This ensures correct execution on targets that have separate dcache and icache. - Added PPC / Mac OS X specific code to do icache flushing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29276 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | simplifies the MachineCodeEmitter interface just a little bit and makes BasicBlocks work like constant pools and jump tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28082 91177308-0d34-0410-b5e6-96231b3b80d8

* Several related changes:Chris Lattner2006-05-021-2/+0
| | | | | | | | | | | | | | 1. Change several methods in the MachineCodeEmitter class to be pure virtual. 2. Suck emitConstantPool/initJumpTableInfo into startFunction, removing them from the MachineCodeEmitter interface, and reducing the amount of target- specific code. 3. Change the JITEmitter so that it allocates constantpools and jump tables *right* next to the functions that they belong to, instead of in a separate pool of memory. This makes all memory for a function be contiguous, and means the JITEmitter only tracks one block of memory now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28065 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a purely hypothetical problem (for now): emitWord emits in the hostChris Lattner2006-05-021-5/+1
| | | | | | | | | byte format. This doesn't work when using the code emitter in a cross target environment. Since the code emitter is only really used by the JIT, this isn't a current problem, but if we ever start emitting .o files, it would be. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28060 91177308-0d34-0410-b5e6-96231b3b80d8
* Refactor the machine code emitter interface to pull the pointers for the currentChris Lattner2006-05-021-7/+11
| | | | | | | | | | | code emission location into the base class, instead of being in the derived classes. This change means that low-level methods like emitByte/emitWord now are no longer virtual (yaay for speed), and we now have a framework to support growable code segments. This implements feature request #1 of PR469. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28059 91177308-0d34-0410-b5e6-96231b3b80d8
