Old (<= 2.8.1) versions of gcc generate broken fsubp, fsubrp, fdivp and fdivrp instructions. Assembler translates them to correct ones with a warning: [hjl@gnu-cfl-1 gas]$ cat x.s fsubp %st(3),%st [hjl@gnu-cfl-1 gas]$ gcc -c x.s x.s: Assembler messages: x.s:1: Warning: translating to `fsubp %st,%st(3)' [hjl@gnu-cfl-1 gas]$ This patch removes support for old (<= 2.8.1) versions of gcc: [hjl@gnu-cfl-1 gas]$ ./as-new -o x.o x.s x.s: Assembler messages: x.s:1: Error: operand type mismatch for `fsubp' [hjl@gnu-cfl-1 gas]$ gas/ * NEWS: Mention -mold-gcc removal. * config/tc-i386.c (i386_error): Remove old_gcc_only.
