>Description:
Output of executing the following command:-
gcc ldmxcsr.s
ldmxcsr.s: Assembler messages:
ldmxcsr.s:1: Error: no such 386 instruction: 'ldmxcsr'
>How-To-Repeat:
Data is a one line file called <anything.s> with the
following line in it:-
ldmxcsr -4(%ebp)
>Fix:
If you pass the same one line file through the AS program
directly, it assembles fine.
I had to assemble the program that used this instruction
with the -S option to stop after the Assembler creation
step.
Then I had to pass the output throught the AS Assembler to
create the output module.
I then had to <kluge> the Makefile to bypass assembling this
program.
