Bob Wilson 53149401ee Combine the code to build VLDM and VSTM instructions, since they are 
mostly the same.

Devang Patel ad591dc6af Do not overestimate code size reduction in presense of debug info. 
Use CodeMetrics.analyzeBasicBlock() to estimate BB size.

John McCall 44c064be73 Check compatibility of vector types using their canonicalizations. 
Fixes an assertion arising C overload analysis, but really I can't imagine
that this wouldn't cause a thousand other uncaught failures.

Fixes PR6600.

Jeffrey Yasskin f6442f80cb Allow users to set CPPFLAGS and CXXFLAGS on the make command line. 
Tested: make CPPFLAGS=-m64 CXXFLAGS=-m64 -j8 && (cd tools/clang;make test)

Daniel Dunbar 12f1e32d59 MC/Mach-O: Implement initial support for relaxation. 
- The implementation is currently very brain dead and inefficient, but I have a
   clear plan on how to fix it.

 - The good news is, it works and correctly assembles 403.gcc (when built with
   Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g',
   the resulting binary is exactly equivalent to that when built with the system
   assembler. So it probably works! :)

Fariborz Jahanian c6140734c5 Fix a rare corner case bug which exposed a serious block API generation 
when initialized variable is a byref block variable and is referenced recursively
in the initializer (you guessed it, it is block implementation of
fibonacci number). Fix, on the other hand is trvial, by generating the
API for byref variable before API for its initializer. We will have this
test added to our internal test suite as a clang-style test is not possible
due to very convoluted IR sequence. Fixes radar 7745514.

 2010-03-12 21:09:07 +00:00

definitions.

 2010-03-12 19:04:14 +00:00
Chris Lattner be3242b523 finally give Mangler a getSymbol method, which returns an MCSymbol 
for a global instead of messing around with string buffers.

 2010-03-12 18:49:32 +00:00
Chris Lattner d75813970a simplify code to use OutContext.GetOrCreateTemporarySymbol with 
no arguments instead of having to come up with a unique name.
This also makes the code less fragile.

llvm-svn: 98364
 2010-03-12 18:47:50 +00:00
Chris Lattner 2eff505fba make the mangler take an MCContext instead of an MAI. 
No functionality change.

John McCall f3cd665d5a Remember whether a ParmVarDecl was spelled with a default argument or 
whether it inherited one from a previous declaration.

Patch by Enea Zaffanella!

Jeffrey Yasskin 35b4e4f641 Free DbgScopes in DwarfDebug::endFunction(). Also increased the const-ness of 
several fields to make it easier to figure out where bugs might be creeping in.

Duncan Sands 03fcbcf407 Revert turning copysignl into a COPYSIGN node for the moment: 
ppc calls copysignl with a 128 bit ppc long double, resulting
in a node that the type legalizer doesn't know how to expand.

Benjamin Kramer d69ee90f2f Use StringRef::substr instead of std::string::substr to avoid using a free'd 
string temporary. This should fix PR6590.

Duncan Sands 4c55f76936 Fix PR6522: implement copysign expansion for x86 long double 
(it seems that FreeBSD doesn't have copysignl).  Done by
removing a bunch of assumptions from the code.  This may also
help with sparc 128 bit floats.

llvm-svn: 98346
 2010-03-12 11:45:06 +00:00
Kovarththanan Rajaratnam 00682a48f4 Reintroduce r98340 and r98341 now without copy/paste errors.
