2012-05-09Add volatiles for x86-64 bits/mathinline.hAndreas Jaeger
[BZ #14053] GCC 4.7 might remove consecutive calls to e.g. lrintf since the assembler instructions are the same and GCC does not know that the result is different depending on the rounding mode. For SSE instructions, the control register is not available so there is no way to inform GCC about this. Therefore the asms are marked as volatile.

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.
