Daniel Dunbar d83889bd87 MC: Eliminate MCSectionData::{,Address,File}Size, which can now be computed by
utility functions.

Daniel Dunbar c7c53ea715 MC: Switch to using explicit MCAlignFragments with OnlyAlignAddress bit instead
of manually doing padding/editing layout in LayoutSection().
    - This probably seems like six-of-one and half-dozen of another, but there
      is a method to my madness.

Evan Cheng 9de7cfe3f4 Bring back VLD1q and VST1q and use them for reloading / spilling Q registers. This allows folding loads and stores into VMOVQ.

Daniel Dunbar a6780da661 MC: Add MCAlignFragment::OnlyAlignAddress bit. This is a bit of magic that says the align fragment shouldn't contribute to the logical section size, it is will be used for cleaning up the code to handle section alignment.

2010-05-13 01:10:26 +00:00
Daniel Dunbar 4dac59dcb7 MC: Add MCSectionData::AddressSize, which is the size of the address space consumed by the section. This can differ from both the section logical size, and the section size on disk (although the current code handles this without making an explicit distinction).

Ted Kremenek 12e0f2937e Specially handle CaseStmts in CursorVisitor because they can be nested and walking them
can blow out the stack.

Jakob Stoklund Olesen 0ba2e2a568 Take allocation hints from copy instructions to/from physregs.
This causes way more identity copies to be generated, ripe for coalescing.

Chris Lattner 8cb4728a15 fix rdar://7965971 and a fixme: use ParseIdentifier in
ParseDirectiveDarwinZerofill instead of hard coding the
check for identifier. This allows quoted symbol names to
be used.

Devang Patel c5ffabc94f If given location is invalid then use current location.
This fixes recent regressions reported by gdb testsuite. 
Tighter verification of debug info generated by FE found these regressions.

Refactor code to extract line number and column number from SourceLocation.

Chris Lattner bf5c83745a "this patch properly addresses escaping < and > which might appear
(e.g. for C++ operators) in the xml dump.

I also re-enabled the unit test for ast-print-xml (or so I think)
at least, make test didn't fail..."

Chris Lattner a6df4650fd moffset forms of moves are x86-32 only, make the parser
lower them to the correct x86-64 instructions since we 
don't have a clean way to handle this in td files yet.

Evan Cheng 7c1f56f29a Fix some potential issues in the pseudo instruction expansion phase: copy implicit operands and memoperands. Also, expand instructions even if their defs are "dead" since they may have implicit kill operands.

Daniel Dunbar 597eb48168 MC: Switch MCFillFragment to storing total fill size instead of a count. This allows using ValueSize==0 to represent a virtual fill.

Chris Lattner 27de3d6459 improve the 'current status' section to say what *is* there in
addition to what is not.

Add a big "why libc++" section to address a pretty major FAQ.

Daniel Dunbar 6399208c14 Revert "Move macro definitions for IBOutlet and IBAction into the source
code. ...", this was a lit bug which should be fixed in r103652.

Nick Lewycky c63aa1e8ab Clear CachedFunctionInfo upon Pass::releaseMemory. Because ValueMap will abort
on RAUW of functions, this is a correctness issue instead of a mere memory
usage problem.


No testcase until the new MergeFunctions can land.

Daniel Dunbar 12a78f502a lit: Fix a sh lexing bug which caused annotate-token.m to fail when run with the
internal shell parser; we weren't lexing the quotes in a command like::

  clang -DFOO='hello'

Daniel Dunbar 959ae59997 ADT: Add ilist_node::get{Prev,Next}Node, which return the adjacent node or null.
- This provides a convenient alternative to using something llvm::prior or
   manual iterator access, for example::

    if (T *Prev = foo->getPrevNode())
      ...

   instead of::

     iterator it(foo);
     if (it != begin()) {
       --it;
       ... 
     }

 - Chris, please review.
