and extern_weak_odr. These are the same as the non-odr versions,
except that they indicate that the global will only be overridden
by an *equivalent* global. In C, a function with weak linkage can
be overridden by a function which behaves completely differently.
This means that IP passes have to skip weak functions, since any
deductions made from the function definition might be wrong, since
the definition could be replaced by something completely different
at link time. This is not allowed in C++, thanks to the ODR
(One-Definition-Rule): if a function is replaced by another at
link-time, then the new function must be the same as the original
function. If a language knows that a function or other global can
only be overridden by an equivalent global, it can give it the
weak_odr linkage type, and the optimizers will understand that it
is alright to make deductions based on the function body. The
code generators on the other hand map weak and weak_odr linkage
to the same thing.

them are generic changes.
- Use the "fast" flag that's already being passed into the asm printers instead
of shoving it into the DwarfWriter.
- Instead of calling "MI->getParent()->getParent()" for every MI, set the
machine function when calling "runOnMachineFunction" in the asm printers.

a DBG_LABEL or not. We want to fall back to the original way of emitting debug
info when we're in -O0/-fast mode.
- Add plumbing in to pass the "Fast" flag to places that need it.
- XFAIL DebugInfo/deaddebuglabel.ll. This is finding 11 labels instead of 8. I
need to investigate still.
llvm-svn: 65367
* Linters now return their information instead of printing it, to
enable easier unittesting
* Added support for finding tabs in files, added to C++ linter
llvm-svn: 65202
function. Emitting another label after the prologue messes up the debugging. We
are doing that because the first DebugLoc object it sees is different from the
previous, which was nothing. Check for this situation, and don't emit one if
it's the first.

Cleanup some warning.
Remark: when struct/class are declared differently than they are defined, this make problem for VC++ since it seems to mangle class differently that struct. These error are very hard to understand and find. So please, try to keep your definition/declaration in sync.
Only tested with VS2008. hope it does not break anything. feel free to revert.

target directories themselves. This also means that VMCore no longer
needs to know about every target's list of intrinsics. Future work
will include converting the PowerPC target to this interface as an
example implementation.

crashes or wrong code with codegen of large integers:
eliminate the legacy getIntegerVTBitMask and
getIntegerVTSignBit methods, which returned their
value as a uint64_t, so couldn't handle huge types.
llvm-svn: 63494
- Modify TableGen to add the DebugLoc when calling getTargetNode.
(The light-weight wrappers are only temporary. The non-DebugLoc version will be
removed once the whole debug info stuff is finished with.)
llvm-svn: 63273
to handle LLVMMatchType intrinsic parameters, and by adding new subclasses
of LLVMMatchType to match vector types with integral elements that are
either twice as wide or half as wide as the elements of the matched type.
llvm-svn: 61834
- After GlobalAssign, emit addrspace before global/constant, to follow
the new syntax.
- Eliminate "type void", which is now invalid.
- Fix invalid liblists like [, "foo"].
- Tweak whitespace in a few places.
llvm-svn: 61706
- Add several new keywords
- Clean up some obsolete keywords
- Improve the patterns for constants.
- Add syntax-highlighting for dejagnu test command comments
llvm-svn: 61646
smarter about C-ish syntax, and supports the cinoptions
variable. Set cinoptions to suppress the extra indentation
for switch case labels.
llvm-svn: 61617
* Fixed cursors in terminal by setting nocompatible (sorry, vi users)
* Enable syntax highlighting so that this file can stand on its own
* Highlight trailing whitespace
* Fixed commands to delete trailing whitespaces and convert tabs to spaces
llvm.vim and tablegen.vim
* Removed trailing whitespace, as it's now very visible
llvm-svn: 61582
* Added the first LLVM unittest -- DenseMap.
* Updated mkpatch utility to include llvm/unittests dir
* Added top-level target "unittests" to run all unittests
llvm-svn: 61541
* Removed gtest_main.cc: we have our own main() elsewhere
* Simplified the Makefile as we don't need SOURCES
* Moved the internal header to gtest/internal/
* Simplified the Makefile to remove -I param to CPP.Flags
* Updated README.LLVM with all the steps I took to massage GTest to
work in LLVM so far
llvm-svn: 61540
Makefile with it, without resorting to the use of VPATH.
Also added Makefiles at every level of the directory tree to properly recurse
to Google Test and build it as a library (original Makefiles by Talin).
