Chris Lattner 6c234bf58f add a simple hack

 2007-12-24 19:27:46 +00:00
Gordon Henriksen 84c7325ca1 Setting GlobalDirective in TargetAsmInfo by default rather than 
providing a misleading facility. It's used once in the MIPS backend
and hardcoded as "\t.globl\t" everywhere else.

Scott Michel 5f1470f03a More working CellSPU tests: 
- vec_const.ll: Vector constant loads
- immed64.ll: i64, f64 constant loads

 2007-12-20 00:44:13 +00:00
Dale Johannesen eadbf4b91c Enable EH on PPC Darwin. This basically works; there 
are a couple of issues that show up with the optimizer,
but I don't think they're really EH problems.
(llvm-gcc testsuite users note:  By default the testsuite
uses the unwinding code that's built as part of your local
llvm-gcc, which does not work.  You need to trick it into
using the installed system unwinding code to get useful
results.)

Scott Michel 5ecac82f71 CellSPU testcase, extract_elt.ll: extract vector element. 
llvm-svn: 45219
 2007-12-19 21:17:42 +00:00
Scott Michel 098c113bc8 Two more test cases: or_ops.ll (arithmetic or operations) and vecinsert.ll 
(vector insertions)

llvm-svn: 45216
 2007-12-19 20:15:47 +00:00
Scott Michel 9b834469e0 Add new immed16.ll test case, fix CellSPU errata to make test case work. 
llvm-svn: 45196
 2007-12-19 07:35:06 +00:00
Bill Wendling ca77ecb40a Mark the "isRemat" instruction as never having side effects. 
llvm-svn: 45190
 2007-12-19 06:07:48 +00:00
Chris Lattner 2583a66295 add an obvious load folding missed optzn. 
llvm-svn: 45161
 2007-12-18 16:48:14 +00:00
Christopher Lamb 8b09a464b4 Fold certain additions through selects (and their compares) so as to eliminate subtractions. This code is often produced by the SMAX expansion in SCEV. 
This implements test/Transforms/InstCombine/2007-12-18-AddSelCmpSub.ll

 2007-12-18 09:34:41 +00:00
Chris Lattner 52a9e40789 add a missed case. 
llvm-svn: 45141
 2007-12-18 01:19:18 +00:00
Bill Wendling b3d85a5d4b Add "mayHaveSideEffects" and "neverHasSideEffects" flags to some instructions. I 
based what flag to set on whether it was already marked as
"isRematerializable". If there was a further check to determine if it's "really"
rematerializable, then I marked it as "mayHaveSideEffects" and created a check
in the X86 back-end similar to the remat one.

Scott Michel c5cccb9e60 - Restore some i8 functionality in CellSPU 
- New test case: nand.ll

llvm-svn: 45130
 2007-12-17 22:32:34 +00:00
Bill Wendling a2401be121 LD_Fp64m should have "isRematerializable" set. 
llvm-svn: 45128
 2007-12-17 22:17:14 +00:00
Bill Wendling 939526a930 As per feedback, revised comments to (hopefully) make the different side effect 
flags clearer.

Christopher Lamb edf0788758 Change the PointerType api for creating pointer types. The old functionality of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space. 
llvm-svn: 45082

Chris Lattner 2af27c202c don't violate C TBAA rules, use FloatToBits instead. 
llvm-svn: 45076
 2007-12-16 20:41:33 +00:00
Chris Lattner e3b05fe31b fix a questionable cast, thanks to Mike Stump for pointing this out. 
llvm-svn: 45075
 2007-12-16 20:26:54 +00:00
Chris Lattner dab6bd902e Fix the JIT encoding of cmp*ss, which aborts with this assertion currently: 
X86CodeEmitter.cpp:378: failed assertion `0 && "Immediate size not set!"'

I *think* this is right, but Evan, please verify.  It also looks like
CMPSDrr and maybe others are missing this info.  Evan, plz investigate.

Evan Cheng 23d2d4dc6c Make better use of instructions that clear high bits; fix various 2-wide shuffle bugs. 
llvm-svn: 45058
 2007-12-15 03:00:47 +00:00
Scott Michel 0aa7133f82 Start committing working test cases for CellSPU.

Evan Cheng 9556729128 Actually, MOVPQIto64mr is a dup of MOVPQI2QImr, MOV64toPQIrm is a dup of MOVQI2PQIrm. 
llvm-svn: 45041
 2007-12-14 20:08:14 +00:00
Evan Cheng e28372c0d6 Fix (mem) <-> low 64-bits of xmm bugs pointed out by David Greene. Mac OS X Leopard assembler recognizes movq.

Dale Johannesen f7cefdd5f0 x86-32 long doubles are 4-byte aligned on the stack 
for parameter passing (only for that, on Darwin).

llvm-svn: 45030
 2007-12-14 15:10:00 +00:00
Evan Cheng 0e6408124e Fix ctlz and cttz. llvm definition requires them to return number of bits in of the src type when value is zero. 
llvm-svn: 45029
 2007-12-14 08:30:15 +00:00
Evan Cheng e9fbc3f014 Implement ctlz and cttz with bsr and bsf. 
llvm-svn: 45024
 2007-12-14 02:13:44 +00:00
Bill Wendling cb77f04e1f Add flags to indicate that there are "never" side effects or that there "may be" 
side effects for machine instructions.

Evan Cheng 6e68381e02 Implicit def instructions, e.g. X86::IMPLICIT_DEF_GR32, are always re-materializable and they should not be spilled.

Duncan Sands fde556745b Remove host endianness info from TargetData and 
put it in a new header System/Host.h instead.
Instead of getting the endianness from configure,
calculate it directly.

Dan Gohman 7a7742c2fe Allow vector integer constants to be created with 
SelectionDAG::getConstant, in the same way as vector floating-point
constants. This allows the legalize expansion code for @llvm.ctpop and
friends to be usable with vector types.
