I have the following snippet of code to put the processot into protected
mode:

Asm ("movl %%cr0,%%eax; " &
           "or $0x0001,%%eax; " &
           "movl %%eax,%%cr0; " &
           "ljmp $0x10,$1f; " &
           "1: " &
           "movl $0x18,%%eax; " &
           "movl %%eax,%%ds; " &
           "movl %%eax,%%es; " &
           "movl %%eax,%%fs; " &
           "movl %%eax,%%gs; " &
           "movl %%eax,%%ss; ",
           No_Output_Operands,
           No_Input_Operands);

When I try to compile this code, I get the following error:

C:\TEMP\cca00281.s: Assembler messages:
C:\TEMP\cca00281.s:89: Error: operands given don't match any known 386
instructi
on
gnatmake: "hardware\adaos-hardware-processor.adb" compilation error
make: *** [make_ada_main] Error 4

For some reason, the label for the ljmp instruction is not declared
properly.

How do I properly write this code so that the compiler creates a label?

Thank you in advance!!
