Evan Cheng 8cbbc7944d Fix another register coalescer crash: forgot to check if the instruction being updated has already been coalesced.

Owen Anderson 86837616f7 Banish global state from ScalarEvolution! SCEV uniquing is now done by tables attached to the ScalarEvolution pass. 
This also throws out the SCEV reference counting scheme, as the the SCEVs now have a lifetime controlled by the
ScalarEvolution pass.

Note that SCEVHandle is now a no-op, and will be remove in a future commit.

Bob Wilson b8b636d145 Recognize and handle ARM v7 target triples for Darwin.

 2009-06-22 18:01:28 +00:00
Fariborz Jahanian 3a36343b88 Remove ImplicitMustBeDefined, use universal 'Used' flag 
instead. Do the implicit default ctor checking in MarkDeclarationReferenced.

Bob Wilson 360eef0782 Fix llvm-gcc build for armv6t2 and later architectures. The hasV6T2Ops 
predicate does not check if Thumb mode is enabled, and when in ARM mode
there are still some checks for constant-pool use that need to run.

Argyrios Kyrtzidis 49abd4d95b Addressing Doug's suggestions:

Dan Gohman ed627385de Make use of getUMinFromMismatchedTypes when computing backedge-taken 
counts for loops with multiple exits, replacing more conservative code
which only handled constants. This is derived from a patch by
Nick Lewycky.

This also fixes llc aborts in ClamAV and others, as
getUMinFromMismatchedTypes takes care of balancing the types before
working with them.

llvm-svn: 73884
 2009-06-22 15:09:28 +00:00
Dan Gohman 2bc22305d2 Add a getUMinFromMismatchedTypes helper function. 
llvm-svn: 73883

Duncan Sands 376c6f16de Include cstdio to get EOF, needed with gcc-4.4.

Chris Lattner 1d1fe918de process memory operands with a parenthesized expression for a displacement, 
like "(4+5)(%eax)".

 2009-06-22 06:35:58 +00:00
Chris Lattner 7fdbce7a60 Implement full support for parsing primary expressions. We can now parse 
all of health and voronoi (ignoring directives).  We only get 409 lines into
176.gcc though because we don't have binary operators yet:

Parsing 176.gcc.llc.s:409: unexpected token in operand list
	movsbl	_arityvec+1(,%edi,8), %eax
	      	         ^

Chris Lattner a7b51ed5e6 implement parser support for '*' operands, as in "call *%eax". 
llvm-svn: 73876
 2009-06-22 06:02:13 +00:00
Chris Lattner 78db36271c implement memory operand parsing.

Dale Johannesen d3f7935f50 Testcase for (llvm-gcc) 73873. Usually 
std::pair<double, float*>
is 16 bytes on darwin-powerpc, but not always.
See testcase for full weirdness.

Dan Gohman 692b46872e Factor out code for computing umin and smin for SCEV expressions into 
helper functions. Based on a patch by Nick Lewycky.

llvm-svn: 73869
 2009-06-22 03:18:45 +00:00
Chris Lattner e5074c46b2 start implementing some simple operand parsing. 
llvm-svn: 73867
 2009-06-22 01:29:09 +00:00
Dan Gohman 96212b661c Teach ScalarEvolution how to analyze loops with multiple exit 
blocks, and also exit blocks with multiple conditions (combined
with (bitwise) ands and ors). It's often infeasible to compute an
exact trip count in such cases, but a useful upper bound can often
be found.

llvm-svn: 73866
 2009-06-22 00:31:57 +00:00
Dan Gohman 13037149b9 Delete an unused variable. 
llvm-svn: 73865
 2009-06-22 00:19:17 +00:00
Dan Gohman 78ea89e161 Fix this code to correctly handle loops with multiple exits. Until 
now, this hasn't mattered, because ScalarEvolution hasn't been able
to compute trip counts for loops with multiple exits. But it will
soon.

llvm-svn: 73864
 2009-06-22 00:15:15 +00:00
Dan Gohman 860379bcc2 Rename a variable for consistency with the ExitBlock vs ExitingBlock 
terminology that LoopInfo uses.

llvm-svn: 73863
 2009-06-21 23:48:38 +00:00
Dan Gohman 0104842ee3 Fix ScalarEvolution's backedge-taken count computations to check for 
overflow when computing a integer division to round up.

Thanks to Nick Lewycky for noticing this!

Chris Lattner b013345338 stub out parser for asm files. Change invariant on lexer to always 
print its error message when it returns an asmtok::Error token.
Compute a proper error code for llvm-mc in 'lex' mode.  Add new
-as-lex option to enable lexing mode (vs parsing mode).
