* Make size computation less brittle.Rafael Espindola2011-05-274-73/+6
| | | | llvm-svn: 132222
* Add the suffix to the Win64 EH data sections' names if given. Add a test forCharles Davis2011-05-271-0/+22
| | | | | | this. XFAIL'd, because the COFF AsmParser can't handle .section yet. llvm-svn: 132220
* Refactor getActionType and getTypeToTransformTo ; place all of the 'decision'Nadav Rotem2011-05-274-6/+6
| | | | | | code in one place. Re-apply 131534 and fix the multi-step promotion of integers. llvm-svn: 132217
* Attempt to preserve debug line info in LICM; as the comment in the code ↵Eli Friedman2011-05-271-4/+14
| | | | | | | | says, it's hard to pick good line numbers for this transformation, but something is better than nothing. rdar://9143729 llvm-svn: 132215
* Don't use movw / movt for iOS static codegen for now to workaround some ↵Evan Cheng2011-05-271-1/+2
| | | | | | tools issues. rdar://9514789 llvm-svn: 132211
* CRC32 intrinsics were renamed at revision 132163. This submissionChad Rosier2011-05-271-5/+5
| | | | | | | | fixes aliasing issues with the old and new names as well as adds test cases for the auto-upgrader. Fixes rdar 9472944. llvm-svn: 132207
* Keep this simple. Use DIType to get signness and size of a type. Based on ↵Devang Patel2011-05-271-18/+13
| | | | | | size, select appropraite form. llvm-svn: 132206
* Add a parameter to the Win64 EH section getters to get a section with aCharles Davis2011-05-272-10/+40
| | | | | | | | | | suffix (e.g. .xdata$myfunc). The suffix part isn't implemented yet, but I'll get to it in the next patch. Fix up all callers of the affected functions. Make them pass said suffix to the function. llvm-svn: 132205
* Update this comment.Dan Gohman2011-05-271-1/+3
| | | | llvm-svn: 132202
* Don't sink or hoist debug info instrinsics; it isn't useful. This also ↵Eli Friedman2011-05-271-3/+6
| | | | | | | | prevents LICM sinking from erasing debug intrinsics which don't dominate any exit block of the loop. rdar://9143943 . llvm-svn: 132201
* Fix the inliner to maintain the current de facto invoke semantics:John McCall2011-05-271-42/+155
| | | | | | | | | | | | | | - the selector for the landing pad must provide all available information about the handlers, filters, and cleanups within that landing pad - calls to _Unwind_Resume must be converted to branches to the enclosing lpad so as to avoid re-entering the unwinder when the lpad claimed it was going to handle the exception in some way This is quite specific to libUnwind-based unwinding. In an effort to not interfere too badly with other unwinders, and with existing hacks in frontends, this only triggers on _Unwind_Resume (not _Unwind_Resume_or_Rethrow) and does nothing with selectors if it cannot find a selector call for either lpad. llvm-svn: 132200
* Delete MethodBodies that only filtered reserved registers.Jakob Stoklund Olesen2011-05-271-111/+0
| | | | | | | The register allocators know to filter reserved registers from the allocation orders, so we don't need all of this boilerplate. llvm-svn: 132199
* Handle signed types gracefully.Devang Patel2011-05-271-9/+21
| | | | | | This fixes regressions reported by buildbots as a fallout of r132193. llvm-svn: 132197
* Oops, wasn't intending to commit this. Partial revert of r132194.Eli Friedman2011-05-271-6/+9
| | | | llvm-svn: 132195
* Fix a silly mistake (which trips over an assertion) in r132099. rdar://9515076Eli Friedman2011-05-272-9/+8
| | | | llvm-svn: 132194
* Select DW_AT_const_value size based on variable size.Devang Patel2011-05-273-5/+15
| | | | llvm-svn: 132193
* Remove DwarfRegNum from the individual bits of the condition register.Rafael Espindola2011-05-271-32/+32
| | | | | | These should be DW_OP_bit_piece of CR (64). llvm-svn: 132192
* Remove DwarfRegNum from CARRY. I should be encoded with DW_OP_bit_piece.Rafael Espindola2011-05-271-1/+1
| | | | llvm-svn: 132190
* Assorted fixes for Win64 EH unwind info emission:Charles Davis2011-05-271-16/+29
| | | | | | | | | | - Flip order of bitfields. This gets our output matching GAS. - Handle case where the end of the prolog wasn't specified. - If the resulting unwind info struct is less than 8 bytes, pad to 8 bytes. Add a test for the latter two. llvm-svn: 132188
* Remove dwarf numbers from subregs. We should use DW_OP_bit_piece toRafael Espindola2011-05-271-45/+45
