Jeffrey Yasskin 4567db45b8 Change the JIT to compile eagerly by default as agreed in 
http://llvm.org/PR5184, and beef up the comments to describe what both options
do and the risks of lazy compilation in the presence of threads.

Chris Lattner 3ed871fe62 add enough support for indirect branch for the feature test to pass 
(assembler,asmprinter, bc reader+writer) and document it.  Codegen
currently aborts on it.

llvm-svn: 84892
 2009-10-22 20:23:43 +00:00
Jeffrey Yasskin 6b80e6e2b7 Add a ValueMap<ValueOrSubclass*, T> type. ValueMap<Value*, T> is safe to use 
even when keys get RAUWed and deleted during its lifetime. By default the keys
act like WeakVHs, but users can pass a third template parameter to configure
how updates work and whether to do anything beyond updating the map on each
action.

It's also possible to automatically acquire a lock around ValueMap updates
triggered by RAUWs and deletes, to support the ExecutionEngine.

Duncan Sands 100d0e3cc1 The gcc plugin is now called dragonegg.so and no longer llvm.so. 
Pointed out by Gabor.

llvm-svn: 84177
 2009-10-15 08:17:44 +00:00
Duncan Sands 8e6ccb65df I don't see any point in having both eh.selector.i32 and eh.selector.i64, 
so get rid of eh.selector.i64 and rename eh.selector.i32 to eh.selector.
Likewise for eh.typeid.for.  This aligns us with gcc, which always uses a
32 bit value for the selector on all platforms.  My understanding is that
the register allocator used to assert if the selector intrinsic size didn't
match the pointer size, and this was the reason for introducing the two
variants.  However my testing shows that this is no longer the case (I
fixed some bugs in selector lowering yesterday, and some more today in the
fastisel path; these might have caused the original problems).

Nick Lewycky 93e06a57c9 Remove the "metadata*" type and simplify the code it complicated. This was only

Nick Lewycky 84a1eeb7ed Move the integer type out of 'derived' and into 'primitive'. This permits us 
to explain that derived types are all composed of other types, which primitive
types aren't. Without moving integer out of derived, this wouldn't be true.

Perform a few trivial cleanups; 'i1' went from a link to #t_primitive to
#t_integer (a holdover from when it was a bool type I suppose).

Nick Lewycky 14b1aacf10 Update the tutorial to match changes to examples/Kaleidoscope.

Dan Gohman e592923603 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.

Jim Grosbach 693e36a3e8 SjLj based exception handling unwinding support. This patch is nasty, brutish 
and short. Well, it's kinda short. Definitely nasty and brutish.

The front-end generates the register/unregister calls into the SjLj runtime,
call-site indices and landing pad dispatch. The back end fills in the LSDA
with the call-site information provided by the front end. Catch blocks are
not yet implemented.

Built on Darwin and verified no llvm-core "make check" regressions.

 - Remove getClosestStaticTargetForModule, the moral equivalent is now:
     lookupTarget(Mod->getTargetTriple, true, false, ...);

 - This no longer does the fuzzy matching with target data (based on endianness
   and pointer width) that getClosestStaticTargetForModule was doing, but this
   was deemed unnecessary.

Bill Wendling a3c6f6bffa Add plumbing for the `linker_private' linkage type. This type is meant for 
"private" symbols which the assember shouldn't strip, but which the linker may
remove after evaluation. This is mostly useful for Objective-C metadata.

This is plumbing, so we don't have a use of it yet. More to come, etc.

Chris Lattner eaae8d0cdc Remove support for building LLVM libraries into "relinked" 
object files.  Now we always build LLVM libraries into archives (.a files).

This makes the 'make' build work more like the cmake build, among other

I think that llvm-config wasn't quite right for .o files anyway.

Bill Wendling f7b83c7ae7 Change MachineInstrBuilder::addReg() to take a flag instead of a list of

doing. Remembering what all of those booleans mean isn't easy, especially if you
aren't spending all of your time in that code.

I took Jakob's suggestion and made it illegal to pass in "true" for the
flag. This should hopefully prevent any unintended misuse of this (by reverting
to the old way of using addReg()).

Bill Wendling 084669a1c9 Second attempt: 
Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to
use the old behavior, the flag is -O0. This change allows for finer-grained
control over which optimizations are run at different -O levels.

Most of this work was pretty mechanical. The majority of the fixes came from
verifying that a "fast" variable wasn't used anymore. The JIT still uses a
"Fast" flag. I'll change the JIT with a follow-up patch.

Duncan Sands 12da8ce3d2 Introduce new linkage types linkonce_odr, weak_odr, common_odr 
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.
