Rao <naveen.n.rao@linux.vnet.ibm.com> # Date: Wed Oct 31 22:48:13 2018 +0530 # # selftests/powerpc: Fix compilation issue due to asm label # # We are using 'dscr_insn' as a label in inline asm to identify if a # SIGILL was generated by the mtspr instruction at that point. However, # with inline assembly, the compiler is still free to duplicate the asm # statement for optimization purposes, which results in the label being # defined twice with the error: # /tmp/ccerQCql.s:874: Error: symbol `dscr_insn' is already defined # # With different compiler versions, we may also see: # /tmp/ccJzLDlN.o:(.toc+0x0): undefined reference to `dscr_insn' # # Remove the use of the label in the inline assembly. Instead, just look # for the offending instruction in the signal handler. # # Fixes: d2bf793237b3 ("selftests/powerpc: Add test to verify rfi flush across a system call") # Reported-by: Breno Leitao <leitao@debian.org> # Signed-off-by: Naveen N.
