Ok, let's try one more time. Previous attempt: https://sourceware.org/ml/libc-alpha/2015-10/msg00894.html Tested on Linux/x86_64 with 6.0.0 (r222386). Testing with (gcc-4.8 Ubuntu 4.8.4-2ubuntu1~14.04) 4:4.8.2-1ubuntu6 fails for apparently unrelated reasons: build/math/test-double-vlen2-wrappers.o: In function `cos_vlen2': /glibc-git/math/../sysdeps/x86_64/fpu/test-double-vlen2-wrappers.c:24: undefined reference to `_ZGVbN2v_cos' /glibc-git/build-system-gcc/math/test-double-vlen2-wrappers.o: In function `sin_vlen2': /glibc-git/math/../sysdeps/x86_64/fpu/test-double-vlen2-wrappers.c:25: undefined reference to `_ZGVbN2v_sin' ... etc. Thanks, 2015-12-07 Paul Pluzhnikov <ppluzhnikov@google.com> [BZ #19165] * misc/sys/cdefs.h (__umul_size_t_overflow): New. (__umul_size_t_saturated): New. * libio/iofread.c (_IO_fread): Protect against overflow. * libio/iofread_u.c (__fread_unlocked): Likewise. * b/libio/iofwrite.c (_IO_fwrite): Likewise. * libio/iofwrite_u.c (fwrite_unlocked): Likewise. -- Paul Pluzhnikov
