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.

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

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.

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
