 2010-08-19 23:25:16 +00:00
Owen Anderson bb723b228a When a set of bitmask operations, typically from a bitfield initialization, only modifies the low bytes of a value, 
we can narrow the store to only over-write the affected bytes.

Evan Cheng 361b9be7c6 It's possible to sink a def if its local uses are PHI's.

llvm-svn: 111483
 2010-08-19 00:09:07 +00:00
Chris Lattner 3decde9305 refix PR1143 by making basicaa analyze zexts of indices aggresively, 
which I broke with a recent patch.

llvm-svn: 111452
 2010-08-18 23:09:49 +00:00
Dan Gohman 492c2ea31e Add a testcase to verify that commands don't crash when they hit 
errors on stderr.

Daniel Dunbar 8e92d9b68d MC/ELF: Allow null values in virtual sections, ELF doesn't use special 
directives for putting contents in .bss, for example.

Kalle Raiskila e60b5161d1 Fix a bug with insertelement on SPU. 
The previous algorithm in LowerVECTOR_SHUFFLE 
didn't check all requirements for "monotonic" shuffles.

llvm-svn: 111361
 2010-08-18 10:20:29 +00:00
Kalle Raiskila ab49360f59 Remove all traces of v2[i,f]32 on SPU. 
The "half vectors" are now widened to full size by the legalizer.
The only exception is in parameter passing, where half vectors are 
expanded. This causes changes to some dejagnu tests.

llvm-svn: 111360
 2010-08-18 10:04:39 +00:00
Kalle Raiskila f3984d1ef6 Change SPU C calling convention to match that described in 
"SPU Application Binary Interface Specification, v1.9" by
IBM. 
Specifically: use r3-r74 to pass parameters and the return value.

llvm-svn: 111358

Chris Lattner a33edcb56c fix PR7589: In brief: 
gep P, (zext x) != gep P, (sext x)

DecomposeGEPExpression was getting this wrong, confusing
basicaa.

llvm-svn: 111350
 2010-08-18 04:25:43 +00:00
Chris Lattner 3c603024bb Fix PR7755: knowing something about an inval for a pred 
from the LHS should disable reconsidering that pred on the
RHS.  However, knowing something about the pred on the RHS
shouldn't disable subsequent additions on the RHS from
happening.

Bob Wilson fb7eaff759 Expand ZERO_EXTEND operations for NEON vector types. 
Testcase from Nick Lewycky.

Eric Christopher 51edc7b7e1 Temporarily revert r110987 as it's causing some miscompares in 
vector heavy code.  I'll re-enable when we've tracked down the problem.

llvm-svn: 111318

Dan Gohman ed2b005842 Tweak IVUsers' concept of "interesting" to exclude add recurrences 
where the step value is an induction variable from an outer loop, to
avoid trouble trying to re-expand such expressions. This effectively
hides such expressions from indvars and lsr, which prevents them
from getting into trouble.

Patch by Cameron Esfahani!

llvm-svn: 111287
 2010-08-17 21:05:54 +00:00
Dan Gohman 5047ca0c02 When rotating loops, put the original header at the bottom of the 
loop, making the resulting loop significantly less ugly.  Also, zap
its trivial PHI nodes, since it's easy.

llvm-svn: 111255
 2010-08-17 17:39:21 +00:00
Bob Wilson 942b10f511 Change ARM PKHTB and PKHBT instructions to use a shift_imm operand to avoid 
printing "lsl #0".  This fixes the remaining parts of pr7792.  Make
corresponding changes for encoding/decoding these instructions.

llvm-svn: 111251
 2010-08-17 17:23:19 +00:00

 2010-08-16 23:44:29 +00:00
Bob Wilson 804f6159f1 Generalize a pattern for PKHTB: an SRL of 16-31 bits will guarantee 
that the high halfword is zero.  The shift need not be exactly 16 bits.

Dan Gohman 250b754428 Instead, teach SimplifyCFG to trim non-address-taken blocks from 
indirectbr destination lists.

Dan Gohman fb83b043eb Revert r111058, the lint check for indirectbr successors that aren't 
address-taken. This can occur normally, if the code which took the
address got DCEd.
