* libm: fix invalid result of function remquo/remquofJack Ren2012-04-102-6/+8
| | | | | | | | | | | | | | | | | | | Currently we will get the wrong result as follows: remquof(0x7bb33336, 0x63000000) = -671088640, 0x00000000 remquo(0xbff0000000000003, 0x3ff0000000000003) = 1, 0x8000000000000000 remquo(0x9120000000000001, 0x0000000000000005) = -1288490188, 0x0000000000000004 while the correct one should be: remquof(0x7bb33336, 0x63000000) = 1476395008, 0x00000000 remquo(0xbff0000000000003, 0x3ff0000000000003) = -1, 0x8000000000000000 remquo(0x9120000000000001, 0x0000000000000005) = -1288490189, 0x0000000000000001 Fixed in this patch.

* remove obsolete SuperH supportDavid 'Digit' Turner2012-01-311-11/+1
| | | | | | | | | | | | | | | | | | | We don't have a toolchain anymore, we don't have working original kernel headers, and nobody is maintaining this so there is really no point in keeping this here. Details of the patch: - removed code paths from Android.mk files related to the SuperH architecture ("sh") - removed libc/arch-sh, linker/arch-sh, libc/kernel/arch-sh - simplified libc/SYSCALLS.TXT - simplified the scripts in libc/tools/ and libc/kernel/tools Change-Id: I26b0e1422bdc347489e4573e2fbec0e402f75560 Signed-off-by: David 'Digit' Turner <digit@android.com>

* | | Disable sincos optimization for sincos calls.Jing Yu2011-08-171-0/+8
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sincos() functions would be turned into infinite calls to itself if sincos optimization is applied to itself. See gcc bugzilla http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46926 arm-linux-androideabi-4.4.3 toolchain does not have this problem because sincos optimization is entirely disabled. Starting from arm-linux-androideabi-4.6 toolchain, we enable sincos optimization in gcc. This patch simply enforce -O0 on this function to minimize the change.

| * / Bionic: Aliasing problems with frexpfRodrigo Obregon2010-11-051-1/+1
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a known bug in bionic libm due to aliasing issues in gcc 4.2 and 4.4; more specifically in frexpf. The function frexpf is used to extract the mantissa and exponent from a double precision number.

So I switched to using the unmasked hx and added a cast as a reward to the compiler for being right. I checked the original routines that e_j0f.c was ported from (in e_j0.c) and the double's don't use 0x80000000 so this issue didn't exist there. Let that be a warning to those that just slap on casts to shut up the compiler, sometimes it's sniffed out a bug for you. :-) Similar fixes in the other functions.
