0cd78dd579 Cleanup: Clang warning fixes. 
No warnings left on a '-Wall' build except for a single tautological
compare in gen/asm-x86-32.h, which indeed seems like a bug.

289bb57adf Cleanup: Fix "braces around initializaion of subobject" warnings. 
The two ASM implementations should really be merged, as they
are very similar except for the added registers/instructions.

6e427fe818 Prefer C++-style casts. 
This is based on Item 2 of "More Effective C++". In general, the C++ cast operators are more expressive and easy to find,
e.g. by grep. Using const_cast also shuts up some compiler warnings.

72d510cb5e Emit floating-point integer quad word instructions with ll suffix. 
The LLVM MC backend doesn't recognize the q suffix, which was previously used.

See llvm.org/bugs/show_bug.cgi?id=11935.

If this turns out to be a speed problem, it could be done using char[3].

d0ea856024 Emit all D inline asm labels as local labels. 
On OS X, there is an actual significance to the distinction, which before lead e.g. to exception throwing in the below example being broken:

---
import core.exception;

void main() {
  asm {
    jmp Lfoo;
Lfoo:
    ;
  }
  throw cast(OutOfMemoryError)cast(void*)OutOfMemoryError.classinfo.init;
  assert(0);
}

a5b3dd29b5 Fixes 2 kinds of warnings. 
1) The last parameter of getGetElementPtr() has type bool. In some instances, a 2 is used as parameter. This is converted to true.
2) Several loops use int instead of unsigned. This causes warning about signed/unsigned mismatch.

Curiously, only Visual C++ complains about this. Nevertheless I think that the warnings should be fixed.

ff354d59b2 Use stringstream in asm generation instead of OutBuffer. 
Besides looking better, this should reduce allocations and copying.

c1bd2234a9 Clean up asm code a bit. 
- Use vector instead of Array, reducing allocations.
 - Use vectors instead of deques since we only push_back and index.
 - Remove redundant typedefs of iterators.
 - Comment out unused variable (used only in commented-out GDC code).
 - A few whitespace changes.

9705b7e017 Fixed problem accessing global variables from naked asm on osx. 2009-02-03 18:42:25 +01:00
Tomas Lindquist Olsen
dc5944df99 Implemented proper support for naked asm using llvm module level asm. Still not 100% complete, but already 1000 times better that what we had before. Don's BignumX86 implementation from Tango (when turned into a standalone unittest) seems to fully work with no changes, and great performance :) 
Fixed align N; in asm blocks.

Fixed inreg parameter passing on x86 for ref/out params.

Removed support for lazy initialization of function local static variables, I have no idea why I ever implemented this, it's not in the D spec, and DMD doesn't support it :P

Some of the global variable related changes might cause minor regressions, but they should be easily fixable.
