | | | | | | | | | | | | | | Add support for the missing POSIX-2001 %U and %W features: the existing FreeBSD strptime code recognizes both directives and validates that the week number lies in the permitted range, but then simply discards the value. Initial support for the feature was written by Paul Green. David Carlier added the initial handling of tm_wday/tm_yday. Major credit goes to Andrey Chernov for detecting much of the brokenness, and rewriting/cleaning most of the code, making it much more robust.
