Chad Rosier a281afc676 Fix a regression from r147481.
Original commit message from r147481:
DAGCombine for transforming 128->256 casts into a vmovaps, rather
then a vxorps + vinsertf128 pair if the original vector came from a load.

Fix:
Unaligned loads need to generate a vmovups.

Chad Rosier f5e086f18e Prevent obscure and incorrect tail-call optimization.
In this instance we are generating the tail-call during legalizeDAG.  The 2nd
floor call can't be a tail call because it clobbers %xmm1, which is defined by
the first floor call.  The first floor call can't be a tail-call because it's
not in the tail position.  The only reasonable way I could think to fix this
in a target-independent manner was to check for glue logic on the copy reg.

2012-02-28 15:36:07 +00:00
Evan Cheng 87c7b09d8d Some ARM implementaions, e.g. A-series, does return stack prediction. That is,
the processor keeps a return addresses stack (RAS) which stores the address
and the instruction execution state of the instruction after a function-call
type branch instruction.

Calling a "noreturn" function with normal call instructions (e.g. bl) can
corrupt RAS and causes 100% return misprediction so LLVM should use a
unconditional branch instead. i.e.
mov lr, pc
b _foo
The "mov lr, pc" is issued in order to get proper backtrace.

NAKAMURA Takumi bdf94879df Target/X86: Fix assertion failures and warnings caused by r151382 _ftol2 lowering for i386-*-win32 targets. Patch by Joe Groff.
[Joe Groff] Hi everyone. My previous patch applied as r151382 had a few problems:
Clang raised a warning, and X86 LowerOperation would assert out for
fptoui f64 to i32 because it improperly lowered to an illegal
BUILD_PAIR. Here's a patch that addresses these issues. Let me know if
any other changes are necessary. Thanks.

Kevin Enderby 6fbcd8d439 Updated the llvm-mc disassembler C API to support for the X86 target.
rdar://10873652

As part of this I updated the llvm-mc disassembler C API to always call the
SymbolLookUp call back even if there is no getOpInfo call back.  If there is a
getOpInfo call back that is tried first and then if that gets no information
then the  SymbolLookUp is called.  I also made the code more robust by
memset(3)'ing to zero the LLVMOpInfo1 struct before then setting
SymbolicOp.Value before for the call to getOpInfo.  And also don't use any
values from the  LLVMOpInfo1 struct if getOpInfo returns 0.  And also don't
use any of the ReferenceType or ReferenceName values from SymbolLookUp if it
returns NULL. rdar://10873563 and rdar://10873683

For the X86 target also fixed bugs so the annotations get printed. 

Also fixed a few places in the ARM target that was not producing symbolic
operands for some instructions.  rdar://10878166

Jakob Stoklund Olesen bc6ba479b6 Remove the YMM_HI_6_15 hack.
Call clobbers are now represented with register mask operands.  The
regmask can easily represent the fact that xmm6 is call-preserved while
ymm6 isn't.  This is automatically computed by TableGen from the
CalleeSavedRegs containing xmm6.

2012-02-16 17:56:02 +00:00
Jakob Stoklund Olesen 8a450cb2fa Enable register mask operands for x86 calls.
Call instructions no longer have a list of 43 call-clobbered registers.
Instead, they get a single register mask operand with a bit vector of
call-preserved registers.

This saves a lot of memory, 42 x 32 bytes = 1344 bytes per call
instruction, and it speeds up building call instructions because those
43 imp-def operands no longer need to be added to use-def lists. (And
removed and shifted and re-added for every explicit call operand).

Passes like LiveVariables, LiveIntervals, RAGreedy, PEI, and
BranchFolding are significantly faster because they can deal with call
clobbers in bulk.

Overall, clang -O2 is between 0% and 8% faster, uniformly distributed
depending on call density in the compiled code.  Debug builds using
clang -O0 are 0% - 3% faster.

I have verified that this patch doesn't change the assembly generated
for the LLVM nightly test suite when building with -disable-copyprop
and -disable-branch-fold.

Branch folding behaves slightly differently in a few cases because call
instructions have different hash values now.

Copy propagation flushes its data structures when it crosses a register
mask operand. This causes it to leave a few dead copies behind, on the
order of 20 instruction across the entire nightly test suite, including
SPEC. Fixing this properly would require the pass to use different data
structures.

Allows command line overrides to be centralized in LLVMTargetMachine.cpp.
LLVMTargetMachine can intercept common passes and give precedence to command line overrides.
Allows adding "internal" target configuration options without touching TargetOptions.
Encapsulates the PassManager.
Provides a good point to initialize all CodeGen passes so that Pass ID's can be used in APIs.
Allows modifying the target configuration hooks without rebuilding the world.

Andrew Trick 8523b16ff5 Instruction scheduling itinerary for Intel Atom.
Adds an instruction itinerary to all x86 instructions, giving each a default latency of 1, using the InstrItinClass IIC_DEFAULT.

Sets specific latencies for Atom for the instructions in files X86InstrCMovSetCC.td, X86InstrArithmetic.td, X86InstrControl.td, and X86InstrShiftRotate.td. The Atom latencies for the remainder of the x86 instructions will be set in subsequent patches.

Adds a test to verify that the scheduler is working.

Also changes the scheduling preference to "Hybrid" for i386 Atom, while leaving x86_64 as ILP.

Jakob Stoklund Olesen fc9dce25f7 Handle call-clobbered ymm registers on Win64.
The Win64 calling convention has xmm6-15 as callee-saved while still
clobbering all ymm registers.

Add a YMM_HI_6_15 pseudo-register that aliases the clobbered part of the
ymm registers, and mark that as call-clobbered.  This allows live xmm
registers across calls.

This hack wouldn't be necessary with RegisterMask operands representing
the call clobbers, but they are not quite operational yet.

Victor Umansky 5f29b0e57b Fix for the following bug in AVX codegen for double-to-int conversions:
.	"fptosi" and "fptoui" IR instructions are defined with round-to-zero rounding mode.
.	Currently for AVX mode for <4xdouble> and <8xdouble>  the "VCVTPD2DQ.128" and "VCVTPD2DQ.256" instructions are selected (for .fp_to_sint. DAG node operation ) by AVX codegen. However they use round-to-nearest-even rounding mode.
.	Consequently, the conversion produces incorrect numbers.
 
The fix is to replace selection of VCVTPD2DQ instructions with VCVTTPD2DQ instructions. The latter use truncate (i.e. round-to-zero) rounding mode. 
As .fp_to_sint. DAG node operation is used only for lowering of  "fptosi" and "fptoui" IR instructions, the fix in X86InstrSSE.td definition file doesn.t have an impact on other LLVM flows.
 
The patch includes changes in the .td file, LIT test for the changes and a fix in a legacy LIT test (which produced asm code conflicting with LLVN IR spec).
