2012-04-17Fix ilogb exception and errno (bug 6794)Adhemerval Zanella
[BZ #6794] Following Joseph comments about bug 6794, here is a proposed fix. It turned out to be a large fix mainly because I had to move some file along to follow libm files/names conventions. Basically I have added wrappers (w_ilogb.c, w_ilogbf.c, w_ilogbl.c) that now calls the symbol '__ieee754_ilogb'. The wrappers checks for '__ieee754_ilogb' output and set the errno and raise exceptions as expected. The '__ieee754_ilogb' is implemented in sysdeps. I have moved the 's_ilogb[f|l]' files to e_ilogb[f|l] and renamed the '__ilogb[f|l]' to '__ieee754_ilogb[f|l]'. I also found out a bug in i386 and x86-64 assembly coded ilogb implementation where it raises a FE_DIVBYZERO when argument is '0.0'. I corrected this issue as well. Finally I added the errno and FE_INVALID tests for 0.0, NaN and +-InF argument. Tested on i386, x86-64, ppc32 and ppc64.

2012-04-07memset: fix define usage for shared libsMike Frysinger
The proper define to check "am I in a shared lib" is "SHARED", not "PIC". The two new memset_chk functions incorrectly depend on "PIC". Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-04-06Add byteswap-16.h for __bswap_16H.J. Lu
2012-04-05Fix size parameter comparisions.Michael Matz
[BZ #13592] There are several signed compares of the size argument, whereas it really is unsigned. Depending on situations e.g. a "memset(ptr, 0, -1)" segfault (but for the wrong reasons, because jumping into nirvana) or succeeds even. In normal use this is harmless, as a size with signbit set indicates more than half the address space which on x86_64 is impossible to allocate, but as the size is used to index some jump tables this potentially could have other unwanted side effects.
2012-04-03Add __bswap_64 definition for non GCC compilers.Andreas Jaeger
[BZ#13926] Currently __bswap_64 is not defined at all for non-GCC compilers. Define it but guard it with __GLIBC_HAVE_LONG_LONG. endian.h uses __bswap_64, make the functions only available if __GLIBC_HAVE_LONG_LONG is defined.
