Chris Lattner 71957a90b3 Test that we get rep movs when calling memcpy 
llvm-svn: 11352
 2004-02-12 17:53:43 +00:00
Chris Lattner 8dc99feeaf Add support for the rep movs[bwd] instructions, and emit them when code 
generating the llvm.memcpy intrinsic.

Alkis Evlogimenos 537805f315 Change interface so that we can add to the end of a basic block 
without getting an assertion from ilist that we are dereferencing
ilist<T>::end().

Brian Gaeke 974a21e6fb Express one of MachineOperand's many constructors in terms of another, by means of default arguments.

Brian Gaeke c07b64f3cb Remove this MachineOpCodeFlags assertion - its test can never be false. 
llvm-svn: 11342
 2004-02-12 04:01:07 +00:00
Brian Gaeke 84262c112c Remove these MachineOpCodeFlags and their accessor - they are never set.

Alkis Evlogimenos 80da865f77 Change MachineBasicBlock's vector of MachineInstr pointers into an 
ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.

instead of dropping them entirely.

Brian Gaeke 512bd8de00 Fix bug in initial check - when recompiling everything with llvm-native-gcc, 
you have to erase the program and re-run the linker, too, before running the
checker.

Brian Gaeke 228a29b711 add description of -check-exit-code 
llvm-svn: 11326
 2004-02-11 18:40:04 +00:00
Brian Gaeke 35145beb61 Add check-exit-code option, defaulting to true. 
Add ProgramExitedNonzero argument to executeProgram(), and make it
tell its caller whether the program exited nonzero.

Move executeProgramWithCBE() out of line, to ExecutionDriver.cpp, and remove
its extra arguments which are always defaulted.  Make it turn off
check-exit-code if the program exits nonzero while generating a reference
output.

Make diffProgram() assume that any nonzero exit code is a failure, if
check-exit-code is turned on.

Chris Lattner f10f6b10f9 Actually load profiling information now! Block layout can use real, live, 
actual profile info, and works!  :)

Alkis Evlogimenos fcb99fe370 Fix previous broken commit. A MachineOperand may have opType == 
MO_VirtualRegister but if the register number is one of a physical
register is it considered as a physical register.

 2004-02-11 05:00:27 +00:00
Chris Lattner 5add05129e Add an _embarassingly simple_ implementation of basic block layout. This is 
more of a testcase for profiling information than anything that should reasonably
be used, but it's a starting point.  When I have more time I will whip this into
better shape.

llvm-svn: 11311
 2004-02-11 04:53:20 +00:00
Alkis Evlogimenos adcc14d96a Remove assert as it is meaningless. MachineOperands can be tagged as 
MO_VirtualRegister but actually be representing a physical register.

llvm-svn: 11310

Chris Lattner 18d1f19fba Implement SimplifyCFG/PhiEliminate.ll 
Having a proper 'select' instruction would allow the elimination of a lot
of the special case cruft in this patch, but we don't have one yet.
