[llvm-commits] CVS: llvm/include/llvm/CodeGen/MachineCodeEmitter.h

[Andrew Lenharth]

Changes in directory llvm/include/llvm/CodeGen:

MachineCodeEmitter.h updated: 1.26 -> 1.27
---
Log message:

Like constants, globals on some platforms are GOT relative.  This means they have to be allocated
near the GOT, which new doesn't do.  So break out the allocate into a new function.

Also move GOT index handling into JITResolver.  This lets it update the mapping when a Lazy
function is JITed.  It doesn't managed the table, just the mapping.  Note that this is
still non-ideal, as any function that takes a function address should also take a GOT
index, but that is a lot of changes.  The relocation resolve process updates any GOT entry
it sees is out of date.
