* Changes For Bug 352Reid Spencer2004-09-01
| | | | | | | | | Move include/Config and include/Support into include/llvm/Config, include/llvm/ADT and include/llvm/Support. From here on out, all LLVM public header files must be under include/llvm/. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16137 91177308-0d34-0410-b5e6-96231b3b80d8

* The CodeEmitterGenerator used to consider ANY uninitialized field as being anChris Lattner2003-08-05
| | | | | | | | operand (unless it's annul or predict). Now we only consider fields to be operands if they are uninitialized AND used in the "Inst" field. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7589 91177308-0d34-0410-b5e6-96231b3b80d8

* Fixed a bug: outputting name of variable instead of its value.Misha Brukman2003-07-15
| | | | | | | | Also, placed DEBUG() guards around debug information so that the generated file is much smaller and hence should be faster to preprocess/compile. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7180 91177308-0d34-0410-b5e6-96231b3b80d8
* This optimization greatly enhances efficiency of creating new instructions byMisha Brukman2003-07-15
| | | | | | | | masking and shifting operands directly into their place in the instruction, instead of the old-fashioned way of ORing in each bit separately. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7179 91177308-0d34-0410-b5e6-96231b3b80d8
* Stop using the `Offset' variable, as we are cycling through the bits of a fieldMisha Brukman2003-07-07
| | | | | | | | initializer and the loop index variable already carries the offset information that we need. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7123 91177308-0d34-0410-b5e6-96231b3b80d8

* * Stop ignoring cc registers, since we actually use them in branches.Misha Brukman2003-06-05
| | | | | | | * Added comment as to why we are still ignoring predict and annul bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6636 91177308-0d34-0410-b5e6-96231b3b80d8

* Cannot output `static' in generated cpp code: results in error. It's alreadyMisha Brukman2003-05-27
| | | | | | | specified as a static member in class definition. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6370 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | * For debugging purposes: + output the predefined bit pattern of the instruction * Fixed inefficiency: only load an operand from MachineInstr once * Bug fix: did not advance bit index when seeing named bit-fields "annul", "cc" and "predict" * Added a catch-all for non-supported instructions at the end of switch stmt. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6368 91177308-0d34-0410-b5e6-96231b3b80d8
