Bob Wilson ceffeb6abd Rename ARM "lane_cst" operands to "nohash_imm" since they are used for 
several things other than Neon vector lane numbers.  For inline assembly
operands with a "c" print code, check that they really are immediates.

Bob Wilson a70623102e Match VTRN, VZIP, and VUZP shuffles. Restore the tests for these operations, 
now using shuffles instead of intrinsics.

Owen Anderson 2dd877d12a Try again at privatizing the layout info map, with a rewritten patch. 
This preserves the existing behavior much more closely than my previous attempt.

Sanjiv Gupta 9ae3bcb79e Add a pass to do call graph analyis to overlay the autos and frame sections of 
leaf functions. This pass will be extended to color other nodes of the call tree 
as well in future.

 2009-08-21 06:52:44 +00:00
Bob Wilson 51c7aa04ec Remove Neon intrinsics for VZIP, VUZP, and VTRN. We will represent these as 
vector shuffles.  Temporarily remove the tests for these operations until the
new implementation is working.

Owen Anderson baa922cf16 Re-revert r79555. Apparently it's not just buildbot weirdness. 
llvm-svn: 79578

Sanjiv Gupta a874d82492 part of the previous commit for PIC16 ISR implementation. 
llvm-svn: 79563
 2009-08-20 19:34:18 +00:00
Sanjiv Gupta 686e9f55dc Implement support for ISRs. 
Clone functions that are shared between the Main thread and Interrupt thread.
CallSites are changed in AsmPrinter currently. A better solution would have been to modify the legalizer (SoftenFloat) to allow targets to change the name of libcalls for float operations. But that currently breaks other targets.
Also, cloing of automatic variables is done AsmPrinter, a better approach would
be to use the ValueMap in CloneFunction itself.

Owen Anderson d2354b8cc5 Make the StructType->StructLayout table private to TargetData, allowing us to avoid locking on it. 
llvm-svn: 79555
 2009-08-20 18:26:03 +00:00
Sean Callanan 46bb77f2cf Fixed PCMPESTRM128 to have opcode 0x60 instead of 0x62, as specified by the 
Intel documentation.

llvm-svn: 79554
 2009-08-20 18:24:27 +00:00
Dan Gohman 05046085b6 Fix an x86 code size regression: prefer RIP-relative addressing 
over absolute addressing even in non-PIC mode (unless the address
has an index or something else incompatible), because it has a
smaller encoding.

llvm-svn: 79553
 2009-08-20 18:23:44 +00:00
Evan Cheng 01de985ae6 Fix an obvious copy-n-paste bug. 
llvm-svn: 79535

Dan Gohman f91a992c30 Update and fix some comments.

Reid Kleckner 5c51639e3e Modify an assert to avoid what looks like a GCC 4.2.4 signed-ness bug. 
llvm-svn: 79494

Dale Johannesen 1d764f61ef Handle 'a' modifier in X86 asms. PR 4742.

Dan Gohman de255fc8f6 Remove temporary testing code. 
llvm-svn: 79443
 2009-08-19 18:27:08 +00:00
Dan Gohman ac33a9061d Add an x86 peep that narrows TEST instructions to forms that use 
a smaller encoding. These kinds of patterns are very frequent in
sqlite3, for example.

David Goodwin a7c2dfbca1 Update Cortex-A8 instruction itineraries for integer instructions. 
llvm-svn: 79436
 2009-08-19 18:00:44 +00:00
Bob Wilson 32cd8550ce Add support for Neon VEXT (vector extract) shuffles. 
This is derived from a patch by Anton Korzh.  I modified it to recognize
the VEXT shuffles during legalization and lower them to a target-specific
DAG node.

 2009-08-19 17:03:43 +00:00
Chris Lattner 4b7dadb76e eliminate AsmPrinter::SwitchToSection and just have clients 
talk to the MCStreamer directly instead.

Eric Christopher 9fe912de5f Implement sse4.2 string/text processing instructions: 
Add patterns and instruction encoding information.
Add custom lowering to deal with hardwired return register of
uncertain type (xmm0).

 2009-08-18 22:50:32 +00:00
Jakob Stoklund Olesen 36d747745e Simplify RegScavenger::FindUnusedReg. 
- Drop the Candidates argument and fix all callers. Now that RegScavenger
  tracks available registers accurately, there is no need to restict the
  search.
- Make sure that no aliases of the found register are in use. This was a potential bug.

Anton Korobeynikov e4d2e8465a Text sections should have 'exec' flag set. This seems to unbreak libstdc++ on linux. 
Patch by Dmitry Gorbachev!

Chris Lattner 966d32dffb remove some pointless null switchtosections. The IntelAsmPrinter doesn't really work anyway.
