* [NFC] Header cleanupMehdi Amini2016-04-181-2/+0
| | | | | | | | | | | | | | Removed some unused headers, replaced some headers with forward class declarations. Found using simple scripts like this one: clear && ack --cpp -l '#include "llvm/ADT/IndexedMap.h"' | xargs grep -L 'IndexedMap[<]' | xargs grep -n --color=auto 'IndexedMap' Patch by Eugene Kosov <claprix@yandex.ru> Differential Revision: http://reviews.llvm.org/D19219 From: Mehdi Amini <mehdi.amini@apple.com> llvm-svn: 266595
* RegisterScavenger: Take a reference as enterBasicBlock() argument.Matthias Braun2016-04-061-2/+2
| | | | | | | Make it obvious that the argument cannot be nullptr. Remove an unnecessary nullptr check in initRegState. llvm-svn: 265511
* Change eliminateCallFramePseudoInstr() to return an iteratorHans Wennborg2016-03-311-10/+1
| | | | | | | | | | | | | | | | | | | | | This will become necessary in a subsequent change to make this method merge adjacent stack adjustments, i.e. it might erase the previous and/or next instruction. It also greatly simplifies the calls to this function from Prolog- EpilogInserter. Previously, that had a bunch of logic to resume iteration after the call; now it just continues with the returned iterator. Note that this changes the behaviour of PEI a little. Previously, it attempted to re-visit the new instruction created by eliminateCallFramePseudoInstr(). That code was added in r36625, but I can't see any reason for it: the new instructions will obviously not be pseudo instructions, they will not have FrameIndex operands, and we have already accounted for the stack adjustment.

* [WebAssembly] Implement prolog/epilog insertion and FrameIndex eliminationDerek Schuff2015-12-111-0/+1066
Summary: Use the SP32 physical register as the base for FrameIndex lowering. Update it and the __stack_pointer global var in the prolog and epilog. Extend the mapping of virtual registers to wasm locals to include the physical registers. Rather than modify the target-independent PrologEpilogInserter (which asserts that there are no virtual registers left) include a slightly-modified copy for Wasm that does not have this assertion and only clears the virtual registers if scavenging was needed (which of course it isn't for wasm).
