/* This file isn't directly used by the test suite; it uses
|
||||
elf_e_flags.s. However, I figured it would be nice to provide the
|
||||
source code from which the .s file was generated.
|
||||
|
||||
It was compiled as follows:
|
||||
|
||||
mips64-elf-gcc -m4650 -S -O elf_e_flags.c
|
||||
|
||||
We use the -m4650 flag to get the 4650-specific 'mul' instruction
|
||||
in there; the test suite wants to be sure that GAS's -m4650 flag
|
||||
will indeed cause it to generate the 4650 mul instruction, and not
|
||||
expand it as a macro. */
