Re: Gnat Asm Insertion Question

["Michael Garrett" <michaelgarrett@csi.com>]

I chaged the code to read:

Asm (Latin_1.LF & Latin_1.HT &
           "movl %%cr0,%%eax; "    & Latin_1.LF & Latin_1.HT &
           "or $0x0001,%%eax; "      & Latin_1.LF & Latin_1.HT &
           "movl %%eax,%%cr0; "    & Latin_1.LF & Latin_1.HT &
           "ljmp $0x10,$1f; "              & Latin_1.LF &
           "1: "                                     & Latin_1.LF &
Latin_1.HT &
           "movl $0x18,%%eax; "     & Latin_1.LF & Latin_1.HT &
           "movl %%eax,%%ds; "     & Latin_1.LF & Latin_1.HT &
           "movl %%eax,%%es; "     & Latin_1.LF & Latin_1.HT &
           "movl %%eax,%%fs; "      & Latin_1.LF & Latin_1.HT &
           "movl %%eax,%%gs; "     & Latin_1.LF & Latin_1.HT &
           "movl %%eax,%%ss; ",
           No_Output_Operands,
           No_Input_Operands);

In a Put statement, this gives me formated asm code with the label in the
first location on the line.
But the compiler is still choking after the label.

I took this code from a web reference which was supposed to have compiled at
one time.....
