| | | | | | | | | | [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.

* Fix ilogb exception and errno (bug 6794)Adhemerval Zanella2012-04-171-3/+8
| | | | | | | | | | | | | | | | | | | | [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.
