{Global variables (in implementation part of course)
*can* be loaded into registers, they just may not be
accessed from procedures. The lexlevel test in nld.pas,
Tloadnode.pass_1, should take care of this.
If for some reason you think it isn't safe, try isolating
and disabling those specific cases, because small programs
without procedures can be very speed critical. For example,
think of benchmarks and programming contests. Also, new
users often test the quality of the code the compiler
generates and they do that with small programs, we should
show them the full optimizing power. (DM)}

Revision 1.43 2002/07/20 11:57:58 florian
* types.pas renamed to defbase.pas because D6 contains a types
unit so this would conflicts if D6 programms are compiled
+ Willamette/SSE2 instructions to assembler added
