Dragan Mladjenovic 020b2a97bb mips: Do not include hi and lo in __SYSCALL_CLOBBERS for R6 ... GCC 10 (PR 91233) won't silently allow registers that are not architecturally available to be present in the clobber list anymore, resulting in build failure for mips*r6 targets in form of: ... .../sysdep.h:146:2: error: the register ‘lo’ cannot be clobbered in ‘asm’ for the current target 146 | __asm__ volatile ( \ | ^~~~~~~ This is because base R6 ISA doesn't define hi and lo registers w/o DSP extension. This patch provides the alternative definitions of __SYSCALL_CLOBBERS for r6 targets that won't include those registers. * sysdeps/unix/sysv/linux/mips/mips32/sysdep.h (__SYSCALL_CLOBBERS): Exclude hi and lo from the clobber list for __mips_isa_rev >= 6. * sysdeps/unix/sysv/linux/mips/mips64/n32/sysdep.h (__SYSCALL_CLOBBERS): Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/sysdep.h (__SYSCALL_CLOBBERS): Likewise.		2019-12-16 19:35:22 +01:00
