arguments at the same offset, since it's needed when creating the empty
DeclRefExpr when deserializing. Fixes a memory corruption issue that would lead
to random bugs and crashes.

Reinstate r127112, "Propagate new-style exception spec information to ExtProtoInfo.", this time with the missing header.

conversion function when we're binding the result to a reference, drop
cv-qualifiers on the type we're referring to, since we should be
deducing a type that can be adjusted (via cv-qualification) to the
requested type. Fixes PR9336, and the remaining Boost.Assign failure.

the value splatted into every element. Extend this to getTrue and getFalse which
by providing new overloads that take Types that are either i1 or <N x i1>. Use
it in InstCombine to add vector support to some code, fixing PR8469!

It seems missing "clang/Basic/ExceptionSpecificationType.h".

template name as the result of substitution. The qualifier is handled
separately by the tree transformer, so we would end up in an
inconsistent state.

This is actually the last bit of PR9016, and possibly also fixes
PR8965. It takes Boost.Icl from "epic fail" down to a single failure.

llvm-svn: 127108

Revert r127073: "Introduce $(ECHOPATH) to print DOSish path string on MSYS bash for alternative of $(ECHO)."

It broke the llvm-gcc-native-mingw32 buildbot, and we need all of them to be green for the 2.9 branch.

Takumi, please reapply after we branch, preferably with a fix ;-)

ARM assembler stuff is crazy: for .setfp positive values of offset corresponds to "add" instruction, not to "sub" as in .pad case

llvm-svn: 127106

In Thumb1 mode the constant might be materialized via the load from constpool. Emit unwinding information in case when this load from constpool is used to change the stack pointer in the prologue.

llvm-svn: 127105

Implement frame unwinding information emission for Thumb1. Not finished yet because there is no way given the constpool index to examine the actual entry: the reason is clones inserted by constant island pass, which are not tracked at all! The only connection is done during asmprinting time via magic label names which is really gross and needs to be eventually fixed.

This is just very first approximation how the stuff should be done
(e.g. ARM-only for now). More to follow.

The coalescer can in very rare cases leave too large live intervals around after
rematerializing cheap-as-a-move instructions.

Linear scan doesn't really care, but live range splitting gets very confused
when a live range is killed by a ghost instruction.

I will fix this properly in the coalescer after 2.9 branches.

template (not a specialization!), use the "injected" function template
arguments, which correspond to the template parameters of the function
template. This is required when substituting into the default template
parameters of template template parameters within a function template.

Fixes PR9016.

llvm-svn: 127092

transform the type that replaces the template type parameter. In the
vast majority of cases, there's nothing to do, because most template
type parameters are replaced with something non-dependent that doesn't
need further transformation. However, when we're dealing with the
default template arguments of template template parameters, we might
end up replacing a template parameter (of the template template
parameter) with a template parameter of the enclosing template. 
 
This addresses part of PR9016, but not within function
templates. That's a separate issue.

This makes lookup slightly more expensive but it's worth it, unused
DenseMaps are common in LLVM code apparently.

that at cc1 level we will always have normalized triple and thus can
provide necessary default based on e.g. environment value (e.g. for
"arm-eabi" triple, etc.)
