From ee876e59156337667c4945c3346c0c7876f3a98c Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Mon, 9 Mar 2015 19:25:28 +0100 Subject: [PATCH] re PR sanitizer/63958 (bootstrap failure in the sanitizer libs on sparc-linux-gnu) PR sanitizer/63958 Reapply: 2014-10-14 David S. Miller * sanitizer_common/sanitizer_platform_limits_linux.cc (time_t): Define at __kernel_time_t, as needed for sparc. (struct __old_kernel_stat): Don't check if __sparc__ is defined. * libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.h (__sanitizer): Define struct___old_kernel_stat_sz, struct_kernel_stat_sz, and struct_kernel_stat64_sz for sparc. (__sanitizer_ipc_perm): Adjust for sparc targets. (__sanitizer_shmid_ds): Likewsie. (__sanitizer_sigaction): Likewise. (IOC_SIZE): Likewsie.
