- Subject: using emit_library_call
Hi,
Can emit_library_call be used at any point during RTL generation with any
rtx's as as arguments (to be used as arguments to the library function I
wish to call)? I'm trying to do that right now, but it doesn't always
work. Do I have to take care of anything else first, like make
sure the caller saved registers are saved?
Also, the comment to emit_library_call mentions a function called
'protect_from_queue'; what does it mean that an expression is queued?
I would *really* appreciate any help I can get on these issues!
