-Subject: [PATCH] mips: Do not include hi and lo in __SYSCALL_CLOBBERS for R6
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-From [1]
-"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."
