2011-06-02PR10067: Add missing safety check to call return transformation in ↵Eli Friedman
MemCpyOpt::processStore. If something accesses the dest of the "copy" between the call and the copy, the performCallSlotOptzn transformation is not valid. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132485 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-02During post RA scheduling, do not try to chase reg defs. to preserve ↵Devang Patel
DBG_VALUEs. This approach has several downsides, for example, it does not work when dbg value is a constant integer, it does not work if reg is defined more than once, it places end of debug value range markers in the wrong place. It even causes misleading incorrect debug info when duplicate DBG_VALUE instructions point to same reg def. Instead, use simpler approach and let DBG_VALUE follow its predecessor instruction. After live debug value analysis pass, all DBG_VALUE instruction are placed at the right place. Thanks Jakob for the hint! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132483 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-02Use RegisterClassInfo::getOrder in RAFast.Jakob Stoklund Olesen
This saves two virtual function calls and an Allocatable BitVector test, making RAFast run 2% faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132471 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-02.cfi directive register parsing flexibility.Jim Grosbach
Parsing a register name/number for .cfi directives can't assume that a register name starts with a '%' token. Be more flexible and check for a register number instead. Still unlikely to be perfect, but it allows us to parse both plain identifiers as register names and integers as register numbers, which is what we're wanting to support at this point. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132466 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-02Add a RegisterClassInfo class that lazily caches information aboutJakob Stoklund Olesen
register classes. It provides information for each register class that cannot be determined statically, like: - The number of allocatable registers in a class after filtering out the reserved and invalid registers. - The preferred allocation order with registers that overlap callee-saved registers last. - The last callee-saved register that overlaps a given physical register. This information usually doesn't change between functions, so it is reused for compiling multiple functions when possible. The many possible combinations of reserved and callee saves registers makes it unfeasible to compute this information statically in TableGen. Use RegisterClassInfo to count available registers in various heuristics in SimpleRegisterCoalescing, making the pass run 4% faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132450 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-02When marking a block as being unanalyzable, use "Clobber" on the terminator ↵Eli Friedman
instead of the first instruction in the block. This is a bit of a hack; "Clobber" isn't really the right marking in the first place. memdep doesn't really have any way of properly expressing "unanalyzable" at the moment. Using it on the terminator is much less ambiguous than using it on an arbitrary instruction, though. In the given testcase, the "Clobber" was pointing to a load, and GVN was incorrectly assuming that meant that the "Clobber" load overlapped the load being analyzed (when they are actually unrelated). The included testcase tests both this commit and r132434. Part two of rdar://9429882. (r132434 was mislabeled.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132442 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-01In MemoryDependenceAnalysis::getNonLocalPointerDepFromBB, if a given block ↵Eli Friedman
is is deemed unanalyzable (and we execute one of the "goto PredTranslationFailure" statements), make sure we don't put information about the predecessors of that block into the returned data structures; this can lead to, among other things, extraneous results (which will confuse passes using memdep). Fixes an assert in GVN compiling ruby. Part of rdar://problem/9521954 . Testcase coming up soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132434 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-01Add an issue width check to the postRA scheduler. Patch by Max Kazakov!Andrew Trick
For targets with no itinerary (x86) it is a nop by default. For targets with issue width already expressed in the itinerary (ARM) it bypasses a scoreboard check but otherwise does not affect the schedule. It does make the code more consistent and complete and allows new targets to specify their issue width in an arbitrary way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132385 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-01The ARM stuff already calls the Resume function, not the Resume_or_Rethrow. ItBill Wendling
turns out that it could cause an infinite loop in some situations. If this code is triggered and it converts a cleanup into a catchall, but that cleanup was in already in a cleanup, then the _Unwind_SjLj_Resume could infinite loop. I.e., the code doesn't consume the exception object and passes it on to _Unwind_SjLj_Resume. But _USjLjR expects it to be consumed (since it's landing at a catchall instead of a cleanup). So it uses the values that are presently there, which are the values that tell it to jump to the fake landing pad. <rdar://problem/9508402> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132381 91177308-0d34-0410-b5e6-96231b3b80d8
