0ee2f34611 Don't use llvm::getGlobalContext() anymore 2009-07-13 20:16:15 +02:00
Benjamin Kramer
331319dab1 Build fix for the latest LLVMContext changes (LLVM r75445) 
This shouldn't break the build with older LLVM revs. We include
LLVMContext.h in gen/llvm.h now to make the transition a little bit
easier.

72d1f1e6dd Make the auto storage class never have the same meaning as scope. 
This changes the meaning of
auto class MyClass {} and
auto MyClass ident;
Both have been made an error to prevent accidents.

756a2cb2a1 Adjust LDC to work with the LLVMContext LLVM changes. 
This means we now require a fairly new LLVM revision. I use 75234.

feaefc3314 Better error handling for CMake LLVM config file detection. 2009-07-03 18:49:42 +02:00
Benjamin Kramer
22b36384b0 Fix build for LLVM >= r74640 
Some LLVM objects now take a 'Context' to make multi-threaded apps easier.
Since we're not multi-threaded it's safe to use llvm::getGlobalContext()
which gives us the same behavior as we had before.

151e266deb Yet another fix for finding llvm's config file. 
Since llvm-config --includedir sometimes includes the trailing llvm/ and
sometimes it doesn't, we just check both directories.

88f6e9e83a Initialize LLVM target and asmprinter for the native and extra targets. 
Uses some CMake hackery to get the native LLVM target name, since it only
provides a conveniance function for initializing the native target and not the
native asmprinter.

8e8837737a Be a little less overzealous with arrays of void-initialized typedefs; 
initialize `new VoidTD[][](2)` and `new VoidTD[][][](2, 3)` (but not
`new VoidTD[2][3]`, which is a dynamic array of static arrays of
void-initialized typedefs).

265cbea170 Make == for associative arrays test for equality, not identity. 
_aaEq was added to runtime/internal/aaA.d which forwards to
TypeInfo_AssociativeArray.equals in genobj.d. On the codegen side, DtoAAEquals
was added to gen/aa.cpp and is called from EqualExp::toElem in gen/toir.cpp.

I assume that the frontend will produce an error if == is used on associative
arrays of different type.

This fixes DMD bug 1429.

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.

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.

723cfef519 Another shot at fixing the issues with (constant) struct literals and their addresses. See DMD2682, #218, #324. 
The idea is to separate the notion of const from 'this variable can always be
replaced with its initializer' in the frontend. To do that, I introduced
Declaration::isSameAsInitializer, which is overridden in VarDeclaration to
return false for constants that have a struct literal initializer.

So
{{{
const S s = S(5);
void foo() { auto ps = &s; }
// is no longer replaced by
void foo() { auto ps = &(S(5)); }
}}}

To make taking the address of a struct constant with a struct-initializer
outside of function scope possible, I made sure that AddrExp::optimize doesn't
try to run the argument's optimization with WANTinterpret - that'd again
replace the constant with a struct literal temporary.

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.

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

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.