| | | | | | | | refer to them. I tested this with both check-all and the gdb testsuite. llvm-svn: 132187
* InstCombine: Make switch folding with equality compares more aggressive by ↵Benjamin Kramer2011-05-271-15/+54
| | | | | | | | trying instsimplify on the arm where we know the compared value. Stuff like "x == y ? y : x&y" now folds into "x&y". llvm-svn: 132185
* Fix PR10029 - VerifyCoalescing failure on patterns_dfa.c of 445.gobmk.Cameron Zwarich2011-05-271-2/+5
| | | | llvm-svn: 132181
* Make the branch encoding for tBcc more obvious that it's a 4-byte opcodeEric Christopher2011-05-272-1/+5
| | | | | | followed by a conditional and imm8. llvm-svn: 132179
* Fix comment.Eric Christopher2011-05-271-1/+1
| | | | llvm-svn: 132178
* Start keeping track of where the various unwind instructions are in the prolog.Charles Davis2011-05-272-22/+39
| | | | | | | Use them to calculate the offset inside the prolog. Emit this value when emitting the unwind codes. llvm-svn: 132177
* Add missing break statements. Align UNWIND_INFO and RUNTIME_FUNCTION structsCharles Davis2011-05-271-0/+6
| | | | | | | | to 4 bytes. I'm surprised no one caught the missing break statements. llvm-svn: 132176
* My attempt at fixing the leak reported by the valgrind buildbots. Valgrind willCharles Davis2011-05-271-2/+4
| | | | | | | | still report leaks, but they're spurious now. Valgrind cannot peer into std::vector objects--or any dynamic array, for that matter--because it doesn't know how big the array is. llvm-svn: 132174
* Fix inverted conditional in SaveReg and SaveXMM. Err when the frame pointer isCharles Davis2011-05-271-3/+7
| | | | | | | already defined, and err when the PushMachFrame operation isn't the first operation (if specified at all). llvm-svn: 132173
* One more debug line number miss in instcombine (although the code in ↵Eli Friedman2011-05-271-5/+1
| | | | | | question isn't actually in instcombine). llvm-svn: 132170
* Final step of instcombine debuginfo; switch a couple more places over to ↵Eli Friedman2011-05-275-16/+34
| | | | | | InsertNewInstWith, and use setDebugLoc for the cases which can't be easily handled by the automated mechanisms. llvm-svn: 132167
* Fix warning about || and && without explicit grouping.Chandler Carruth2011-05-261-2/+2
| | | | | | | | This looks like it flagged an actual bug. Devang, please review. I added the parentheses that change behavior, but make the behavior more closely match commit log's intent. llvm-svn: 132165
* Do not insert anything after terminator.Devang Patel2011-05-261-1/+2
| | | | llvm-svn: 132164
* Renamed llvm.x86.sse42.crc32 intrinsics; crc64 doesn't exist. Chad Rosier2011-05-264-25/+51
| | | | | | | crc32.[8|16|32] have been renamed to .crc32.32.[8|16|32] and crc64.[8|16|32] have been renamed to .crc32.64.[8|64]. llvm-svn: 132163
* Do not move DBG_VALUE in middle of PHI nodes.Devang Patel2011-05-261-1/+4
| | | | llvm-svn: 132161
* If llvm.dbg.value and the value instruction it refers to are far apart then ↵Devang Patel2011-05-261-1/+13
| | | | | | iSel may not be able to find corresponding Node for llvm.dbg.value during DAG construction. Make iSel's life easier by removing this distance between llvm.dbg.value and its value instruction. llvm-svn: 132151
* Add comment.Devang Patel2011-05-261-0/+3
| | | | llvm-svn: 132149
* During branch folding avoid inserting redundant DBG_VALUE machine instructions.Devang Patel2011-05-261-0/+13

* Test .seh_startchained and .seh_endchained parsing.Charles Davis2011-05-261-13/+13
| | | | | | | | | | | Rework how the MCWin64EHUnwindInfo instances are stored. Fix issues with chained unwind areas exposed by the test that were related to this. The ChainedParent field had the wrong address, because when the chained unwind info was added, the addresses shifted around. Now we store the pointers to the structures, which are now allocated from the MC heap. llvm-svn: 132106
* Correctly handle a one-word struct passed byval on x86_64.Stuart Hastings2011-05-263-15/+81

* indvars: incremental fixes for -disable-iv-rewrite and testcases.Andrew Trick2011-05-261-21/+72
| | | | | | | | Use a proper worklist for use-def traversal without holding onto an iterator. Now that we process all IV uses, we need complete logic for resusing existing derived IV defs. See HoistStep. llvm-svn: 132103
