* Fix compilation error on MSVC.Argyrios Kyrtzidis2008-10-041-1/+1
| | | | llvm-svn: 57046
* Fix fast-isel's handling of atomic instructions. They mayDan Gohman2008-10-041-1/+4
| | | | | | | | expand to multiple basic blocks, in which case fast-isel needs to informed of which block to use as it resumes inserting instructions. llvm-svn: 57040
* Fix a bug in the local allocator's liveness computation where itDan Gohman2008-10-041-3/+5
| | | | | | | | was setting kill flags on tied uses in two-address instructions. The kill flags were causing the allocator to think it could allocate the use and its tied def in different registers. llvm-svn: 57039
* Pass MemOperand through for 64-bit atomics on 32-bit,Dale Johannesen2008-10-031-5/+18
| | | | | | | incidentally making the case where the memop is a pointer deref work. Fix cmp-and-swap regression. llvm-svn: 57027
* Use -1ULL instead of uint64_t(-1), at Anton's suggestion.Dan Gohman2008-10-031-2/+2
| | | | llvm-svn: 57021
* Fix typos pointed out by Duncan. Also untabify these files.Evan Cheng2008-10-033-15/+15
| | | | llvm-svn: 57018
* Switch the MachineOperand accessors back to the short names likeDan Gohman2008-10-0324-132/+132
| | | | | | isReg, etc., from isRegister, etc. llvm-svn: 57006
* The result of getSetCCResultType (eg: i32) may be largerDuncan Sands2008-10-031-4/+8
| | | | | | | | | than the type an i1 is promoted to (eg: i8). Account for this. Noticed by Tilmann Scheller on CellSPU; he will hopefully take care of fixing this in LegalizeDAG and adding a testcase! llvm-svn: 56997
* Implement fast-isel support for zero-extending from i1.Dan Gohman2008-10-031-1/+12
| | | | | | | It turns out that this is a fairly common operation, and it's easy enough to handle. llvm-svn: 56990
* Optimize conditional branches in X86FastISel. This replacesDan Gohman2008-10-021-10/+18
| | | | | | | | | | | sequences like this: sete %al testb %al, %al jne LBB11_1 with this: je LBB11_1 llvm-svn: 56969
* Add a new MachineBasicBlock utility function, isLayoutSuccessor, thatDan Gohman2008-10-021-0/+5
| | | | | | | can be used when deciding if a block can transfer control to another via a fall-through instead of a branch. llvm-svn: 56968
* fix build gcc 4.3Andrew Lenharth2008-10-021-0/+1
| | | | llvm-svn: 56965
* Use a multimap rather than a map for holding the list of copies to insert, ↵Owen Anderson2008-10-021-12/+19
| | | | | | | | | | so we don't lose copies when two of them have the same source. I don't know what I was thinking when I wrote this originally. Note: There's probably a more efficient way to do this, but I need to think about it some more, and about what determinism guarantees need to be present. llvm-svn: 56964
* Handle some 64-bit atomics on x86-32, some of the time.Dale Johannesen2008-10-021-11/+16
| | | | llvm-svn: 56963
* A Partitioned Boolean Quadratic Programming (PBQP) based register allocator.Evan Cheng2008-10-023-0/+2208
| | | | | | Contributed by Lang Hames. llvm-svn: 56959
* Fix a think-o in isSafeToMove. This fixes it from thinking thatDan Gohman2008-10-021-1/+1
| | | | | | volatile memory references are safe to move. llvm-svn: 56948
* Remove OptimizeForSize global. Use function attribute optsize.Devang Patel2008-10-012-1/+5
| | | | llvm-svn: 56937
* Enable FastISel by default (on x86 and x86-64) with the -fast option.Dan Gohman2008-10-011-4/+16
| | | | llvm-svn: 56930
* Make some implicit conversions explicit, to avoid compiler warnings.Dan Gohman2008-10-011-2/+2
| | | | llvm-svn: 56927
* Fold trivial two-operand tokenfactors where the operands are equalDan Gohman2008-10-011-0/+1
| | | | | | immediately. llvm-svn: 56921
* Fix typos in comments.Dan Gohman2008-10-011-2/+2
| | | | llvm-svn: 56919
* Implement the -fno-builtin option in the front-end, not in the back-end.Bill Wendling2008-10-011-6/+1
| | | | llvm-svn: 56900
* Mark merged-in VNInfo's as being PHIKilled.Owen Anderson2008-09-301-0/+5

* - Initialize "--no-builtin" to "false".Bill Wendling2008-09-301-1/+1
| | | | | | - Testcase for r56885. llvm-svn: 56886
* Add the new `-no-builtin' flag. This flag is meant to mimic the GCCBill Wendling2008-09-301-1/+7
| | | | | | | | | `-fno-builtin' flag. Currently, it's used to replace "memset" with "_bzero" instead of "__bzero" on Darwin10+. This arguably violates the meaning of this flag, but is currently sufficient. The meaning of this flag should become more specific over time. llvm-svn: 56885
* Move the primary fast-isel top-level comments to FastISel.cpp, whereDan Gohman2008-09-301-0/+28
| | | | | | they'll be a little more visible. Also, update and reword them a bit. llvm-svn: 56877
* Optimize SelectionDAG's AssignTopologicalOrder even further.Dan Gohman2008-09-302-31/+66
| | | | | | | | | | | | | | | | | | | Completely eliminate the TopOrder std::vector. Instead, sort the AllNodes list in place. This also eliminates the need to call AllNodes.size(), a linear-time operation, before performing the sort. Also, eliminate the Sources temporary std::vector, since it essentially duplicates the sorted result as it is being built. This also changes the direction of the topological sort from bottom-up to top-down. The AllNodes list starts out in roughly top-down order, so this reduces the amount of reordering needed. Top-down is also more convenient for Legalize, and ISel needed only minor adjustments. llvm-svn: 56867
* Re-apply 56835 along with header file changes.Evan Cheng2008-09-303-8/+20
| | | | llvm-svn: 56848
* Revert commit 56835 since it breaks the build.Duncan Sands2008-09-303-20/+8
| | | | | | | | | | "If a re-materializable instruction has a register operand, the spiller will change the register operand's spill weight to HUGE_VAL to avoid it being spilled. However, if the operand is already in the queue ready to be spilled, avoid re-materializing it". llvm-svn: 56837

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | information is in an unreachable block, then it's possible that the high/low pc values won't be set for the dwarf information. E.g., this function: void abort(void) __attribute__((__noreturn__)); void dead_beef(void) __attribute__ ((noreturn)); int *b; void dead_beef(void) { *b=0xdeadbeef; abort(); } has a call to "@llvm.dbg.region.end" only in the unreachable block: define void @dead_beef() noreturn nounwind { entry: call void @llvm.dbg.func.start(...) call void @llvm.dbg.stoppoint(...) ... call void @abort( ) noreturn nounwind unreachable return: ; No predecessors! call void @llvm.dbg.stoppoint(...) call void @llvm.dbg.region.end(...) ret void } The dwarf information emitted is something like: 0x00000084: TAG_subprogram [5] AT_name( "dead_beef" ) AT_external( 0x01 ) AT_prototyped( 0x01 ) AT_decl_file( 0x01 ) AT_decl_line( 0x08 ) Note that this is *not* the best fix for this problem, but a band-aid for an gaping wound.
