Fix PR17493, attempted output of *GAS `reg' section* symbol
The write.c change is to make gas report an error if reg_section symbols should leak in future. The tc-i386.c change is the real fix. Note that the error isn't the most helpful, "redefined symbol cannot be used on reloc", but I'm not inclined to improve what is really an internal gas error. reg_section symbols shouldn't leak.. gas/ PR 17493 * write.c (adjust_reloc_syms): Don't allow symbols in reg_section to be reduced to reg_section section symbol. * gas/config/tc-i386.c (i386_finalize_immediate): Reject all reg_section immediates. gas/testsuite/ * gas/i386/inval-equ-2.l: Adjust.
