Message-ID: <9r0vhg$evr$1@suaar1aa.prod.compuserve.com> (raw)
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!!
