2013-01-02Fix values in __mpexp_twomm1Siddhesh Poyarekar
2013-01-02Split mantissa calculation loop and add branch predictionSiddhesh Poyarekar
2013-01-02Add assert for potential access beyond array bounds in m1npSiddhesh Poyarekar
The mpexp code has an access into m1np: for (i=n-1; i>0; i--,n--) { if (m1np[i][p]+m2>0) break; } which could break for p >= 18 or i >= 7. Fortunately this code is never called due to the way the exp function is implemented since values having exponent less than -55 return 1.0. Make sure that if it gets called in future, it is trapped.

2012-12-06linux: posix_fadvise: support __NR_fadvise64_64Mike Frysinger
Some arches do not have a __NR_fadvise64 but do have __NR_fadvise64_64. If the former is unavailable, fallback to the latter. Reviewed-by: Carlos O'Donell <carlos@systemhalted.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-12-03byteswap.h: fix gcc ver test for __builtin_bswap{32,64}Mike Frysinger
The __builtin_bswap* functions were introduced in gcc-4.3, not gcc-4.2. Fix the __GNUC_PREREQ tests to reflect this. Otherwise trying to compile code with gcc-4.2 falls down: In file included from /usr/include/endian.h:60, from /usr/include/ctype.h:40, /usr/include/bits/byteswap.h: In function 'unsigned int __bswap_32(unsigned int)': /usr/include/bits/byteswap.h:46: error: '__builtin_bswap32' was not declared in this scope /usr/include/bits/byteswap.h: In function 'long long unsigned int __bswap_64(long long unsigned int)': /usr/include/bits/byteswap.h:110: error: '__builtin_bswap64' was not declared in this scope Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-11-20Hurd: fixes for ptsname and ptsname_rPino Toscano
ptsname_r on failure returns the value that is also set as errno; furthermore, add more checks to it: - set errno and return it on __term_get_peername failure - set errno to ERANGE other than returning it - change the type of PEERNAME to string_t, and check its length with __strnlen In ptsname: - change the type of PEERNAME to string_t - do not set errno manually, since ptsname_r has set it already
