Andrew Trick 39a99140c7 X86 itinerary properties. 
llvm-svn: 157981
 2012-06-05 03:44:46 +00:00
Andrew Trick b2680c718f ARM itinerary properties. 
llvm-svn: 157980
 2012-06-05 03:44:43 +00:00
Andrew Trick 73d7736b17 misched: Added MultiIssueItineraries. 
This allows a subtarget to explicitly specify the issue width and
other properties without providing pipeline stage details for every
instruction.

 2012-06-05 03:44:40 +00:00
Andrew Trick a88d46e818 sdsched: Use the right heuristics when -mcpu is not provided and we have no itinerary. 
Use ILP heuristics for long latency instrs if no scoreboard exists.

Andrew Trick ed7c96d7d9 misched: Allow disabling scoreboard hazard checking for subtargets with a 
valid itinerary but no pipeline stages.

An itinerary can contain useful scheduling information without specifying pipeline stages for each instruction.

Jakob Stoklund Olesen 345528944c Remove the last remat-related code from LiveIntervalAnalysis. 
Rematerialization is handled by LiveRangeEdit now.

 2012-06-05 01:06:15 +00:00
Jakob Stoklund Olesen 9e27e2621a Stop using LiveIntervals::isReMaterializable(). 
It is an old function that does a lot more than required by
CalcSpillWeights, which was the only remaining caller.

The isRematerializable() function never actually sets the isLoad
argument, so don't try to compute that.

Joel Jones 7f2ac7a2c8 Revert commit r157966 
llvm-svn: 157972
 2012-06-05 00:47:21 +00:00
Joel Jones d08534f82e This change handles a another case for generating the bic instruction 
when a compile time constant is known.  This occurs when implicitly zero 
extending function arguments from 16 bits to 32 bits.

Rafael Espindola 47d988c54c When gvn decides to replace an instruction with another, we have to patch the 
replacement to make it at least as generic as the instruction being replaced.
This includes:
* dropping nsw/nuw flags
* getting the least restrictive tbaa and fpmath metadata
* merging ranges

Fixes PR12979.

Jakob Stoklund Olesen 5ef0e0b262 Pass context pointers to LiveRangeCalc::reset(). 
Remove the same pointers from all the other LiveRangeCalc functions,
simplifying the interface.

Hans Wennborg 245917b536 MIPS TLS: use the model selected by TargetMachine::getTLSModel(). 
This was mostly done already in r156162, but I missed one place.

Hal Finkel 1de9bf01e4 Fix a copy-and-paste duplication error in the PPC 440 and A2 schedules (no functionality change).

 2012-06-04 02:39:52 +00:00
Hal Finkel 595817eebe Enable generating PPC pre-increment (r+imm) instructions by default. 
It seems that this no longer causes test suite failures on PPC64 (after r157159),
and often gives a performance benefit, so it can be enabled by default.

Rafael Espindola 34b9c511c1 Represent .rept as an anonymous macro. This removes the need for the ActiveRept

Benjamin Kramer 172f80849f Use access(2) instead of stat(2) to check if a file exists. 
Apart from being slightly cheaper, this fixes a real bug that hits 32 bit
linux systems. When passing a file larger than 2G to be linked (which isn't
that uncommon with large projects such as WebKit), clang's driver checks
if the file exists but the file size doesn't fit in an off_t and stat(2)
fails with EOVERFLOW. Clang then says that the file doesn't exist instead
of passing it to the linker.

Stepan Dyatkovskiy 0e46d8a08c PR1255: case ranges. 
IntRange converted from struct to class. So main change everywhere is replacement of ".Low/High" with ".getLow/getHigh()"
