eqgraph passes from 1.5s to .16s on the same.

Duraid Madina 50b339b7fa ia64 asmprinter fixes:
- turn off assembler's autoalignment
  - set FunctionAddrPrefix/Suffix so that .data8 entries pointing to
    functions have their value wrapped in @fptr(), so that a function
    descriptor will be materialized for that function.

llvm-svn: 21025
2005-04-02 12:30:47 +00:00
Duraid Madina 73a316d712 add support for prefix/suffix strings to go around GlobalValue(s)
(which may or be function pointers) in the asmprinter. For the moment,
this changes nothing, except the IA64 backend which can use this to write:

  data8.ua  @fptr(blah__blah__mangled_function_name)

  (by setting FunctionAddrPrefix/Suffix to "@fptr(" / ")")

Chris Lattner 13fe99c807 Several changes mixed up here. First when legalizing a DAG with pcmarker,
dont' regen the whole dag if unneccesary.  Second, fix and ugly bug with
the _PARTS nodes that caused legalize to produce multiples of them.
Finally, implement initial support for FABS and FNEG.  Currently FNEG is
the only one to be trusted though.

Duraid Madina 21ce5f7a66 Assorted fixes:
* Stop being pessimistic about output register allocation
  * Start to handle function descriptors: compute target GPs and so on
  when doing indirect calls etc. Not there yet, though. For the moment,
  we try to use _indirect_ branches wherever possible, to stress test
  function descriptors.
  * FP divide-by-zero should work now
  * add varargs (it doesn't work, though)

At this point, all of SingleSource passes (modulo C++ tests that are due
to issues with the CFE, see note in the README.) Much of MultiSource also
passes although there's still a ton of bugs around. Something for me to
work on tomorrow, then. :)
