[llvm-commits] CVS: llvm/lib/CodeGen/ELFWriter.cpp

[Chris Lattner]

Changes in directory llvm/lib/CodeGen:

ELFWriter.cpp updated: 1.21 -> 1.22
---
Log message:

Several related changes:

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.
