* 64-bit fp loads can come straight out of the constant pool, not asEric Christopher2010-09-091-10/+18
| | | | | | bad as I'd thought. llvm-svn: 113561
* Discard metadata produced by LLVM 2.7. The value enumeration it usedDan Gohman2010-09-092-15/+45
| | | | | | | | | | | | | is different from what the code now uses in a two ways: NamedMDNodes were considered Values and included in the numbering, and the function-local metadata counter wasn't reset between functions. The later problem breaks lazy deserialization, so instead of trying to emulate the old numbering, just drop the old metadata. The only in-tree use case is debug info with LTO, where the QOI loss is considered acceptable. llvm-svn: 113557
* llvm-mc: Don't crash when using -n and we see a directive before the initial ↵Daniel Dunbar2010-09-091-0/+30

* llvm-mc: Make sure we exit != 0 if any errors are encountered.Daniel Dunbar2010-09-091-8/+10

* SIToFP and FPToSI conversions work only on fp-reg to fp-reg. MoveEric Christopher2010-09-091-7/+33
| | | | | | some data around and implement a couple of move routines to do this. llvm-svn: 113546
* MDNodes are not Constants.Dan Gohman2010-09-091-5/+0

* Print invalid metadata references as <badref>, for consistency withDan Gohman2010-09-091-2/+10

* "Strike that, reverse it." -- Mr. Wonka.Eric Christopher2010-09-091-2/+2
| | | | | | Truncate when truncating, extend when extending. llvm-svn: 113536
* What the loop unroller cares about, rather than just not unrolling loops ↵Owen Anderson2010-09-092-5/+11
| | | | | | | | | | | with calls, is not unrolling loops that contain calls that would be better off getting inlined. This mostly comes up when an interleaved devirtualization pass has devirtualized a call which the inliner will inline on a future pass. Thus, rather than blocking all loops containing calls, add a metric for "inline candidate calls" and block loops containing those instead. llvm-svn: 113535
* Add FPTrunc, fix some bugs where I forgot to update the value map.Eric Christopher2010-09-091-2/+28
| | | | llvm-svn: 113533
* Revert r113439, which relaxed the requirement that loops containing calls ↵Owen Anderson2010-09-091-4/+2
| | | | | | | | cannot be unrolled. After some discussion, there seems to be a better way to achieve the same effect. llvm-svn: 113528
* r113526 introduced an unintended change to the loop unrolling threshold. ↵Owen Anderson2010-09-091-1/+1
| | | | | | Revert it. llvm-svn: 113527
* Fix typo in code to cap the loop code size reduction calculation.Owen Anderson2010-09-091-2/+2
| | | | llvm-svn: 113526
* Use code-size reduction metrics to estimate the amount of savings we'll get ↵Owen Anderson2010-09-091-1/+24
| | | | | | | | when we unroll a loop. Next step is to recalculate the threshold values given this new heuristic. llvm-svn: 113525

* For each instruction itinerary class, specify the number of micro-ops eachEvan Cheng2010-09-096-8/+97
| | | | | | | | | | instruction in the class would be decoded to. Or zero if the number of uOPs must be determined dynamically. This will be used to determine the cost-effectiveness of predicating a micro-coded instruction. llvm-svn: 113513
* MCELF: Write relocation fragments in the right endian.Benjamin Kramer2010-09-091-5/+26
| | | | | | - This code is gross, but does the job for now. llvm-svn: 113509
* Make ELF OS ABI dependent on the OS from target triple.Roman Divacky2010-09-092-13/+25

* Move remaining MMX instructions from SSE to MMX.Dale Johannesen2010-09-092-107/+44

* Refactor code-size reduction estimation methods out of InlineCostAnalyzer ↵Owen Anderson2010-09-091-92/+90
| | | | | | | | | | | and into CodeMetrics. They don't use any InlineCostAnalyzer state, and are useful for other clients who don't necessarily want to use all of InlineCostAnalyzer's logic, some of which is fairly inlining-specific. No intended functionality change. llvm-svn: 113499

* Nuke whitespace and fix some indenting.Eric Christopher2010-09-091-60/+60

* Move most MMX instructions (defined as anything thatDale Johannesen2010-09-092-121/+136

* Simplify copying over operands from pseudo NEON load/store instructions.Bob Wilson2010-09-091-30/+19
| | | | | | | | For VLD3/VLD4 with double-spaced registers, add the implicit use of the super register for both the instruction loading the even registers and the instruction loading the odd registers. llvm-svn: 113452

* Very basic compare support.Eric Christopher2010-09-081-0/+48
| | | | llvm-svn: 113440
* Relax the "don't unroll loops containing calls" rule. Instead, when a loop ↵Owen Anderson2010-09-081-2/+4
| | | | | | | | | contains a call, lower the unrolling threshold to the optimize-for-size threshold. Basically, for loops containing calls, unrolling can still be profitable as long as the loop is REALLY small. llvm-svn: 113439
