42b3da8ac7 Move function codegen data from IrFunction to new FuncGen. 
This change reduces memory consumption significantly by releasing the
memory held by the STL containers that are now inside FuncGen.

5ecdf1a70a Eliminate comparisons between GC allocations and constants. This removes some 
`assert(this !is null)`s when member functions get inlined.

Also tweak pass order a bit.

465f15eda0 Return void* from _d_allocclass so LLVM doesn't do weird things with it... 
This allows `-instcombine` followed by `-gvn` to do devirtualization, so add
`-gvn` in strategic places in the default pass order.

f13c5e82f5 Added a stripModifiers() function to remove shared|const|immutable storage classes in D2 (should eventually be moved to a dhelpers file rather than llvm helpers). 
Replaced a few occurances of STCinvariant with STCimmutable.

7dbe9baa37 Made is and !is use the same numeric comparison as == and !=, fixes #328 
Factored out common code from EqualExp and IdentityExp into
DtoBinNumericEquals in binexp.cpp.

4158fb474a Add an llvm::OStream workalike class for use with Logger::cout(), with the 
crucial difference being special handling of `llvm::Type`s so they get printed
by name rather than printing their full representation (which can be positively
*huge*).

This allows re-enabling some logger calls that were disabled due to extreme
verbosity.

dbe949ede6 More DtoType -> DtoTypeNotVoid for getting the array element llvm type. 2009-06-12 21:34:35 +02:00
Christian Kamm
1563c14e7a The llvm element type of void arrays should be i8 and not void. 
This caused DtoArrayCopyToSlice to fail when trying to get the size of
llvm-void for something like void[3] s = "abc"; inside a function.

25ebb3dbcd Generate less dead code by deleting unreachable blocks at the end of functions 
(which would otherwise appear if a function ends with a return, for example).

1f7a2a7884 Teach stack promotion to walk the CFG when a potential reuse of an allocation 
is found to see if it can actually happen instead of just assuming it will.

This allows it to catch cases like
{{{
int i;
Foo f;
while (cond(i))
    f = new Foo(i++);
return f.value;
}}}
where it previously wouldn't because a phi using the allocation would appear in
the condition block to propagate it to the use after the loop.

bf89205f7d Look for configuration file in /etc and /etc/ldc too (absolute paths) 
except on Windows. Also disabled the `$PREFIX/etc/ldc` case for Windows, since
the "/etc/ldc" part was #if'ed out anyway.

b999f679a7 Teach -dgc2stack to promote GC allocations in simple loops to stack 
allocations too. (A "simple" loop is one where the allocation isn't used in a
subsequent iteration)

This also means it's no longer necessary to run this pass multiple times.
Running it once after inlining should now catch all cases.

96650855ed Add a pass to strip the bodies of available_externally functions so string 
literals and `TypeInfo`s only referenced by them can be deleted by `-globaldce`.

Frits van Bommel
96fdcd6347 Run semantic3 on imported modules, and emit new symbols with 
`available_externally` linkage. This allows the inliner to inline functions from
other modules while telling the code generator to ignore those functions (treat
them as declarations)
Still generates a few extra `TypeInfo`s and strings...
Disabled when generating debug info because I don't really understand it, and it
doesn't like this.

b972dcb92d Add -memcpyopt to the optimization pass list. 2009-06-07 15:07:29 +02:00

f79e40a491 Use llvm.memset instead of _d_array_init_i1 and _d_array_init_i8. 
This exposes what's happening to LLVM, and memset is probably faster than the
runtime functions we were using anyway.

1958e17734 Rewrite StructLiteralExp::toElem to store individual fields instead of 
generating a constant to fill the entire struct with a single `store`.
This is much more efficient at compile time (fixing #320) and vastly reduces
the size of the emitted code. Since LLVM no longer needs to keep the data for
all fields in "registers" until the store happens, it should also be more
efficient at run time in cases where the fields aren't assigned with constants.

There's also some code clean-up by removing duplicated logic.

b4f8bd6e52 Fix #318 by making a list of all seen template instances in a module for 
singleobj compilation and then making sure they get emitted in their entirety.

f6997cb604 D2: 
Applied function type from D1 frontend that got removed in D2, it's critical for member function type to be correct.

Fixed a bunch of type discrepancies in druntime object.di vs. genobj.d .

Disabled (#if 0) some potentally very large type dumps for -vv .

Updated classinfo and typeinfo generation for D2, almost complete now.

Added finer grained checks for vtbl type mismatching, aids debugging.

cf5ad1a5b0 Remove some unnecessary #ifs. The D1 frontend has a Type::nextOf() which just 
returns `next`.
