Evan Cheng 0f745da4fe Make use of target specific block size limits; bug fixes.

 2007-05-17 23:58:53 +00:00
Chris Lattner 0184f88deb disable MaskedValueIsZero, ComputeMaskedBits, and SimplifyDemandedBits for 
i128 integers.  The 64-bit masks are not wide enough to represent the results.
These should be converted to APInt someday.

 2007-05-17 18:19:23 +00:00
Chris Lattner 2135bc08d6 add expand support for ADDC/SUBC/ADDE/SUBE so we can codegen 128-bit add/sub on 32-bit (or less) targets 
llvm-svn: 37168
 2007-05-17 18:15:41 +00:00

Dale Johannesen 7a6c175e7a Don't fold bitconvert(load) for preinc/postdec loads. Likewise stores.

Duncan Sands 59ae77486c Output exception call-sites in address order, as required by the unwinding 
runtime.

 2007-05-16 12:12:23 +00:00
Chris Lattner 48fb92f75d Use a ptr set instead of a linear search to unique TokenFactor operands. 
This fixes PR1423

llvm-svn: 37102
 2007-05-16 06:37:59 +00:00
Evan Cheng 35fc2119b0 Devang points out that we need an assertion here. 
llvm-svn: 37097
 2007-05-16 05:11:10 +00:00
Evan Cheng 288f133c71 Bug fix: should check ABI alignment, not pref. alignment. 
llvm-svn: 37094
 2007-05-16 02:04:50 +00:00
Evan Cheng f5e53a58db Initial commit of (very basic) if converter.

 2007-05-15 17:05:43 +00:00
Duncan Sands 750e8c5d4d The index into the actions table is a ULEB128 not a SLEB128.

llvm-svn: 37069
 2007-05-15 01:33:58 +00:00
Evan Cheng 4d728b0419 Added getNumExplicitOperands and findFirstPredOperand.

Chris Lattner e49c974a7c implement a simple fneg optimization/propagation thing. This compiles: 
CodeGen/PowerPC/fneg.ll into:

_t4:
        fmul f0, f3, f4
        fmadd f1, f1, f2, f0
        blr

instead of:

_t4:
        fneg f0, f3
        fmul f0, f0, f4
        fmsub f1, f1, f2, f0
        blr

Evan Cheng e1595b6859 Only worry about intervening kill if there are more than one live ranges in the interval. 
llvm-svn: 37052
 2007-05-14 21:23:51 +00:00
Evan Cheng c690cba7d9 Fix for PR1406: 
v1 =
r2 = move v1
   = op r2<kill>
...
r2 = move v1
   = op r2<kill>

Clear the first r2 kill if v1 and r2 are joined.

Evan Cheng fc2377d4ed When marking a register as being implicitly defined, make sure to clear its partial use info as well.

 2007-05-14 20:39:18 +00:00
Reid Spencer 764ae2a21b Give names to the final result values of the part_set computations. This 
just aids in readability and debugability of the output. No functional change.

Anton Korobeynikov 1ee0c8d563 Emit function debug frames in one atom. This will prevent us from generating incorrect assembler in case of both 
debug information & exception information presented.

llvm-svn: 37019
 2007-05-13 17:30:11 +00:00
Anton Korobeynikov bbaf55448b Emit multiple common EH frames for multiple (including blank) personality 
functions. This partly fixes PR1414: now we're restricted only to one
personality function per eh frame, not per module. Further work on
"multiple personalities" topic needs representative example.

llvm-svn: 37018
 2007-05-13 15:42:26 +00:00
Anton Korobeynikov 13da17843c More DWARF-related things cleanup: 
1. Fix PR1380
2. Apply Duncan's patch from PR1410
3. Insert workaround for "one personality function per module" as noted in PR1414
4. Emit correct debug frames for x86/linux. This partly fixes DebugInfo/2006-11-06-StackTrace.cpp: stack trace is
shown correctly, but arguments for function on top of stack are displayed incorrectly.

 2007-05-11 08:23:57 +00:00
Dale Johannesen cc8f571bc8 Do not generate branches to entry block. This fixes several test suite 
failures on PPC (can happen only when prologue code is null)

Anton Korobeynikov ee02c7d2fb Ooops. Some debugging stuff :) 
llvm-svn: 36978

Anton Korobeynikov 96142de3f0 Allow multiple invokes per landing pad. This (probably) fixes PR1410.

Dale Johannesen 6e16d09252 Make tail merging handle many more cases (all it can, I think). 
llvm-svn: 36966
 2007-05-10 01:01:49 +00:00
Evan Cheng f325c2a65e Can't fold the bit_convert is the store is a truncating store. 
llvm-svn: 36962
 2007-05-09 21:49:47 +00:00
Anton Korobeynikov 192d09c2d9 Do not assert, when case range split metric is zero and JTs are not allowed: just emit binary tree in this case. This 
fixes PR1403.

Bill Wendling 31fd60ba0c Change names from RA to something unique to get rid of naming conflicts with 
certain linkers...

llvm-svn: 36910
 2007-05-07 21:36:06 +00:00
Evan Cheng a4cf58a103 Enable a couple of xforms: 
- (store (bitconvert v)) -> (store v) if resultant store does not require
higher alignment
- (bitconvert (load v)) -> (load (bitconvert*)v) if resultant load does not
require higher alignment

llvm-svn: 36908

Duncan Sands 671e8c4444 Parameter attributes on invoke calls were being lost due to the wrong 
attribute index being used.  Fix proposed by Anton Korobeynikov, who
asked me to implement and commit it for him.  This is PR1398.

Duncan Sands 00282a21a5 Use the personality function that was registered with MMI rather than 
hardwiring in the C++ one.

Chris Lattner 07e6f3257c Propagate alignment/volatility in two places. 
Implement support for expanding a bitcast from an illegal vector type to
a legal one (e.g. 4xi32 -> 4xf32 in SSE1).  This fixes PR1371 and
