[llvm-commits] [PATCH] MCFragments Clean Up

[David Meyer]

Hi Dan,

This patch against rev 116493 does the following:

* Adds four virtual methods to MCFragment:
    ComputeSize() - Compute the size of this fragment
    WriteData() - Write the data of this fragment
    AssertLegalInVirtualSection() - Assert that this fragment is legal
in a virtual section
    dump_kind_data() - Dump the kind-specific data for this fragment

* Moves the implementation of these actions from MCAssembler.cpp to a
new file "MCFragment.cpp"

* As a benefit, most of the switches on MCFragment::Kind and many of
the MCFragment casts go away.

* Introduces the PendingLayout flag to make it possible to reuse the MCAsmLayout
getter functions (i.e. getFragmentAddress() and getFragmentOffset())
while inside of
ComputeSize().

Thanks. Please let me know what you think.
