d402cd382e Always add 'uwtable' attribute on x86_64. 
This is what Clang does, and omitting it could lead to problems
w.r.t. the System V ABI. Doesn't seem to have caused any issues
so far, though.

8d0749c394 Merge pull request #360 from klickverbot/union-initializer 
Unify struct initializer codegen, fix it for unions

1fed92b9b7 VarExp::toElem refactoring and global size assertion. 
Frontend errors shouldn't be used for glue layer consistency
checks – maybe the error was actually hit in ancient versions.

41e580a79f Get rid of now-obsolete DtoConstInitializerType. 2013-05-19 20:25:16 +02:00

eef05ba019 Do not try to guess exact initializer type. 
This might have been required with the old (pre-3.0) LLVM
type system, but the module linker handles global type
resolution just fine now.

Also, it is virtually impossible to determine the type in
advance for some cases, e.g. an array of unions with an
initializer that contains pointers to the array itself.

f8f405000b Avoid confusing naming convention. 
We generally do not really use underscore prefixes. But if
they are used in other codebases, they typically refer to
member variables.

b2ca861f64 Fixed ModuleInfo module name emission.

5742a0219c Fix inline asm labels in template functions. 
This is a giant kludge to avoid a redesign of the inline asm
handling code. I'd be glad if somebody came up with a better
solution.

GitHub: Fixes #340.

15fd67be03 Remove code for unimplemented goto-into-asm check. 
The check was never fully implemented. We need to look into
this again, as currently we fail with a fairly unintellegible
LLVM ICE (added as GitHub #).

a792ecbaf2 Fix function attribute handling on LLVM 3.3+. 
The issue was that when merging in the old attributes, attrs
wasn't assigned to, thus silently dropping all of them
(leading e.g. to noinline being omitted on functions containing
inline asm).

The new code hopefully also makes the intent clearer.

2e7884a80d Add support for new parameter attribute returned. 
Starting with LLVM 3.3 a new parameter attribute `returned` is supported.
The attribute states that the parameter is the return value, too. This is the
case in constructors. (Destructors and postblits do not return `this`.)
Attribute `returned` is now added to the `this` parameter of constructors.

bb5b60e591 Make '-O' equivalent to '-O3'. 
I have seen it used several times in benchmarks comparing it
to 'gdc -O3' and 'dmd -O -inline' now, so people apparently
expect it to yield the highest available optimization level.

46f8d999c5 Fix a LLVM 3.3 problem with debug info generation. 
In some cases an assertion is triggered because the debug context of a
local variale is verified. It turns out that LLVM returns always false
for DISubprogram.Verify() if the return type is not a composite type.
Reading the Clang source it looks like the return type must be a
subroutine type. This commit introduces a dummy subroutine type to
define the return type.

0b19b81ac9 Add new intrinsic LDC_never_inline. 
LDC_never_inline is a complementary intrinsic to LDC_allow_inline.
It tells the LLVM optimizer to never inline a function. This can be
useful if inlining creates incorrect code.
A possible application is core.thread.getStackTop().
