Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn't
...
working. To support this, add an is_displayed() function to raw_ostream,
and generalize Process::StandardOutIsDisplayed and friends in order to
support it.
Also, call RemoveFileOnSignal before creating a file instead of after, so
that the file isn't left behind if the program is interrupted between when
the file is created and RemoveFileOnSignal is called.
While here, add a -S to llvm-extract and port it to IRReader so that it
supports assembly input.

Prune #includes from llvm/Linker.h and llvm/System/Path.h,
...
forcing them down into various .cpp files.
This change also:
1. Renames TimeValue::toString() and Path::toString() to ::str()
for similarity with the STL.
2. Removes all stream insertion support for sys::Path, forcing
clients to call .str().
3. Removes a use of Config/alloca.h from bugpoint, using smallvector
instead.
4. Weans llvm-db off <iostream>
sys::Path really needs to be gutted, but I don't have the desire to
do it at this point.

Make the JIT code emitter properly retry and ask for more memory when it runs
...
out of memory, and also make the default memory manager allocate more memory
when it runs out.
Also, switch function stubs and global data over to using the BumpPtrAllocator.
This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB
of memory, and instead allocates in 512K slabs. I suspect this size could go
lower, especially on embedded platforms, now that more slabs can be allocated.

Eliminate the static constructors and locks from DynamicLibrary.cpp.
...
This fixes PR4512 and eliminating static ctors is always good. Losing
thread safety is unfortunate, but the code is just incredibly poorly
designed.
If someone is interested, the "right" solution is to split
DynamicLibrary.cpp into two separate pieces: a stateless piece in
libsystem, and a simple support file in libsupport that has the
"state" (e.g. AddSymbol) in managed static objects.
Doing this would both fix memory leaks we already have, as well as make
the code thread safe again. it would also make sense to move all the
unix specific code in System/DynamicLibrary.cpp into
System/Unix/DynamicLibrary.inc.

glibc has two versions of strerror_r, a standards compliant one and a GNU
...
specific one. The GNU one is chosen when _GNU_SOURCE is defined. g++ always
defines _GNU_SOURCE on linux platforms because glibc's headers won't compile
in C++ mode without it. The GNU strerror_r doesn't always modify the buffer
which causes empty error messages on linux.
This patch changes MakeErrMsg to use the return value of strerror_r to get
the string instead of assuming the buffer will be modified, on GLIBC.

Fix g++-4.4.0 warning, it was causing llvm-nm to fail on wrapped BC files:
...
Path.cpp:59: warning: case label value exceeds maximum value for type
magic[0] is a (signed) char, but some case values are unsigned (e.g. 0xde).
When magic[0] was 0xde, the switch has taken the default branch instead of case
0xde branch.
Apparently this was the behaviour with older versions of gcc too, but not with g++.
Now g++-4.4 behaves as gcc, and ignores unsigned case values out of range signed
range.

Add llvm::sys::getHostTriple and remove
...
llvm::sys::getOS{Name,Version}.
Right now the implementation just derives from LLVM_HOSTTRIPLE (which
is wrong, but it doesn't look like we have a define for the target
triple). Ideally this routine would actually be able to compute the
triple for targets we care about.

Fix the Win32 VS2008 build:
...
- Make type declarations match the struct/class keyword of the definition.
- Move AddSignalHandler into the namespace where it belongs.
- Correctly call functions from template base.
- Some other small changes.
With this patch, LLVM and Clang should build properly and with far less noise under VS2008.

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.
