Bruno Cardoso Lopes fde21cfa64 Fix delay slot filler for non mips1 targets. Patch by Akira Hatanaka 
llvm-svn: 121376
 2010-12-09 17:31:11 +00:00
Douglas Gregor ff76cb9727 When an "inline" declaration was followed by a definition not marked 
"inline", we weren't giving the definition weak linkage because the
"inline" bit wasn't propagated. This was a longstanding FIXME that,
somehow, hadn't triggered a bug in the wild. Fix this problem by
tracking whether any declaration was marked "inline", and clean up the
semantics of GNU's "extern inline" semantics calculation based on this
change.

Fixes <rdar://problem/8740363>.

Chris Lattner fd51c52ef6 fix PR8753, eliminating a case where we'd infinitely make a 
substitution because it doesn't actually change the IR.  Patch by

Eric Christopher a8aaaee379 Rewrite the darwin tlv support to use a chain and return to copying 
the output to the correct register. Fixes a hidden problem uncovered
by the last patch where we'd try to DAG combine our MVT::Other node
oddly.

Jakob Stoklund Olesen e6dc3c899e IntervalMap iterators are heavyweight, so avoid copying them around and use 
references instead.

Similarly, IntervalMap::begin() is almost as expensive as find(), so use find(x)
instead of begin().advanceTo(x);

This makes RegAllocBasic run another 5% faster.

Bill Wendling 3392bfc8f3 The BLX instruction is encoded differently than the BL, because why not? In 
particular, the immediate has 20-bits of value instead of 21. And bit 0 is '0'
always. Going through the BL fixup encoding was trashing the "bit 0 is '0'"
invariant.

Attempt to get the encoding at slightly more correct with this.

Douglas Gregor aed2efbbb5 A typename specifier can end up referring to a unresolved using 
declaration that is a value in ill-formed code. Instead of crashing,
treat this as a dependent typename specifier and suggest that the
using add "typename" into the using declaration. Fixes <rdar://problem/8740998>.
